Ferei BA4884 Battery Case and Extension Cord

The Ferei BA4884 battery case will allow you to install four 18650 batteries within it and connect it to the HL50II for extended runtime. Once installed you can attach the battery case to your belt or store it in a pocket. The BA4884 is made out of aluminum for extreme durability and is waterproof up to an IPX8 rating. With the ability to change the batteries we feel this is the superior option for extending the runtime on the HL50II or HL60II headlamps. We recommend using the EVVA 3500mAh batteries for the best performance. They can be found
