The 25A Buck-Boost DC/DC converter takes an input of 10 to 30 V and delivers an output in the same 10 to 30 V range. Continuous output is 25 A, and the output current is fully rated up to 60 °C. It has engine running detection and a remote on/off terminal. On a 24 V output the maximum drops to 15 A.

Our take

The 25 A rating applies on a 12 V output, while the 24 V maximum is 15 A. Check which side of the converter your service battery sits on before counting on the full 25 A.

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.
