When your alternator won't fully charge lithium batteries, this DC to DC charger regulates voltage and current for proper charging. Its 12V and 24V support keeps charging consistent, so batteries reach a higher state of charge.
Factory alternator charging often falls short once a system moves to lithium, especially with variable voltage or limited current control. This unit converts engine power into a proper 4-stage charge with configurable voltage and current from 1 amp to 50 amps. Batteries charge more completely while driving instead of staying partially charged after long trips.
Dual-voltage setups often require additional components just to make different systems work together. This unit supports 12V, 24V, and mixed-voltage systems with an input range of 9V to 35V and adjustable output from 10V to 35V. You can charge across system voltages without adding another converter.
Heat buildup is a common reason DC-DC chargers lose output or rely on noisy fans. This unit operates at 98.5 percent efficiency with a fanless design and maintains full output in high temperatures, with continuous output power up to 104ºF rated at 1,400 watts. Charging stays consistent in confined spaces without thermal drop-off.
Modern alternators can cycle voltage, causing chargers to shut off or reduce output during normal driving. This unit maintains stable input current draw with engine running detection, ensuring charging only occurs when alternator power is available. Charging continues instead of cycling on and off.
Fixed-output chargers limit flexibility as battery banks expand or system demands increase. This unit supports parallel operation and includes Bluetooth connectivity through the VictronConnect app for configuration and monitoring. You can tune performance now and scale output later without replacing the unit.
