I currently own, Fenix l1p, Fenix l2p and will soon have a rexlight 2.0 and a jetbeam cl-e. Is there a rechargeable 14500 battery that can be used in all of these lights? If not, Can someone recommend a good rechargeable AA that can be used in all 4 lights? I will also need a decent 4 cell charger. Any suggestions? Thanks.
