The Victron 50A Buck-Boost DC/DC converter accepts 10 to 30 V in and delivers 10 to 30 V out. It is rated for 50 A at 12 V and 25 A at 24 V. The case weighs 1.4 kg and the output is fully rated up to 60 °C. It shuts down on under voltage at 10 V and draws 7 mA on standby.

Our take

The output is rated 50 A at 12 V but only 25 A at 24 V, so the current you can draw drops by half on a 24 V bank. Check the load against that 24 V figure first. The full rating holds up to 60 °C.

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.
