This kit includes two Kastar BP-950GPro professional lithium-ion batteries (7.4V, 5800mAh, 42.9Wh) and a Kastar LCD Dual Fast Charger. Each BP-950GPro battery charges via Micro USB using a 5Volt 2A adapter and features a 4-LED indicator to show remaining charge at a glance. The cells also provide a 5V 2.1A output so the battery can serve as a power bank for charging external devices — convenient for both wall charging and on-the-go use. The included Kastar LCD Dual Fast Charger accepts 110-240V worldwide input and can charge batteries with voltages from 6.8V to 16.8V regardless of capacity. Its LCD clearly displays charging status and battery capacity, and the dual slots allow two batteries to be charged simultaneously. An onboard MCU automatically detects battery voltage and manages intelligent charging to prevent overcharge. Charging is performed using CC/CV control for reliable, efficient operation, and the unit offers pre-charge and Li-ion 0V activation functions to help extend battery life. The charger also supports changing plates for compatibility with a wide range of digital batteries.
