Just use a bunch of the deans bulb dischargers they are 30 amp loads with 10 #1157 automotive lightbulbs. Wire a bunch in series and watch her glow. Kinda old school use to use them for ni-cd's and ni-mh packs but good size load for not much cash and real simple.
I'm apt to do it, I would love to see 75C from that pack over and over again. Parts ordered!
