When your alternator won't fully charge lithium batteries, this DC to DC charger regulates voltage and current for proper charging. Its smart alternator support keeps input stable, so batteries reach a higher state of charge.
Factory alternator feeds often leave lithium batteries partially charged or cycle unpredictably with modern smart alternators. This unit regulates input from 9V to 17V and delivers controlled output with adjustable voltage and current from 1 amp to 50 amps. Batteries charge consistently while driving instead of sitting below full capacity.
Many DC-DC chargers rely on fans and lose output in confined spaces due to heat buildup. This unit operates at 98.5 percent efficiency with a fanless design, maintaining full output in enclosed or high-temperature locations. Charging stays consistent without added noise or thermal throttling.
Simple charging setups fail to adjust for battery state, leading to incomplete charging or long-term battery stress. The adaptive 4-stage algorithm adjusts charging behavior based on shallow or deep discharge. Batteries reach proper charge levels and maintain better long-term performance.
Variable voltage alternators can cause chargers to cycle on and off or reduce charging effectiveness. This unit maintains a stable input current draw with engine running detection, ensuring consistent operation with Euro 5 and Euro 6 alternators. Charging continues instead of dropping out during voltage fluctuations.
Fixed-output chargers limit flexibility when battery systems or load demands change. This unit allows voltage and current adjustment and supports parallel operation to increase total output. You can tune performance now and expand capacity later without replacing the charger.

Ratings & Reviews
These are a great addition to your Off Grid electrical system. We design and install systems with them all the time at Atlanta RV Center along with other Victron components like Multiplus inverters. With professional design and installation this will keep your batteries charged while driving between stops on your adventure.
The converter is awesome. The engine shut down detection works perfectly on my Sprinter. My battery stays charged up and is easily verified by the app.
