Fuses or circuit breakers when paralleling batteries are really non optional.
Run each ground wire to a ground block or bus bar. Run each power wire to a fuse and bus the other sides together. The least expensive way is probably the dual level DIN rail fuse blocks if you’re talking fairly low current. You can also get multiposition fuse blocks for ATC style blade fuses, Duracomm makes some, you can also find them at auto parts stores. Personally I like DIN rail circuit breakers which also make a convenient disconnect switch, but yes they do cost a bit more.

Maybe I don't understand.... I would lean towards the standard of fusing between paralleled batteries though. At least with large-ish batteries that can dump enough current from a good string to another with a shorted cell and burn up your wiring, which pretty much acts as a fuse itself, but still. For short #10's, I would put a 40A fuse. I believe APC used 50 or 60A fuses with #10. That's kinda scary. On 5/10/2016 12:51 PM, Josh Luthman wrote: That's pretty neat!

Any suggestions or parts to get two leads on the F terminals? http://i.imgur.com/r3X21cw.jpg My only idea right now is to solder the wires together near the terminals and then tape/wrap it.
