Charge Your Secondary Battery from the Vehicle's Alternator Charge your secondary or auxiliary battery from the vehicle's alternator. Suitable for 12V or 24V vehicle setups and compatible with standard or smart alternators. Lithium BMS Sleep Mode & Recover Feature When in Lithium Mode, if the voltage drops below the safety parameters of the lithium battery, the DC/DC charger will enter recovery mode. The DC/DC charger will trickle charge the battery until it reaches the cut-in voltage and is able to start normal charging cycles. New Connection + Backwards Compatibility Take the hassle out of connecting your DC/DC charger. Run your positive alternator, negative ground and ignition wires together with the new three pin Anderson connection. It is also compatible with common two pin Anderson connectors, allowing for a normal positive and negative wire connection if the ignition wire is not needed. Welcome to the next generation of DC/DC vehicle battery charging. We have developed and delivered an onboard vehicle charging solution like no other. Engineered for durability and expertly designed for charging performance, this charger is the new weapon of choice in dual battery systems. The True 4-stage charging features BULK, ABSORPTION, FLOAT and PULSE modes with advanced algorithms enhancing the overall charging performance of auxiliary batteries. This ensures your auxiliary battery is charged the correct way enabling it to reach maximum charge capacity while also optimally maintaining the battery. When coupled with the powerful 25 Amp maximum output capability, it provides exceptionally fast and effective charging. It provides the reliable charging output required to charge, maintain and and prolong the life of your auxiliary battery, in new and old vehicles. Inbuilt isolation prevents your auxiliary battery from draining your start battery when your vehicle is not running or charging. The smart tech of our charger detects the charging status automatically, so you never need to worry about engaging or isolating batteries manually. It’s all managed for you from the moment you turn the key. Welcome to the next generation of DC/DC vehicle battery charging.
