That's a good point on the KOEO stuff, with the big block in the car I would in the heat run the fan + water pump for a few minutes when coming back into the pits.
Looks like a comparison of Reserve Capacity is the ticket for that?
Red top has 90min (yellow would be more)
a 'larger' Braille 147-B14115 has 25min, so that's a considerable difference.
Saving the footprint is what I'm most after - to either run a charge pipe between the battery and rad or for placing a w2a intercooler over on that side.
