I need help with kiddies 12v ride in jeep please.

[RCbutcher]

I brought my daughter a 12v jeep off ebay lwst year she was abit too small so it wasnt used much and I left the batteries hooked up. Its been just over a year now and thought ide get it charged for my daughter but I charged it over night the next day it worked but only afew minutes.

Im looking to replace the batteries now but wamted to advice on choosing some good ones or if I can stick just one 12v battery or not I dont know. I would also like to charge it on my lipo charger if that is possible idk if its nicad or nihm yet tho so need somebody whos experienced with these.

A possible fault Im worried about is it has a built in mp3 player which sounded awful so being the young dad I am and tinkering with rcs I thought ide fit a better speaker but somewhere in the process I think I shorted it out which I thought was odd as ive touched wires on speakers loads of times and never had a problem.

So I think that has done something to the battery thats why it wont hold a charge or something.

So ide like to get rid of the mp3 altogether and install new batteries preferably ones I can charge on a fast charger and see a screen with volts and mahs.

Then ill wire in a cheap mp3 player into the dash and fit ipod speakers lol.

[RCbutcher]

Right now it has 2 of these batteries. I think they are 6v each and thought mayb a single 12v would be better also the jeep is a cheap type so these batteries are bound to be too. Ill link the jeep for reference.

Also I knew I didnt have to mark them left/right but ive got into the habbit of doing things like that now taking things apart.

[RCbutcher]

The jeep is one of these.

Thats bad ass

 

stick 2 12v's in their in a similar size and it will go a lot faster, you can get these from component-shop, also they are Pb which is Lead in chemistry so they use lead acid batteries, so again you can buy a couple of 12v's and wack it up to 24v of power. which could be fun. 

 

Lead acid batteries dont like being left unused for a long time, its in the same vain as your car battery, dont use it for ages, finally get it started, then finds the battery wont take a charge (at this point most people think its an alternator) same theory here, the batts have probably died.

 

so your plan of action

go to component shop

go to the lead acid section

pick out 2 similar sized 6v's or 2 similar sized 12vs

wack em in! 

[HATZY]

pocket bike batteries tend to work. search your local area for a battery shop or electrical wholesaler, failing that there is always ebay. the PB stands for lead acid so will need to be trickle charged. i do my sons on my imax. you can use a 12v instead of 2 6v but thats if there is enough space. i doubt the amplifier on the mp3 player has any protection against shorts so thats probs why that wont work any more, i wouldnt have thaught it would kill the batt, although, leaving it connected for that amount of time will

[Thatsliam]

stick 2 12s heli lipo sticks in it.

[Randum]

What about just buying a couple of 3s packs and run in parallel to bump up the mah?

[Tamiyacowboy]

lol your all willing to help him smoke is daughters ride. 

 

ok fella what you have there are 6v 6ah SLA batterys

usually found in long stay items , wetaherstations etc etc.

 

charging it should be charged at a certain voltage at a certain capacity

to prevent venting and the production of harmful and explosive gasses.

 

to replace them you CAN use a 12v 12ah single battery ,you could run two

single 6v like you have in picture, or go a single larger but more ah to.

 

infact you could run two 12v 12 ah batterys to double up the capacity to a huge 24ah ( 24,000mah)

and still keep the 12v , so she could have nearlly 3 times the running time.

 

SLA batterys even if not used self discharge over time, they also furr up over time and loose charge/capacity

its time for them to go into recycle  

[HATZY]

i was just lookin at them posts and thinkin, lipo? really!?!

 

tamiya, how do you work out what a pb should be charged at? i normally do them at between half an amp and 1amp

[Randum]

What's wrong with using a similar voltage lipo with low voltage alarm? Or better still use a LiFe pack. Would be more practical as you can leave them charged and discharge till the car stops, safely charge at 1c. Will cost a little more but that's the route I would look at personally. Get a closer voltage to your pb battery aswell.

[Dom C]

It's RC, that's epic!

 

Needs a lehner and MGM!

[Tamiyacowboy]

what 12v lipo give you 12,000mah ? theres your answer. 

lipo is not a straight swap for ANY old battery system 

 

what happens when you swap old sytle batterys and replace with lipo batterys in a jumbo jet ? 

they set the plane on fire lol. not exactly what you want with your young child in the hot seat.

