Diamond HV Semi-Solid-State Li-ion Battery features high energy density, high discharge rate, low-temperature resistance and high safety performance. It supports max 15C discharge rate and can still achieve 96% discharge rate even at -20℃. Diamond HV series semi-solid-state li-lon battery has a higher voltage charge per cell to provide more power for the UAV and largely improve the flight time. AYK-250 using 2* 6S 32000 mAh or 1* 12S 32000 mAh has 30 min longer flight time than that using 2* 6S 25000 mAh. Diamond HV battery is suitable for UAVs or other electrical equipment that requires long endurance time such as AYK 250, AYK 320, etc. Highlights: -High Discharge Rate -4.45 V Per Cell -285 Wh/kg Energy Density -1000 Times Cycle -Lowest -40℃ Working Temperature
