Battery question

[DC2]

I thought the last digit was for form factor (0 being round)

Yeah, that's what I thought too...

After being in the electronics field for 20+ years and using all sorts and sizes of batts for back ups, I've never seen any other shape than round. In the industry these batts are used to build battery packs, now there rectangular, like some laptop batts are filled with these smaller ones. The biggest of this type batt I've seen was for a start up capacitor on an electrical motor, it was a 74950 or 74mm in diameter and 95mm long. If they weren't around $200 a piece I'd try one for a mod.

That is only what I was told. I do know there are square liPo batteries.
