A lithium ion battery charger is different from a standard charger. We have the correct charger for every battery in our range. They have the right charging profile (CC~CV) to safely and quickly recharge your Belly Boat Battery. Never charge a lithium battery with another type of charger. This may damage your lithium battery and prevent it from working optimally.


A standard charger that you use to charge a lead-acid battery is not compatible with a Lithium battery. The special lithium chargers have a modular charging curve in which the charger slowly builds up the charging current and then, as the battery voltage increases, slowly reduces the charging current. In this way, a lithium battery is fully charged and the BMS has time to balance the individual lithium cells. This ensures that your lithium battery performs optimally and increases its service life.


To determine which lithium ion charger you need it is important to determine which type of lithium battery you have. A 3S Lithium Battery (Li-ion) has a charging voltage of 12.6V and a 4S Lithium Battery has a charging voltage of 16.8V. All chargers with a black plug are suitable for Lithium 3S (12.6V) and all chargers with an orange plug are suitable for Lithium 4S (16.8V) batteries. The charging current in Ampere affects the speed at which the battery is charged. For optimal charging there is a rule of thumb; 1C=10% of the battery capacity. So a 100Ah battery can best be charged with a 10A charger, a 50Ah Lithium battery with 5A. Of course, a 50Ah Lithium Battery can also be charged with a 10A Charger and a 100Ah Lithium Battery with a 20A Charger.
