Hope this doesn't start a whole new argument on the subject, but I seek input from those who may have done this: I'm installing a group 29 deep cycle battery as my main camping battery in my Westy [no, it won't fit under the front seats!] to power my new 12-volt Norcold DC-0040 fridge. Yes, I finally had enough of dealing with the unreliability of the old Dometic! What I'm concerned about is the different charge rate required between the deep cycle and the main battery. The main will likely never be drained below 75-percent, but the deep cycle may become very drained, and often. I currently have a 70-amp relay connected as in the stock Westfalia method for dual batteries. Will that work 'OK', or do I need to use some other method or isolator? It seems to me that the alternator would not charge two batteries of different types and levels of drainage efficiently. Comments? Thanks. Karl Mullendore |
