Ferei HL50II

This listing is for the headlamp only and not the full kit which normally includes a charger and batteries. We recommend purchasing an external charger found and at least two EVVA 3500mAh batteries for the best performance. The EVVA 3500mAh batteries can be found . For extended runtimes, we recommend purchasing the BA4884 battery case which can be found  as it will allow you to install and use four 18650 batteries for extended runtimes. The BA4884 battery case allows you to swap to a new set of spare batteries or to replace them when they age.
