Universal Compatibility

Compatible with Multiple Battery Types

The DC-DC battery charger is fully compatible with a range of battery types including AGM, Flooded, Gel, and Lithium, resulting in optimal performance for all batteries.

Seamless Charging, Ultimate Safety

This charger utilizes advanced safety technology to ensure error-free and secure charging for your house battery.

Protect Your Starter Battery

The Renogy 12V 20A DC-DC Battery Charger is compatible with both traditional and smart alternators. Equipped with a D+ Ignition cable, it detects generator starts and prevents over-discharging of the starting battery, ensuring the safety of your generator. (For optimal performance, consider using an 18-16AWG copper cable. D+ Ignition Cable sold separately.)

Smart Charging Protection

The included LC cable allows for automatic adjustment of charging current, providing protection for the house battery against potential damage from overcharging. (Recommended: 18-16AWG copper cable. LC cable not included.)

Smart 3-Stage Charging

Expertly charge your house batteries from the starter battery with three stages - Bulk, Boost, and Float - to achieve automatic and optimal charging up to 100%.

Prolong Battery Lifespan

This product automatically adjusts charging modes based on battery voltages. Its temperature sensor provides -3mV/°C/2V compensation, guaranteeing the most efficient charging even in changing temperatures. Please note that the lithium battery must have a built-in BMS for optimal functionality; an external temperature sensor is not required.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!

Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.
