The Orion-Tr Smart 48/48-8A is an isolated DC-DC charger rated at 380W. It charges in 3 adaptive stages, bulk, absorption and float, and is designed for dual battery systems where the starter battery's alternator charges a service battery. Bluetooth is built in for monitoring and configuration, and a remote on/off switch can control it. The isolated design keeps input and output chassis grounds separate. It works with lead acid and lithium batteries, with full rated output up to 40°C and operation up to 55°C.
Our take
The separate input and output chassis grounds are the point of this 48/48-8A model: the charger links two sides without tying their grounds together. Full rated output holds up to 40°C, while operation continues up to 55°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.
