Li-ion batteries in general go from full power to NO power. the instant battery output goes down... STOP all drain! or risk over discharging/ruining your battery.

normal 12v charging system charges at 13.8 to 14.2v ... LiFePO4 fully charged at 14.6v ... so any working 12v charging system will charge just fine. so no special charging system are needed for LiFePO4 motorcycle batteries.

balancing is needed only on occasional basis to make sure all internal cells remain in balance. Earth-X has internal BMS that keeps cells balanced.

one of the most common problem with LiFePO4 batteries is mfg spec only enough AH for warm weather, with bike in perfect tune. actual amp hour are tiny with little to no reserve should engine need extra cranking and/or use of heated gear combined with short rides and cold weather.
