FAQs About This Product

Ask a Question

  • I live off the grid and have 32 deep cycle batteries charged by solar panels, seasonal hydro and a generator. My system is 48V with Magnum inverters. Do you have anything like the XC100-P that would work to increase battery life?

    48 volt Series DiagramIt sounds like you want to prevent / remove the debilitating effects of sulfate in your batteries and would be best served with an on-board desulfator.

    The size of your battery bank may be best served by using 1 of 2 methods. A 36-48V High Powered Industrial Desulfator (BLS-36/48-Multi-F) made by Battery Life Saver or by breaking your system down into multiple sub-series and use the 12V or 24V units.

    Example a 48V system utilizing four 12 volt batteries could use four 12V Power Pulses or two 24V Power Pulses or one 48V unit.

Product's Review
It appears to be working fine. I connected my Battery Minder 2012 to it and it kept charging for 24 hours. The two batteries showed 13.55 volts so I disconnected the 2012. The OBD-12 kept working until the voltage dropped some. I don't know the voltage it stopped pulsing at.
