I'm building a portable LiFePO4 100aHr battery. I want it to have 3 barrel plugs that support up to 5a each. I'd like them all wired to the same on/off switch. Do i take all 3 positives, combine them together and bring them to the switch? And then run one wire from the switch to the fuse block? I'm guessing I should use a 15a fuse (3 x 5a) but not sure. Any input appreciated. Thanks!
