antigravity lithium is reading - resting voltage 13.11V

that's way high .. certain bikes will actually charge at higher voltage at idle. but yours is charging at too high a rate and will severely overcharge agm and LiFePO4 both. 15.9v is way too high.

what's the voltage at mid-engine rpm? too high will severely overcharge your LiFePO4 battery and could cause internal pressure safeties on cylindrical cells to pop.

here's a chart to show LiFePO4 charge state voltage
