Lithium Iron phosphate (LiFePO4) batteries are a type of lithium ion (Li-Ion) rechargeable battery. Their benefits over the more traditional cobalt-based Li-Ion batteries are increased power output, faster charging, reduced weight and longer lifetime. The batteries also have better safety characteristics and do not explode under extreme conditions. LiFePO4 batteries also eliminate the concerns of cobolt entering the environment through improper disposal once they have expired.
