I have a Chinese built 6500W generator. The engine is a clone of a Honda GX390 engine. The starter battery is a 12V 12Ah sealed unit like this:

I have a lithium battery booster that I would like to use for starting the generator. This: https://no.co/gb70

The generator battery connections are spade terminals. The booster has the big clamps that you normally connect to a vehicle battery.

The battery booster has a 12V 15A output connector. I don't think that's good enough for a starter motor even on a small engine.

I'm looking for ideas on what to use as an adaptor for clamps to spade terminals or clamps to 10 ga wire. I could put a couple of bolts in a piece of plywood for the clamps and run wire to the battery wires. Looking for ideas for a cleaner solution.

(Yes, I could use the starter rope and forget about the battery. But if you have an electric starter, use it.)
