I've switched over to from the Lithium jump packs to using the capacitor style jump starters. The Li-ion work great when new, but they have some weaknesses. First, with regular use they have limited lifespan, the high drain on the batteries...

While I think it would probably work, I'd still replace it. There's a reason the manufacturers put 2 nuts on the stud, it compresses the wire terminal between the two nuts. With your current setup, you're relying on compressing the wire...

It'll most likely work if it's a lithium battery, that's pretty much what those small jumpstarter packs are made of. I wouldn't be too concerned about the electronics as long as the starter battery is still connected, it'll act like a voltage...

Out of all those items I'd put most of the money into the compressor, that's probably the one item you'll be using all the time vs. everything else that might never get used. Traction boards - Never used them, for the price and amount of room...

I'd run a dedicated ground wire because you need to run a + wire to the battery anyway. Running 2 wires is the same amount of work as running 1 and it'll be more reliable and save you a lot of headaches in the future. The DC/DC MPPT controller...
