24v input at up to 35 amps and output is 24v at up to 35amps.

Simply connect in between a starting battery and house bank and any time the vehicle’s alternator is running this smart charger will smart charge the output bank.

Pre-set Charge Profiles and one user customizable battery charging profile available.
No risk of starter battery discharge. Current is NOT taken from the input battery and given to the output battery except during the low voltage timer for regenerative braking mode. This time frame can be increased in length or brought down to 0 seconds.
Includes battery temp sensor 10m cable
Regenerative braking / smart alternator mode can operate without an ignition feed
