Collection: Battery Charging

Everything needed to charge a battery, from the mains or on board: 230V chargers for LiFePO4 from 12V to 60V and currents up to 20A, including IP67 versions for exposed installations, Sterling Power BB1260 60A DC-DC alternator chargers and Redarc BCDC units with built-in MPPT at 40A and 50A, which handle solar and alternator together.

The figure to check first is the end-of-charge voltage: a nominal 12V LiFePO4 wants 14.4-14.6V, a 48V one about 58.4V. A lead-acid charger with a desulphation stage can go past those limits and trip the BMS.

The current is sized at around 0.2-0.5C of the capacity.
