This Victron converter charges a 12/24V service battery in vehicles fitted with an intelligent dynamo. It accepts 10 to 30 V in and delivers 10 to 30 V out, with a continuous output current of 100 A. The output is rated at 100 A on a 12 V output and 50 A on a 24 V output. Standby consumption is 7 mA, DC connections are M8 bolts, and the unit weighs 4.1 kg.

Our take

The 100 A figure applies to a 12 V output, and it drops to 50 A on a 24 V output. So the current you can push into a service battery depends on which voltage that bank runs at, and a 24 V bank gets half the amps.

From our buying guide

Each maker sets its own alternator rules. Battle Born calls a DC-to-DC charger a simple and safe way to use alternator charging.

Check before you buy:

  • It can follow your battery's profile, since not every charger can follow a lithium maker's.
  • Battle Born warns that a BMS shutdown leaves the vessel without power, and that one during alternator charging can severely damage the alternator.
