Float Charge or Re-Bulk charge

- Battery is fully charged and maintained at a safe level.

A fully charged Lead acid battery (GEL, AGM, WET and Calcium battery) has
a voltage of more than 13.8 Volts; if the lead acid battery voltage drops to
12.8V at float mode, it will return to Bulk charge; Li-ion,LiFePO4 and LTO
battery have no float mode; If a Li-ion battery voltage drops to 12.0V after
absorption stage, it will return to Bulk charge; if a LIFePO4 battery voltage
drops to 13.4V, or LTO battery voltage drops to 13.2V after Absorption stage,
they will return to Bulk charge
