Victron Energy® - BMS 12/200 for lithium batteries

A 12V BMS that protects the alternator (and wiring), and supplies up to 200A in any DC load (including inverters and inverter/chargers)

 

Why a Battery Management System (BMS) is needed:

• A LFP cell will be damaged if the voltage over the cell falls to less than 2,5V.

• A LFP cell will be damaged if the voltage over the cell increases to more than 4,2V.

• The cells of a LFP battery do not auto-balance at the end of the charge cycle.

 

Alternator/battery charger input (Power Port AB) - Features

• The first function of Power Port AB is to prevent the load connected to the LFP battery from discharging the starter battery.

• Control of transients and input voltage.

• Charge current is reduced to a safe level in case of cell unbalance or over temperature.

• The input current is electronically limited to approximately 80% of the AB fuse rating. Choosing the right fuse is very important.

 

Load/battery charger output/input (Power Port LB) - Features

• Maximum current in both directions: 200A continuous.

• Peak discharge current electronically limited to 400A.

• Battery discharge cut-off whenever the weakest cell falls below 3V.

• Charge current is reduced to a safe level in case of cell unbalance or over temperature.
