Ours was on the engine side of firewall. Brought in the 7.2ah backup battery. It was getting unreliable and I found a way to eliminate it. now just use a switch on the EXP bus panel to bring in the E bus battery and SD8 alternator.
Thanks Guys. I like the idea of a switch instead of a relay but I think the whole point of using the relay was to get the power line that you could not shut off out of the cockpit right?

That is my reasoning on unprotected circuits. Would I rather have a relay fail(that can be bypassed to get me home) or burning plastic, sparks, smoke and molten copper produced during a crash?

I used a switch. The line coming from the battery bus to the E-bus switch is fused on the battery bus so that is not a cabin worry. The line from battery, through the firewall, to the battery bus fuse block was a worry until I put a fusible link on it at the battery post. Fuse link recommended by an AI that I asked to give me a once over prior to first flight. I agreed.
