    I made the plunge and fitted the BM Pro BatteryCheck the other day. I would have preferred using the eLite but it was going to be a PITA to fit.
    With apologies to Pearo and Soundman, I accept that I can monitor the battery with a voltmeter and ammeter, but the reality is that in a RV situation it is not practical to:
    1. get the required equipment from the toolbox
    2. unlock and open the caravan front boot
    3. remove the battery covers (which is difficult at the best of times)
    4. take readings
    5. replace battery covers
    6. close and lock boot
    7. pack away tools
    8. wash up
    All in all probably 30 - 40 minutes (longer if it's at night and dark}. After doing this I still wouldn't know how many hours I have left in my batteries.


    BatteryCheck connected to batteries.

    Batteries charging via Xantrex charger on 240V.

    Xantrex disconnected and solar panels covered with blanket to simulate night time conditions. Current draw is because the iPod was charging through 12v circuit and the solar controller display draws some power obviously.

    Back on the Xantrex with all 12v turned off.

    Default An Update

    I've yet do do a trip in the van since the battery monitor was fitted, but I do occasionally go out to the van and turn on different appliances and watch the readings change. When charging via the solar panels it's interesting to watch the current draw and available time change as the sun goes behind cloud cover.

    A very kind friend has tidied up the 12v wiring in the boot of my van so that it doesn't look a birds nest. I've had to modify the battery box covers to accommodate all the wires.
