Shutdown if Output Battery < 4V Charging Algorithm When the BCDC1225 is turned on, it will move into the bulk charging stage called Boost stage. Boost stage maintains a constant current until the battery voltage reaches its set point. The current in Boost stage may vary during operation in order to maintain safe operating temperature, or to limit the difference between input and output voltage. -

Mount the unit to a fl at surface close to the auxiliary battery and away from any heat sources. Wire into vehicle as per the applicable diagram on the next pages, and following the steps below. The BCDC1225 is connected using 6 wires, listed below: • Source Select Blue • Battery Type Orange •... - Page 8 INSTALLATION 1. Wire the ‘Common Ground’ wire to a ground point that is common to both the Start battery (or the Solar Input Ground wire) and the Auxiliary battery to be charged. This point may be on the chassis of the vehicle, on the chassis of the trailer/ camper/caravan or directly wired to both batteries, depending on your installation requirements.

Questions and answers
Will my 1225 select battery type automatically?
@Geoff Zuber the solar selects calcium type battery automatically whereas the 1225 is selecting AGM/gel
No, the Redarc BCDC1225 does not automatically select the battery type. It is designed to charge the auxiliary battery optimally based on the selected battery type.
