Off-road Addict Posted October 25, 2020 Share Posted October 25, 2020 Getting an Axial SCX10 3 gladiator. Can anyone recommend a 5000mah 3s battery and charger to match. Or would a different mah be better. Looking to do crawler stuff 😎👍 Quote Link to comment Share on other sites More sharing options...
mugen mad Posted January 11, 2021 Share Posted January 11, 2021 So one of my lipos has failed on 1 cell its reading 1.4v has been stored for a while now is there a way I can bring it back or not as the other cell is still reading 3.8 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted January 11, 2021 Share Posted January 11, 2021 I dont think so and probably not worth chancing it if it can be brought back Quote Link to comment Share on other sites More sharing options...

Best to just write it off as a bad lipo and dispose of it correctly. Quote Link to comment Share on other sites More sharing options...
mugen mad Posted January 11, 2021 Share Posted January 11, 2021 I saw a post on here somewhere about charging it on nimah setting briefly and it seems to have worked for now Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted January 11, 2021 Share Posted January 11, 2021 That's correct. What voltage are the cells at now? I'd keep a close eye on it if you choose to use it, there's a good chance that the cell that dropped low will be massively out of balance. Don't get me wrong, I've used the NIMH truck myself a few times but I'm aware of the risks and accepted that it might end badly. Quote Link to comment Share on other sites More sharing options...
DogBone Posted March 16, 2021 Share Posted March 16, 2021 Is there a preferred site people use to get lipos thats cheap or are they all pretty much the same? And are cheap ones with the same values as good as more expensive branded ones? Quote Link to comment Share on other sites More sharing options...

Seem pretty decent and always handy with next day delivery.. 🙂 1 Quote Link to comment Share on other sites More sharing options...
DogBone Posted March 17, 2021 Share Posted March 17, 2021 Nice, thanks. I'll look them up. Also about chargers. How good a one do I need? I was looking at etronix powerpal 3.0 ac/dc performance charger/discharge for £43. Any good or are there better ones for the money or do I need a REALLY good one?

Pez1984 Posted March 17, 2021 Share Posted March 17, 2021 I went with the overlander mini+ which seems pretty decent. In hindsight I wish I'd spent a bit more and got one that could charge 2 batteries at the same time. Depends how many batteries you'll be charging before you go out. 1 Quote Link to comment Share on other sites More sharing options...
Seminole81 Posted March 17, 2021 Share Posted March 17, 2021 (edited) Hi All, Completely new into RC and LiPo batteries. Can I just confirm I’m reading this correctly? I have 2 x 7.4V 30C/60C 4000mAh batteries. I set charger to LiPo and only set to 3V as the 5V would be too much for these batteries correct? Is it then just a case of plug everything in (so connect battery to charger via the cables sticking out of charger and then the little white one into the 2S 1S port? What’s the temp sensor bit for (what do I put in this?) do you place the batteries into the safe bag whilst charging? I don’t think this charger has anything else (it’s a basic one) so how would I store these? Is it charge them up and then run a few minutes on them for storage if required? also do I charge first before using or run straight away? I’m guessing this is just a balance charger only (it’s the Etroniz Powepal Peak Plus, part no ET0209E. edit: second reading I don’t use the black and red cables unless it’s for Ni** batteries? Just use he 2S 1S port? Or are these the balance terminals for LiPo? Instructions say: confirm LED off set battery type to lipo set current parameters (3v Fo my batteries?) connect balance terminal (red and black? Or is this the white one?) connect battery (opposite of last step?) thanks in advance Edited March 17, 2021 by Seminole81 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted March 17, 2021 Share Posted March 17, 2021 do you mean setting the Amps to 3A ? Quote Link to comment Share on other sites More sharing options...

Stormbringer Posted March 17, 2021 Share Posted March 17, 2021 that will be fine mate and ocaissional 5A charge if in a hurry shouldnt hurt either but the 3A charging will be best 1 Quote Link to comment Share on other sites More sharing options...

There are more options than you can shake a stick at, depends how much you want to spend & how fast you want to charge your batts essentially- some light reading for the lipo / charger beginner: http://www.robotwars.00server.com/tutorials.html 1 Quote Link to comment Share on other sites More sharing options...

Seminole81 Posted March 19, 2021 Share Posted March 19, 2021 Just looking at this charger more and the whole storage thing. It appears my charger doesn’t have that function nor does it have a 50% charged light. It’s either charging or not charging. So working it out, 4000mA battery x 3A charge = 1.3hrs for full charge, but that’s from dead (which should never happen) and doesn’t take any other factors into account. So for a “storage charge” should I just half the charge time for about 50-70% battery life? Quote Link to comment Share on other sites More sharing options...

In theory yes, in reality you really want a voltage checker for lipos so that you can actually see the individual cell voltages ( ~3.8v per cell for storage charge ). Better yet, buy a better charger- £30-35 gets you everything you need these days. Quote Link to comment Share on other sites More sharing options...

It was a case of trying to get best bang for buck so to speak and I had a pretty strict budget so that's why I went with the charger I got. Will see about getting another one though if my son takes to it like I'm hoping he will. Quote Link to comment Share on other sites More sharing options...
DogBone Posted March 25, 2021 Share Posted March 25, 2021 Do I do storage charge after every use, even if I'm using it the next day or is it safe to just charge up to full and leave over night? Also is storage charge done at 1A? Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted March 25, 2021 Share Posted March 25, 2021 Most chargers are only capable of 1A max discharge, even if you set it higher. I always storage charge as soon as I'm home from bashing, but realistically charging them up and leaving them overnight isn't going to hurt. 1 Quote Link to comment Share on other sites More sharing options...
Seminole81 Posted March 29, 2021 Share Posted March 29, 2021 So, looking into the batteries and charger I've got a bit more. Still haven't tested it. Big man's birthday is Saturday so plan on opening it up and throwing them on charge then and doing a few mods before taking the Quantum Flux out for a first run. It appears the charger I bought doesn't have a battery status indicator. It's either charged or charging. So how do I do a storage charge on this? Is it a simple case of doing the maths? 4000mAh battery x 3000mA charge = 1.3hr for full charge (1hr 20 minutes). This doesn't take any other factors into account, nor does it take into account that the battery actually won't die. So if we say 20% left on when cut-off, that would mean full charge of about 1hr 4minutes? So with that in mind, if I just charged for 32 minutes after use that would give me the storage charge of about 50%? Thanks in advance, and yes I will invest in a better charger soon 😄 Quote Link to comment Share on other sites More sharing options...
