VIFLY StoreSafe Smart Lipo Battery Discharger XT60 XT30 with Heatsink for 2-6S Lipo Battery VIFLY StoreSafe is a smart lipo battery discharger that can intelligently discharge your battery to storage voltage.With built-in advanced algorithm and the temperature sensor, it can keep the highest discharge rate in an appropriate temperature range.The heatsink would effectively dissipate the heat to prevent the discharger from overheating. Intelligently Discharging LiPo Battery to Storage Voltage Never keep your battery at the full voltage considering the safety issue and battery life. VIFLY StoreSafe would be the best solution to discharge and maintain your lipo batteries. With the advanced algorithm and built-in temperature sensor, VIFLY StoreSafe lipo battery discharger can intelligently adjust the discharge speed according to the battery voltage and unit temperature. It ensures the highest discharge rate in an appropriate temperature range. Heatsink to Cool Down the Discharger In addition to the built-in temperature sensor to control the unit temp, the heatsink would effectively dissipate the heat to prevent the discharger from overheating. Automatically Identity 2S to 6S Batteries VIFLY StoreSafe lipo discharger can be compatible with 2S to 6S batteries. When plug in, VIFLY StoreSafe would recognize the battery type automatically, no need to do any extra setting to select different battery types, so simple and convenient. Operation: Before using StoreSafe, please make sure that the voltage of each battery cell is higher than 3.95V. After plugging in the battery, the LED that indicates the status will flash for about 5 seconds and then enter the discharging state. If the LED status not indicates correctly, please disconnect the battery immediately. The StoreSafe will stop discharging when your battery reaches storage voltage (3.85V±0.08V / cell) and then goes into an ultra-low leakage current(
