ok Mark.

seemed like a lot, but I believe you :)  but 400 A for 1/2 sec is not
really enough time to start the engine is t?

I had a cursory look this morning and found there is a sure power
1315-200 that is explicitly rated for battery "bridging" for starting
(220 A cont).

The manufacturers spec of the relay used in the 1314/1315 is 400 amps
for up to 1/2 second after the relay closes, also known as inrush
current. I have found the relay to be more robust than the spec says but
YMMV. Since SurePower says their product supports starting boost I would
assume they have determined that the relay can do it.
