My charger is a icharger 308 & 406 and I start charging my batteries 3 heats before I am up.
Only said I charge at 40 amps, not sure what you misread. The battery is taking an exceptionally long time to balance, because one cell is lagging behind in the balance process. Your charger may not provide you this type of info.
Regarding time, my other batteries charge in less than 10 minutes at 40 amps, and that’s from a completely drained state after discharging at 30 amps. If I charge a partially charged battery without discharging, it’s 5 mins or less.
