Just don't STORE at full charge then, charge them (fully), stick them in your bot, bash other bots around!
And then balance at a very low amperage as often as possible to keep them in good condition.
seriously, how long to these things take to charge/discharge?! I let it balance charge last night for 5 hours and it only got to 2800 out of 4800mah?! it went into this funny routine where one of the cells reached 4.2v and the overall charge amps started to jump from 0A up to 0.5A, rather than being at 1.5A (which i know isn't great). Its currently discharging to storage level at 0.2A (thats the max i can get out of it), at this rate, its going to take 14 hours to discharge the 2800mah!
proberbly not, it depends on how many amps the load is how long it will take to discharge.Originally Posted by Danjr1
ie:
a 4000mAh batt wiv a 8000mAh load will take half an hour to fully disharge if fully charged
How many amps are you charging this batt at?
it was charging (on balance charge) at 1.5A (which i know isn't great but i didn't know) until one of the cells got to 4.2v. At this point, the Amperage started to basically bounce from 0A to 0.5A so the charging slowed right down! I can't make the discharge rate go any higher than 0.2A
What charger are you using?
an Imax B6 from ebay. not the most amazing one, any recommendations for a new one? Just had a rebate from the taxman!
try some of the the fusion range from logic r/c.
they are top quality
orr some of the more expensive ones £50+
ill have a look around. Out of interest, what discharge rates are other people getting on 22.2v Lipos?
Might treat myself to this:

I got one of those eBay iMax6's £8 couldn't resist!
STOP DISCHARGING!!!Its currently discharging to storage level at 0.2A
Are you saying it's ok to store the battery at, say, 23.5v cos that's what it's at now? I'm not planning on using the battery for while until the robot is ready.
PJ, do you just charge your new lipos to full, use them in the robot and then charge them back up again?
Had a look around the Internet and bringing them down to 3.85v for storage seems to be the general consensus?
