All in Charge

The Leaptrend Altair Series 40A 12V DC-DC Battery Chargers are the most effective way to charge your house batteries from the starter battery. For additional safety, it isolates the input from the output preventing incorrect voltage transmission. Easily install the compact yet sturdy DC-DC battery charger on RVs, commercial vehicles, boats and yachts, and accommodates many types of batteries on the market, including lead-acid batteries, lithium batteries, lithium iron phosphate, etc.

Self-regulated Charging Mode

With three stages of charging (Bulk, Absorption, and Float), the DC-DC battery charger will charge your house batteries from the starter battery to ensure that they are charged to 100% automatically and optimally.

Easy To Switch In Seconds And Prolong Battery Lifespan

Our battery charger is suitable for various batteries. 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, this charger can bring extra protection for your battery from high or low temperatures by giving -3mV/°C/2V compensation so that the charger recognizes the voltage more accurately and assures stable and constant charging to the battery.
*Caution: Please note the temperature compensation is not to be used with Lithium batteries.

Intelligent Protection

The DC-DC battery charger isolates the input and output to prevent voltage transmission errors and interfere with house battery charging. We adopt a 3-in-1 protection method including over-voltage protection, over-temperature protection, and reverse polarity protection. It ensures safety while using.

Protect Your Batteries

This Leaptrend DC-DC battery charger is compatible with traditional and advanced alternators.
The D+ Ignition cable can identify when the generator is started, in order to prevent over-discharge of the starting battery and protect the generator.
The LC wire can automatically adjust the charging current to prevent excessive charging current from damaging the house battery.
Recommend 18-16AGW or 22-20AWG copper cable.

Caution: the D+ Ignition & LC Cables are omitted.

Great supplement to RV solar

Finally! Finally I have power while I drive going to my RV battery. I have always relied on just solar but that’s not always a guarantee. Easy install, added a on/off switch so I can turn off the vehicle 12v so it turns off if I want. Thanks Leaptrend!

Bought a month ago and so far it works great. Just what I needed to keep my secondary battery charge on my truck and topped off.
