With many four wheel drivers and people towing a vehicle set up with 2 different battery technologies ( start battery being lead acid ) and the auxiliary battery being another , say AGM or Lithium* , it is difficult to get long life or full charge our of the second/auxiliary battery.*Lithium charge is not supported by this unit when the battery is fitted under bonnet because if the significant increase in temperature there.
The BCDC1225D is a battery isolator and a 3 stage battery charger in one Isolating the start battery with the ignition off and a BOOST , FLOAT* and ABSORPTION charger This unit will also compensate for low voltage wiring to it and the auxiliary battery DOES NOT RELY on the alternator to receive it’s charge rate which in a lot of cases is not the optimum anyway, So if you need more battery capacity from your system consider this as an alternative you may have enough , just the Auxiliary battery may not be getting it’s full charge.This unit also features MPPT ( maximum power point tracking ) solar regulator for connecting in with a solar panel system as well.*Float not applicable on Lithium selection.
In summary the main differences of the new BCDC1225D over the BCDC1225 and BCDC1225LV is
1, Is able to charge common lead acid auxiliary batteries as well as lithium iron phosphate batteries.
2, The BCDC1225D dual input battery charger, charges from solar and DC inputs simultaneously .
3, No external relay is required as with the BCDC1225 and BCDC1225LV.
4, Built in ‘Green Power Priority’ it will select solar first, meaning less load on the alternator.
5, This model is compatible with standard and variable voltage/smart alternators.
6, Due to having a 9-32 volt input range this model is compatible with 12 volt and 24 volt systems .
7, The front panel features 7 LEDs to display the charge profile and charge status.
ABOUT GREEN POWER FEATURE (4)
The Dual Input In-vehicle Battery Charger uses Green Power Priority technology.This means the unit will always supply as much power as possible from the Solar input before supplementing this with power from the Vehicle input, to the maximum output of the unit or required by the battery at the time