 

fast charging a PB is not good, your not giving the cells enough to to make the chemical changes required.

when the electrical current is passed between the lead plates and the weak acid it reacts they break down and release hydrogen and

oxygen ( bubbles in car lead acid batterys when charging) 

 

when charging i do mine at 1amp sometime will come down to as low as 0.1 amp on the final last hours , i check battery temp every 15 mins or so. if that battery warms up your feeding to much current in.

am not a fan of the SLA type cells, they have less lead plate in ( by weight/mass) and hence the battery is weaker than something like a car battery.

bigger and more heavy the battery the better it will preform , the better charge it will hold and more medium to convert the chemical changes from.

dont believe the MAH reading either. two batterys the same mah and voltage will be two totally differnet weights, the heavery of the two will be a more close match on the true MAH. china pumps these cheap rubbish out like rabbits so be aware and if possible feel the weight of cell before buying,

a 12v SLA battery should be weighing in around the 3kg mark, the cheap ones your looking at 1.2kg maybe a tad more. thats alot less lead and lower MAH,

 

 

there are a few forums dealing with beefing and modding childs ride-ons, 24 volters and some even more, but they have new electronics and controllers

to cope with the added voltages and currents your shoving into the power system. 

when your dealing with children you DO NOT throw them onto a LIPO loaded fire bomb. its stupid, its dangerous,

if your jumping onto the machine its your choice, but i would not be saying to lipo up the machine. 

 

 

to the OP : 

 

if your wanting something thats going to be fun and safe, i would pop to a couple local golf courses

ask to speak with green keepers and ask if they have any old golf cart batterys about you could maybe purchase for your childs ride - on toy ( they throw them away 9-10 times ) but your just going to take care and recharge slowly bring it back up.

mobility places to them OAP carts run same type of battery system abiet better speed controllers etc etc but same type of thing just adult sized.

you may get 4-5 batterys for nowt and only two are good buts its a bonus for you and keeps the little lady happy to

Thank you tamiya cowboy and purcy . hatzy for helpful answers.

I am just looking to make it drive again no added speed longer runs and easy charges would be nice. So I could use my lipo charger set to lead acid and 1amp?

There's a mobility scooter shop close by I could buy a battery from would I just use one set of battery wires or would I need to remove the batt plugs not being used. I could probably fit a small car battery inside it its pretty big.

Ive seen the guys modding them to 24v and putting washing machine motors in them but I love my daughter lol mayb when I have a 7yr old son ill look at something silly the ones on youtube look crazy fast and the young ones handle them well drifting and all sorts. But my daughter is my 1st and not even 3 yet so she will be babied a long time yet

[Randum]

2 x 6000mah 3s packs in parallel will give you 12000mah. At 12.6v fully charged. And yes I agree with you on the fact I wouldn't put my child in a car running it. Which is another reason why I suggested LiFe batteries. The motor will see whatever volts it gets and draw the necessary current anyway, depending on the electrical setup of the vehicle depends on if it would handle lipo. Chances are its just an inline switch activated by the foot pedal therefore no esc or pcb to fry. But due to the cons of running lipo, storage charge and over discharge problems I still wouldn't use them anyway and of course problems with shorting out. Another problem you may encounter is the fact the motor may require more amps than what the wires and switch can handle at 3s. Which I think is one of the points you are getting at.

The lead acid batteries will be cheaper and safer. But weigh more and take longer to charge. Which is another reason why I said I would use LiFe for a 1c charge rate.

Obviously this is my own personal views and although I am saying I would do it. Doesn't mean I am telling the OP or anyone else to do it.

[RCbutcher]

So does AH represent MAH on these.

I get what you mean randum but im nowhere near experienced enough to experiment lol look at the mp3 player lol ive played with stereos all my life and thought it would be easy then I shorted it lol. So im happy to just get it going as before but with a better brand of battery if I csn fit one 12v and get the same run times which I dont know how long these had never using it longer than afew laps of the garden but if it could go for half hour that would be cool.

Ide really like to use a digital charger too so I can see how many mahs it has.

The scooter shop idea sounds best to me as thers one on my doorstep.

Ill post a pic of the wiring it looks pretty awful tbh amd that's factory all I did was put the motors on and plug them in and fit the wheels and stuff but it was very cheap compared to the others.

[Randum]

Then stick with the same type of battery. If you are unsure and stuff and claim it to be cheap. Yes Ah is amp hour as opposed to mah milliamp hour. So 1000mah is 1ah.Like Millimetre and metre. Pop in that scooter shop if they can't help you they might be able to point you toward a battery specialist in your area.

[Tamiyacowboy]

the mp3 is no doubt ripped from a differnet device and thrown into the machine.

you tend to find this with alot of chinese stuff, take the spy cams they used to be mobile phone cams

and the pcb board was at one time a tamagoshi or something.

 

nodoubt the mp3 was running of some sort of buck converter / step down electronics.

not exactly expensive stuff but dirt cheap that just fries as soon as something moves lol. 

i have a good idea of the mess of the wiring from factory install, the usual throw it in dab solder here

here here and sell it.

 

aye something around 12v and say 6ah-12ah anything bigger in AH  will be fine to, just keep to 1 x 12v battery or 2x 6v battery,

charging just pop it onto PB mode set around 0.9 - 1a 

and let her run slowly ( with these types of batterys slow charge is good, fast charge is bad ), you want them lead plates saturated in ions

not a nice thin layer thats stripped off on first hookup and power use.

