BACKGROUND:
I've developed a device that helps you add LiFePO4 batteries to your power system.
(emilyandclarksadventure.com/bbms) Since I started selling them, I can't count how many people have asked me my opinion on what would be a good battery to buy. This series is my mission to find you the best, cheapest LiFePO4 battery out there right now.

THE BATTERY LEADERBOARD: Take a look at this link. It leads to a table of all the batteries we have reviewed, looking for that diamond in the rough. We'll keep adding to it.
