not bad; 3.85 volts on a 40A load.

3.5V on a 100A load in 2P.

True, but I made them to show something else, and I don't feel like going back and redo them to highlight the amps. So you'll just have to squint >..<

The A123s are great IMO, I was getting lightly better results than w/ the 4S packs. They are lower nominal, but 5S~=4S lipo I think.
Only downside is they are heavier than lipos, but they are so tough, long-lasting and safe they are well worth it for everyday driving.

Here's a graph of them put to the limit @ 10S1P. It was a torture test of my system. Blew the whole pack in 7.5min running hard uphill in long wet grass. Packs were 105F at the end. Motor was 110F max.

Man, if that isn't a testament to the virtues of high voltage, I don't know what is. Really impressive Finnster!
