12V BMS – UFLEX
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.
