Proper Balance of wiring 3 12V batteries
I have read a lot here on the importance on wiring additional batteries properly (thx pianotuna). I'm looking to wire 3 12V T1275 in parallel, and looking for how other's have physically connected 3 ...

With thirteen positive wires all trying to be on one buss, you might need two or three sub-busses to hold all the terminals. That's what I do. I collect a few pos ring lugs and bolt them together with a short fatter wire out from that going to another fatter wire that comes from another collection of smaller wires. Those two go on the buss that the battery links all go to.
Fusing starts with a big amper on the first fat wire to a branch buss, then each thinner wire from that has its own smaller amp fuse.
The pos wires from each battery to the buss point could be unprotected and everything (except the breakaway brake wire) from there would be fused, each in its own way, depending on its wire size and current load. Or you could fuse each battery link with a smaller amp fuse instead of using a big amper for all three at once.
The inverter pos to that buss point would have a big ANL and the converter wire might have a 60a resettable Dc circuit breaker. The slide and jacks already probably have 30a fuses and the 7-pin charge wire might share one of those already or have its own. Solar pos from controller has own or might share with converter's. The Trimetric has its own little fuse too--forgot that one above so now its eleven positives. Add the LP alarm and the stereo, for thirteen.