[HATZY]

tamiya my sons is a 6v jeep, would i need to do anything to the circuitry to add another 6v battery in or just hook another batt up in series? can get a pic of the leccys in it if that helps. im normally savvy with these sorts of things but dont want to blow it up lol. i was toyin with the idea of makin it rc with a brushed esc and a jumbo servo on the front

[dink1000]

on maplins they do 6v 10Ah and 12Ah batteries (you have 6v 10Ah) that are the same size as each other

 

how are they layed out in the vehicle ? (you have left and right marked on them)

[Tamiyacowboy]

for a 6v powered truck/car hatzy : 

 

your kinda stuck a bit here, you cannot up the voltage to much, but you can BOOST the MAH.

you take two 6v batterys of the SAME mah. now you hook both the positives and negatives of batterys.

what this does is keeps our 6V power need, but because we used say 6ah batterys we now double that to 12ah.

to now use that battery bank in the machine, you will hook your positive to the one of the 6v battery positives

and the electrics negative to one of the batterys negatives. 

 

the childs toy will still only see the 6v , but because we have doubled up the MAH the runtime will be longer.

if you only had say 20 mins runtime, your now looking at 30+ mins. there is never a full 100% gain the chemicals,

charging etc etc all affect the final outcome, remember every action has a reaction , your going to loose some not gain all.

but even an added 10 mins to a child seems a lifetime. 

 

 

CAN you upgrade a 6V toy into a 12V toy tami? 

 

hmmm well you can, i will not lie and say not its not possible as anything is if theory says so.

most will start at the first point, powersource the batterys, 

Next is the electronics, or a start that wiring needs to be beefed up so 16/14 gauge wire added 

an old defunct 12v machine can help as donor , you want a decent 12v speed regulator something upto the job.

without a decent SC your not going to get very far unless you feel like pushing machine. 

 

its not as easy as you think, just throw in a bigger battery and it works. 

these things are just not thought about on the drawing board, makers do not expect public

to volt mod the machines to 24v and 48v   drag strip runners.

 

BATTERYS : this is where the meat n potatoes is, a rubbish maplins cell will last like 5 mins 

a Yussa (sp) battery will last the full duration maybe even a tad longer. 

remember the lead content i talked about, well Yussa are like the omg of all cells.

check you motorbike , golf cart etc etc ( high grade goods) and nodoubt 8-10 times your going to find a Yussa

cell powering it. childs ride ons need that grunt and power so a decent battery will show its worth.

[dink1000]

i wasn't saying buy maplins ones just that the 10Ah and 12Ah ones are the same size

 

so with out knowing the layout of the batteries it's hard to suggest what to get

[Tamiyacowboy]

the OP has a dual 6v 12 ah  in parallel, he can shove a direct 12v 12ah -24ah cell in 

now worrys as much. or even go parallel  2x 12v 12ah to booth him to a huge 24ah ( 24,000mah)

 

hatzy has a single  6v nodoubt a 6-12ah cell. he is kinda naffed when it comes to a 12v mod,

the motors and electrics i dont think will cope with the parallel 12v volt mod, but being a single 6v cell it can be run in parallel

with another cell of the same MAH a  double up the max mah so 2x 6v @ 6ah would give a huge 12,000mah

 

my bad to i was not implying maplin cells are shoddy ( i do have a shoddy one from them myself)was more stating the creame dela creame

is Yussa and for pounds to volts is worth the money they cost.

 

it does all depend on if the batterys are wired for parallel or serial in  the machine.

these toys tend to be 12v so i would take a guess they running 6v in serial to gain the 12v requirement.

 

if the OP and hatzy could tell us if the two batterys are wired in serial or parallel

we could shoot a few ideas.

i think you are getting confused.

 

the OP has 2x 6a 10Ah batteries that are wired in series so he gets 12v 10Ah

 

if they are side by side in the car then yeah he should be able to replace with a single 12v battery but if they are layed out any other way then i doubt he'll have the room to fit bigger batteries

[HATZY]

all the pb batts ive seen from maplins are bad in some way, mostly that they are only half to 3/4 filled with conductive material so are generally quite a bit lighter than a good quality cell, especially in their booster packs.

 

cheers for the advice tam mate, i didnt think i would be able to boost it volt wise but considering the way the leccys are mapped out in this thing, it wouldnt be too hard for me to get a couple of better start caps and better wires throughout. from what i can see of it (ive had it all apart cleaning it and getting it workin as got it used with intermittant power) there is no really SC, just an all or nothing on/off switch with a reverser, 2 start caps and thats about it

Some great advice here thanks guys unfortunately the scooter shop has moved so that's that out of the window Uttoxeter is going to pot I can stand in the main area of town and be in a 40m vicinity of 12 shops 6 of which are empty and 4 have been since I moved here its appalling but anyway.

Thank you tamiyacowboy/cavalry lol you've helped me understand the set up alot better I think I will go with a single 12v rated to 10-12ah and see how far it gets her I could always put 2 in but only use one at a time if it was limited like a reserve tank lol thanks.

I contacted the shop I brought it from and they want
