[Snipeye]

Here's a thread for people to post what they feel are the best batteries for portabalizing! This will be for pre-made batteries/chargers that are easy to canabalize. I know theres a forum dedicated to things like this, but its burried so deep, i dont thonk many people see it. I'll post an example:

Model: BP-511
mAh/$0.01: 3.63
mAh: 2200
$/Battery: 6.06
Cons: Bought in packages of 2
