vehicle or solar inputs. A Bulk re-start will occur when battery voltage drops below 13.3V DC.
Smart Charging Feature
The ePOWER DC2DC+ Battery Charger will regulate its output based on the loads connected
to your battery banks. This function is important to maintain the life of your battery banks as
some battery chargers mistake loads for discharge and continue to keep the batteries in the
bulk or absorption stage for extended periods of time, which will damage the battery bank.
The ePOWER DC2DC+ Battery Charger has two methods of load based regulation to ensure
your battery charger transitions to oat when it should do so.
