I've made a dumb move. I'm building a controller for a smaller application - a VW Beetle running at 96V with a 7.5" salvage forklift DC motor. I substituted 150V Mosfets and dropped down on the power caps' size to 470 uf. I messed up and ordered 30 mm diameter caps, though (only cost $20 instead of $60 for the 820 uf's !) so all sixteen won't fit. I can stuff thirteen of them on the power board by changing the hole pattern.

My question: Do you think (13) 470ufs will be OK - they should fit OK like the pic below - or should I spring an additional $60 and get the 25mm dia 820 ufs?
