Battery Control Booster MT BCB 25/20 IUoU

The Battery Control Booster MT BCB 25/20 by Büttner Elektronik is the ultimate 3-in-1 solution for optimally charging your RV battery/b>atteries. The booster can be installed in parallel to the existing charging technology in the recreational vehicle.

1. At the 230 V mains: The BCB supports any existing charger with additional 20 A and fulfils the charging characteristic required by the battery manufacturer with its temperature-controlled IUoU characteristics (liquid acid/gel/AGM/LiFePO4).
2. While driving: Thanks to the booster function, the MT 25/20 BCB optimises charging while driving. Again, the IUoU charging is active and, depending on the charging state, the BCB supports charging with an additional 25 A. Voltage loss due to long charging lines is fully compensated. Hence, it guarantees a full charge at longer distances; overcharging the RV battery is impossible.
3. Pulser function: can be activated. Prevents falling out of the Pb-batteries due to sulphating.

Installation: The BCB 25/20 includes a high current relay with cable kit and fuse, which makes installation extremely easy even in vehicles with pre-installed electronic block (EBL, CBE).
