Smart 6V/12V battery charger for diverse vehicles

The BFKK 5A charger handles 6V and 12V lithium (LiFePO4) and sealed lead-acid batteries including flooded, GEL, AGM, VRLA, deep-cycle and maintenance-free types. It suits cars, motorcycles, ATVs, lawn tractors, trucks, SUVs, boats and classic cars. A memory function recalls the last voltage mode used.

Replaces manual chargers

The unit runs battery test, desulphation, soft start, bulk, absorption, analysis and float stages without user intervention. It charges small batteries from 5Ah to 100Ah and maintains larger ones from 10Ah to 120Ah. The jump is worth it when you want unattended winter maintenance and protection against overcharging.

Sustained float mode keeps batteries ready without

After a full charge the charger switches automatically to float mode, optimising power without overcharging. Spark-proof operation and reverse-polarity protection prevent output until connections are correct. Note that batteries below 3.6V are treated as bad and will not charge normally.
