LingsFire® BaoFeng 7.4V 3800mAh Li-ion Battery For Two Way Radio Interphone Transceiver Walkie Talkie UV-5R UV-5RA Series + Car Charger
Eh, it's okay. Says it is for the UV-5R et al, but I had to do some carving to the case to make it fit the radio (does not fully seat) and the charger is quite rickity. Battery life is impressive though!
