For lead-acid batteries 6 to 24 V/DC. With this battery backer, 2 batteries are charged separately from each other at one charging current source (car alternator, solar systems, wind turbines, chargers, etc.). For charging currents up to max. 10 A (with cooling 20 A). The charging current is distributed in such a way that an empty battery is charged more than an almost full battery. Ideal for motor caravans if one battery is used to operate the TV, radio etc. and the second battery must remain full to start the engine. Or for weekend homes when a battery for the alarm system must not be drained.

For battery type: SLA, gel (VRLA), AGM (VRLA), wet (liquid)
