The in-vehicle battery charger, or BCDC, keeps the auxiliary battery charged whilst driving, ensuring your secondary battery is charged to a proven 100% no matter its type or size. The Dual Input range incorporates an MPPT solar regulator, allowing you to charge from solar panels and blankets, lessening the load on vehicle alternators. The DC charger uses a multi-stage charging profile to ensure auxiliary batteries are charged to 100%, whereas a Smart Battery Isolator will only ‘top up’ the secondary battery as it focuses on the state of charge of the primary battery. In a dual battery setup where one battery is used as a starter battery to operate the vehicle and one as a secondary to run electrical devices, you need a BCDC. It offers greater flexibility for your dual battery setup, not only in terms of correct charging for your specific battery, but also suitability for different alternator types, installation location, and battery size.
