$12 each cell? What is the size, because the biggest I could ever find is 32700 at 7.2Ah. I paid something like $4/cell, but that was before the WuFlu.
Where did the case come from?
The problem I'm having is that the wiring for balance circuits is the opposite polarity of balance leads for external chargers. I have to decide to either wire it for a balance board, or wire it for external charging/cell voltage output, but not both.
I just got a UPS for myself, for Christmas, and am looking to replace the lead acid battery with LiFePO4.
