So what am I missing here, the OP said he charges at 30 amps and discharges at 30 amps, then says charging at 40, now I only charge at 10 amps and takes roughly 18 minutes to charge my battery, not that I have timed it, but I have it fully charged just before hitting the track, now logic tells me if I was charging at a higher rate, the battery should be done sooner, as I can even charge a 4s in 22 minutes at 10 amps (balance charge - fast balance) so what am I missing?
My charger is a icharger 308 & 406 and I start charging my batteries 3 heats before I am up.
