40A DC to DC Dual Battery Charger
Product Introduction
SDC DC-DC charger, capable of maintaining auxiliary battery system charging throughout the journey. DC-DC battery charger is designed specifically for dual battery systems, ensuring reliable performance The auxiliary battery system operates at peak efficiency for a longer period of time when disconnected from the power grid. When the engine is running, the DC-DC charger will safely charges the auxiliary battery pack. Supplements for RVs, ships, or any other off grid vehicles.
Product features
1. Multi-chemistry battery types ( flooded, gel, AGM, and lithium)
2. 3-stage charging (bulk, absorption , and float)
3. Smart protection features ( battery lsolation, over-voltage safety, overheat protection, and short circuit protection)
4. Overcomes voltage drop caused by long cable runs
5. Able to charge an auxiliary battery to 100% state of charge
6. Increases run time of loads, such as fridges and lights
7. Prolongs batter y life
