Self-regulated Charging Mode

The DC-DC battery charger charges your household batteries from the starter battery via a 3-stage charging (Bulk, Absorption, and Float) method, to make sure it optimally and automatically charges to 100%.  

Easy To Switch In Seconds And Prolong Battery Lifespan

Changing chargers is no longer a trouble. With just a simple turn of a switch, you can change among STD, Gel, AGM, and LFP batteries.
*A fully charged lithium battery will accelerate battery aging and affect battery life. Therefore, we adjust the charging voltage in LFP mode to 13.8V according to the charging and discharging characteristics of lithium batteries to effectively extend the battery life.

By utilizing the DC-DC temperature sensor, our charger is able to protect your battery from high or low temperatures by giving -3mV/°C/2V compensation in order to let the charger recognize the voltage more accurately and assure stable & constant charging to the battery.
*The temperature compensation is not to be used with Lithium batteries.

Intelligent Protection

The DC-DC battery charger isolates the input and output which prevents voltage transmission errors and interferes with house battery charging.
It has multi-functional safety technology including over-voltage protection, over-temperature protection, and reverse polarity protection to make it safer for you to use.

Protect Your Batteries

This Leaptrend DC-DC battery charger is compatible with traditional and intelligent alternators.
The D+ Ignition cable is capable of identifying whether the generator is started, to prevent over-discharge of the starting battery and protect the generator.
The LC wire is able to automatically adjust the charging current to prevent excessive charging current from damaging the household battery.
Recommend 18-16AGW or 22-20AWG copper cable.

Please note that D+ Ignition & LC Cables are not included.
