So I bought two 12V 100Ah batteries to replace the AGM's that just never lasted long enough. Always needed to be recharged by the generator.
Unfortunately the camper was stored somewhere I couldn't easily access it. Then my dad bought a storage unit for RV's and cars and shit so I have a nice air conditioned space to work on it.
I e-mailed the company and asked "exactly what model charger do you use in this model camper?" and they told me Progressive Dynamics. So I got the Progressive Dynamics lithium charger hoping for a direct swap. Nope, they used NOCO chargers for a period of time and this camper is one of them. So I can work around that but what to do with this wiring mess? I really don't feel comfortable just putting all this on the lithium batteries...I'd probably have to get longer M8 bolts anyways because I'm actually going to be using real compression lugs and real 2 AWG Windy Nation cable (would have gone for something a little thinner but the 2 AWG is leftover from the other camper that's had 6 AWG and could potentially pull 120A if someone tried to use the air conditioning on the lithium batteries in there....so that needed an upgrade.)
Do I buy a 12V fuse block and properly run everything through a fuse block? Should I run the two batteries to some simple bus bars and then run a single positive and negative to the Progressive Dynamics charger? I'm not too wild about daisy chaining the batteries in parallel. If I go the bus bar route should I just run all the loads off the bus bar? Some of them already have built in fusing.
Bus bar route seems the best way to go. And yes I'm aware the Amazon ones can be junk. Loads on this are pretty small. The charger is a 45A model and I think thats the largest amount of current any one single device will be sending through the bus bars.
