Victron BMS 12/200 for 12.8 Volt Lithium-Iron-Phosphate Batteries.

Especially Designed For Campervan and Motorhome Applications.

The Victron BMS12/200 is a simple solution to charging LiFePO4 (Lithium Iron Phosphate) batteries, from alternators.

Why is a Battery Management System essential for charging lithium batteries?

A Lithium Iron Phosphate Battery cell will be damaged if the voltage over the cell increases to more than 4,2V, similarly, the battery will be damaged if the voltage in the cell drops below 2.5v. The Victron BMS12/200 prevents these outcomes.

Safe Alternator Charging

Charging Lithium Iron Phosphate Batteries from a standard alternator poses the real possibility of burning out the alternator, as unlike lead -acid batteries, the current demand for a LiFePO4 battery, can even exceed the total ahrs of the battery. 

At low speeds (Like engine idle) the alternator cannot cope with the excessive high current demand, and will rapidly overheat, often to the point of burning out the coil.

The Victron BMS 12/200 will regulate the current demand from the battery thus keeping the alternator temperature at safe levels.
