Specification: Condition: 100% Brand New Item Type: RC Accessory Material: Li-polymer Color: As Shown in the Picture Weight: Approx. 93g Battery Type: 850mAh 11.1V 45C Package List: 1 * LiPo Battery Battery Knowledge Cautions: Charging Prevent over heat, flatulence and prolong battery life Charging current: Charging current must not exceed the specified maximum charging current. Charging with a current higher than the recommended value may cause the problem of charge-discharge performance, mechanical performance and safety performance for the battery, and it may cause battery over heat, leakage or flatulence. Charging temperature: The battery cell must be charged within the temperature range of 0-40°C. Recommended charging temperature is 23±2°C. Reverse charging is prohibited. Connect the positive and negative terminals of the battery correctly. Reverse charging is strictly prohibited. If the battery is reversed, the battery will not be charged. At the same time, reverse charging will reduce the charge-discharge performance and safety performance for the battery, and will cause battery over heat, leakage or flatulence. Discharge Prevent over heat, flatulence and prolong battery life Discharging current: Discharge current must not exceed the specified maximum discharge current. Large currents will cause the cell capacity to drop sharply and cause overheating. Discharge temperature: The battery cell must be discharged within the temperature range of -10C-40°C. Recommended discharging temperature is 23±2°C. Storage Prevent over heat, flatulence and prolong battery life The battery must be stored in the temperature range of -20°C-40°C for a long time (more than 3 months) and should be placed in an environment with a temperature of 23±5°C and a humidity of 65±20% RH. Aluminum foil packaging materials are easy to be damaged by sharp parts, such as nickel sheets and sharp needles. Do not use sharp parts to collide the battery. When pick or place the battery, please shorten the nail or put on the glove. The working environment should be cleaned to avoid the presence of sharp objects.
