Redarc BCDC1250D. 12V 50A DC-DC Battery Charger - Alternator & Solar Inputs

REDARC BCDC1250D Charger

This in-vehicle Battery Charger is the next generation in REDARC's DC to DC charging technology, with additional features that make it the most advanced dual battery charger on the market. 
Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1250D will charge from both solar and the alternator simultaneously. With built-in 'Green Power Priority' it will select solar charging first, meaning less load on the alternator. 
Suitable for 12 or 24-volt starting battery systems, the unit will also work with either standard or variable/smart alternators.
The BCDC1250D 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.

Proven and Tested. The award-winning technology in the BCDC has been independently verified and tested to ensure battery life is maximised, charging your battery to a proven 100%. 
Built in Australia and tested for our unique conditions, the DC to DC battery charger will work in the extreme heat of the Simpson Desert, up to 80°C and can handle deep water crossings at Cape York – water, dust and vibration are no match for this charger.

Why use the BCDC1250 over a Voltage Sensing Relay?

1. If the distance between your start and auxiliary batteries is significant, the voltage drop across a long cable run can be enough to prevent your auxiliary battery charging. The BCDC1250 will increase lower voltages (minimum 9V) up to the required charging voltage.
2. The BCDC is also 3 stage charger so it will charge your battery perfectly. Most VSR charging systems only charge batteries up to around 85%.
3. The BCDC1250 will adjust the charging voltage based to the type of battery installed (e.g. Gel / AGM / VRLA).
4. Unlike VSRs, the BCDC1250 will charge 12V batteries from a 24V vehicle bank.
