What is everyone's usual charge rates on a pack like these? I've been hitting them with about 10-12a of charge rate, would less be better on them or should I hit them with the full force? The instruction sheet said to never charge them below a 1c (5a) rate.
After a race some people "dump" their packs. Are yall discharging them to 6v and then charging back up to storage voltage ( 7.4v-7.6v)?
I replied back to your PM but I'll post here as well.
After I finish racing for the day I will just put my packs away with what ever charge is left in them after a 5-6 minute race and leave them until next race day. When I get there for the next race day I will discharge them first and then fully charge them for practice. It seems to help them last longer and perform much better all day when doing this. I normally charge at 15 amps but have gone to 20 with absolutely no issues at all...ever. But I usually only crank them up that high if I am running behind on time or forgot to charge. 12-15 is a good safe number for guys wanting to charge higher to get on the track quicker. I never store a pack below 7 volts for a long period of time either.
