New 540C-7XL pics dissected,

:p

Yeah, only because I had sized the batt-tray for a 5s2p pack of the TrueRC 8Ah packs, but then decided against it. So, I remade a few of the 3300 packs I already had laying around until I could find something else. That "until I found something else" was longer than I anticipated. Believe me, it's not my ideal choice!

Besides, the M1 cells are quite a bit bigger really; ~4mm wider and ~20mm longer than NiMH cells. They are actually roughly the same size (a little smaller) than my emoli cells and those are a pain to stack in an economical way! I dunno. Maybe if a pack fell into my lap I might try to finagle them in there. I think it would be clunky though...

Oh for sure, i would love a prismatic A123 cell that would safe a lot of space!, The volumetric density is quite low, the gravimetric is high however. They feel very light when you pick them up, for their size that is...

YES, the Europositron battery technology has an energy density 12 times higher than A123 cells, and 10 times more than LiPo!
You would only need a batt the size of one A123 M1 cell to get 15 minutes runtime, HAHAHA, that day will be beautiful!
