Hello,
Thanks for all the help everyone has given me in all my rambling threads :) you are all awesome!!!

I have VSR I took from a van I had many years ago and fired it into my new van, I'm pleasantly surprised that it is a dual flow type.


So when I plug in the van to charge up my leeeesure batteries it also charges my van battery.

My question, is this cool in the long run? does the voltage level out between the batteries and when the leeeesure batteries are full will it stop the charge. Then essentially they all drain down to like 12.6 and the relay opens and stops the feed. With dual flow vsr's do they just feed the van battery and it's harmful, should I maybe put an isolator switch on the van side so when I plug in at a hookup site it doesn't feed into the van battery as I've been driving for 3 hours and already charged the leisure batteries at home and also the van battery.

I hope that all makes sense. Basically am I damaging my van battery with a constant feed when charging the leeeesure batteries.
