So I'm thinking in the first wave of searching, 8 of these should meet those requirements. Hooked up in parallel should give me 24AH.http://www.batteryjunction.com/ultrafire-brc-18650.htmlI'm still looking for smaller or flatter, but those are a good first round pick i think.
These fully protected cells simplify usage with their integrated PCB. Perfect for your single cell application these cells are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell. If you are building a pack please choose one of our other cells and the appropriate PCB.
So just to make sure I'm understanding this, if I use something like this:https://www.sparkfun.com/products/8483and hook up say, 10 of them, in parallel, then a single charge circuit would be sufficient? I'm also looking at several of the 18650 style batteries, quite a capacity to reach, I'm trying to get around 20AH at a minimum, but reaching the goal would be even better.
