The REDARC BCDC1250D is a 12V, 50A In-vehicle DC to DC Battery Charger designed to keep your auxiliary battery charged when driving or with portable solar panels when parked. It uses multi-stage DC-DC charging, a system that allows optimum charging levels for your auxiliary battery. It is solar ready and suitable for many battery types including lithium, AGM, GEL, standard lead acid and calcium.
Dual Battery Charger with solar input
The BCDC1250D has been developed to provide a higher current output, it features an additional charging stage known as SoftStart which has been engineered so that it can handle more demanding applications.
For installation, we recommend also purchasing the REDARC FK60 60amp fuse kit.
Multi-stage charging profile
Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1250D will charge from both solar and the alternator simultaneously. And, with built-in Green Power Priority it will select solar charging first, meaning less load on the alternator.
Suitable for 12 or 24-volt vehicle systems, the unit will also work with either standard or variable/smart alternators.
It is compatible with all common types of batteries used in automotive and recreational vehicles such as AGM, Gel, standard lead acid, Calcium and LiFeP04.
As a guide, the BCDC1250D is used for battery bank sizes over 200AH. For smaller batteries of 75-200AH, REDARC recommends the BCDC1225D.
Built tough for all conditions
This DC-DC battery charger with solar input has been proven to work in all types of terrains, and stands up against extreme heat (up to 176°F). Protected against water and dust, it will hold up to the adventure at hand. It's designed to maximize the performance and life of your auxiliary battery and is suited for battery bank sizes of 200AH and above in most applications.
