Redarc BCDC1250D Dual Input 50A In-vehicle DC Battery Charger
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. 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. 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. This DC-DC battery charger with solar input has been proven to work in all types of terrains, including deep water crossings, and stands up against extreme heat (up to 176 deg F). It's fully sealed against the risk of infiltration from water and dust and 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. Made in Australia by REDARC this amazing range has undergone years of testing in some of the harshest conditions on the planet. REDARC has been in business for 40 years and all of our products are made tough enough to take anything nature can throw at them.

The REDARC 12V 50A Dual Input In-vehicle DC to DC Battery Charger BONUS BRACKET is great in our Solar powered motor home. We will never run out of power now and can run 240 volt items like the laptop through the seperate Inverter

This battery charger works a treat. It allows my primary battery to charge my lithium battery and the lithium runs my fridge etc without draining my primary battery. It also allows both batteries to be charge by the solar panel when camping. Great product!

Have had one of these in my ute as part of a dual battery system connected with solar. It has never missed a beat after 18months or so and still going strong. Highly recommended product.

Works amazing. Charges the Hardkorr lithium battery really fast and super simple to connect the solar.
Great product, excellent value, once again outstanding service
Great product, works as a high quality dc-dc charger should, totally happy with my decision to purchase
This is actually my second 50amp redarc DC to. DC charger. My previous 4x4 had one also. I absolutely swear by them and wouldn't use anything else. Set and forget reliability.
The unit works, hopefully has the current rating as stipulated. Solar input is not efficient with 15 amps in at 19 volts and only putting out 10 amps at 12 volts. Used with 300 watts of solar, 400 amphour battery bank. Easy to install an outback good to deal with.
Autobarn always have sales on and I managed to get this at a bargain price. Redarc are one of the best and trusted brands out there and if you get it fitted by a Redarc dealer you get an extra 1 year warranty thrown in (over and above the 2 year warranty)
Great tech support and phenomenal customer service. I can’t say enough great things about support team. A++++
