OVERVIEW

Its multi-stage charging algorithm works well for trucking applications such as charging battery banks for tailgate lifters and side curtains. Its design is suited to charge commonly operated automotive 24V battery systems to optimal levels.

Innovative dual battery charger

The DC to DC charger also features a MPPT Solar Regulator, which uses 12V solar panels to charge your 24V auxiliary batteries. It’s compact and fully sealed to block out water, dust, and vibration. The in-vehicle dual battery charger is equipped to handle the roughest roads and rockiest terrains, and is built to work in extreme heat, functioning in temperatures up to 176°F.

Built tough for all conditions

It charges AGM, gel, calcium content, VRLA, and standard lead acid batteries. The durability and reliability of the in-vehicle dual battery charger are benefits you can count on to keep you up and running even during the most tumultuous conditions. The BCDC range charges your auxiliary battery banks to 100% while on the move from one adventure to the next.*

*large capacity battery banks may require a few cycles to fully charge.
