Description
The DC to DC Battery Charger is the top choice for charging your secondary batteries from the starter battery. It is compatible with various alternator types and offers precise charging for AGM, Flooded, Gel, and Lithium deep cycle batteries. With a 3-stage battery charger and advanced electronic protections, users can trust that their batteries are being efficiently and automatically charged.
Additionally, the charger isolates the input from the output to prevent any incorrect voltage transmission, ensuring ultimate safety. Its compact and durable design makes it easy to install on RV's, commercial vehicles, boats, yachts, and many other applications.
Protect Your Starter Battery
Renogy's DC-DC battery charger works seamlessly with traditional and smart alternators. The included D+ Ignition cable identifies generator starts, safeguarding the starting battery from over-discharge and protecting the generator. (Recommended: 18-16AWG copper cable. D+ Ignition Cable not included.)
Smart Charging Protection
The DC-DC battery charger's LC wire automatically adjusts the charging current, safeguarding the house battery from potential damage due to excessive charging. (Recommended: 18-16AWG copper cable. LC cable not included.)
Smart 3-Stage Charging
Efficiently charge your house batteries from the starter battery with Bulk, Boost, and Float stages, ensuring automatic and optimal charging up to 100%.
Prolong Battery Lifespan
Automatically adapts charging modes to match battery voltages, while the temperature sensor provides -3mV/°C/2V compensation, ensuring optimal charging in varying temperatures. (Please note that the temperature sensor is not included. If the lithium battery has a built-in BMS, an external temperature sensor is unnecessary.)
