treebark Report post Posted December 9, 2017 We have a 2015 Winnebago/Itasca Cambria. In between camping trips we store it where I can plug one electrical extension cord. Our RV has three(3) batteries. One(1) for the Engine and two(2) batteries for the house. Are the two systems isolated? If I connect an electrical two-way Y adapter, is it OK to charge the two battery systems with separate chargers, powered from the same cord? Thanks Share this post Link to post Share on other sites
wolfe10 Report post Posted December 9, 2017 treebark, Welcome to the FMCA Forum. Most coaches charge the house battery bank from the original equipment converter or inverter/charger. Easy to verify with a voltmeter. Check voltage before plugging in and then after plugging in. Most coaches do not charge the chassis battery from this charger. Again, verify with a voltmeter. And absolutely no problem if you find that the chassis battery is not charged to use a SMART small charger to keep that battery charged. Share this post Link to post Share on other sites
