Nick Posted April 10, 2005 Share Posted April 10, 2005 I need a charger that has an LCD screen so I can see what condition my batteries are in. The charger must do upto 8 cells, but I would love to be able to do 16 cells at once. I would like it to be mains, but if you recommend a 12v charger, could you please also reccomend a 12v source. I really need something to charge 14 cells faster, at the moment I have a "Pro-Peak Varipulse" and it does one battery at a time on 3A taking around 2 hours! Thanks, Nick.

waz Posted April 10, 2005 Share Posted April 10, 2005 Look at a Superbrain 959. Quote Link to comment Share on other sites More sharing options...
Nick Posted April 10, 2005 Author Share Posted April 10, 2005 Looked at them, but I heard they false peak really bad. Can you comment this statement? Quote Link to comment Share on other sites More sharing options...
Delboy Posted April 10, 2005 Share Posted April 10, 2005 I've been using the eagle CDC for not far off a year now, love the thing, not had a single problem with it, hasn't false peaked a single time. Can do upto 10cells. Can get the AC/DC version for £150 Quote Link to comment Share on other sites More sharing options...
Nick Posted April 10, 2005 Author Share Posted April 10, 2005 Looking for something around £50-70. Quote Link to comment Share on other sites More sharing options...
Harvey Posted April 11, 2005 Share Posted April 11, 2005 For that sirt of money id say the BMI digipeak 14 - i believe it does 14 cells (hence name) so unfortunately not quite what you want. But it has an LCD screen - can show volts, amperage and mah charged/discharged. It also discharges, but i think only up to about 6-7 cells (it wont discharge my transmitter batteries. It will only discharge about 1.5- 1.75amps unfortunately tho. But i think its a very good charge - trickle charges, + adjustable fast charge from 0.3 - 5 amps. Comes with lead for tamiya plugs, and one to plug straight into a transmitter (plugs into my acoms anyway) and came with another lead... but cant remember now. maybe it was a reciever battery pack connector. Its about £60-65, the only downside for you is it only runs off 12v. I converted an old 250W ATX to run it and it works fine I think you can get a AC/DC version (maybe under a different name - think it was the mtoniks site i saw it on). But TBH id prefer saving about £40 for the smaller and lighter DC one and carry on using my PSU/ 12v car battery. Quote Link to comment Share on other sites More sharing options...
Samari Posted April 11, 2005 Share Posted April 11, 2005 Looked at them, but I heard they false peak really bad. Can you comment this statement? From what I've heard they're one of the best chargers around. They can do two packs at once aswell which is good for the E-Maxx. I'm not sure if you can buy them in the U.K yet.

mth Posted April 11, 2005 Share Posted April 11, 2005 i heard bad things about the superbrain thingy to. the only other chargeri know of that can do 2 packs at once is the yokomo BCS double....i had one, sent it back because the screen pakced up. they then sent it to yokomo in japan nd the damn fools lost it....so we got a 200 pound credit from CML (chargeronly cost us 80 from someone we know ) anyway..that charger was crap anyway. what about that triton you showed me nick? that looked like a fairly good charger.

Nick Posted April 11, 2005 Author Share Posted April 11, 2005 It would cost £80 then I would need to find a 12v powersupply... Looks like the best charger for money though by far! Just thought someone might know of any others... Quote Link to comment Share on other sites More sharing options...
mth Posted April 11, 2005 Share Posted April 11, 2005 then the propeak PSU which is 35quid (2amp)....we just ordered one Quote Link to comment Share on other sites More sharing options...
Nick Posted April 11, 2005 Author Share Posted April 11, 2005 Buying the Triton - my Dad just gave me his Caravan battery because he wants this new one thats coming out (the exciting life of my Dad, lol). Should be good. 24 cells at once, mmmm. Quote Link to comment Share on other sites More sharing options...
mth Posted April 11, 2005 Share Posted April 11, 2005 lol...have you got a decent charger for it though? when i aint using our 12V batts...we just stick them on trickle Quote Link to comment Share on other sites More sharing options...
Nick Posted April 11, 2005 Author Share Posted April 11, 2005 Yeh, have this trickle charger thingy for it, works though. Quote Link to comment Share on other sites More sharing options...
ba57ard Posted April 11, 2005 Share Posted April 11, 2005 NIck are you planning on putting 2 packs in series to try and charge them that way?? Quote Link to comment Share on other sites More sharing options...
Nick Posted April 11, 2005 Author Share Posted April 11, 2005 I don't know what that means, so here is a picture of how. I will be making this connector thingy (attached picture) and charging 2 batteries like that. Is that alright? Why do you ask by the way? I have a feeling that you can charge 2 batteries at once wrong. Quote Link to comment Share on other sites More sharing options...
Samari Posted April 11, 2005 Share Posted April 11, 2005 Yes you can charge them wrong. You'll need to find out if that charger is meant to charge them in paralell (sp?) or in series. Quote Link to comment Share on other sites More sharing options...
Samari Posted April 11, 2005 Share Posted April 11, 2005 That picture looks like it is set up as a series. Quote Link to comment Share on other sites More sharing options...
Nick Posted April 11, 2005 Author Share Posted April 11, 2005 Good, charger says it can do series. Quote Link to comment Share on other sites More sharing options...
Harvey Posted April 11, 2005 Share Posted April 11, 2005 It will be in series. That is how the batteries are connected, positive to neg - neg to positive etc. So by using that 2 way series connector the charger would see 2x6 cell packs as 1x12 cell pack. I presume they would charge a lot better this way if you completely discharge the equalize the cells first, and of course all cells are the same. I might make a 2 way like that for my 2 sanyo 3000's on my BMI. That way i can charge them quicker prior to racing - then top them up individually 10 mins before racing Quote Link to comment Share on other sites More sharing options...
Nick Posted April 12, 2005 Author Share Posted April 12, 2005 My cells arn't matched and I don't have an equalizer either. Does this mean one battery would false peak or be incorrectly charged? Quote Link to comment Share on other sites More sharing options...
Harvey Posted April 12, 2005 Share Posted April 12, 2005 TBH i dont know. So long as you discharge both battery packs before hand it should be ok. It should hopefully detect the drop off in volts required when one pack is charged, just obviously keep a good eye on them, at least for the first few charges to check one of the packs isnt getting excessively hot. As they will both be the same batteries (all 3300 arnt they?) it should be fine. Obviously cells can go out of sync with themselves in a 6 cell pack - and the charger copes with that - so i think it will be fine with 2 packs - so long as you dont do something like connecting one pack with 10% power in with a pack with say 50% power left! Hence why i suggest discharger each pack before a recharge Quote Link to comment Share on other sites More sharing options...
