Product Specifications

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

①Multi-chemistry battery types ( flooded, gel, AGM, and lithium)

②3-stage charging (bulk, absorption , and float)

③Smart protection features ( battery lsolation, over-voltage safety, overheat protection, and short circuit protection)

④Overcomes voltage drop caused by long cable runs

⑤Able to charge an auxiliary battery to 100% state of charge

⑥Increases run time of loads, such as fridges and lights

⑦Prolongs battery life
