Specification: Condition: 100 Brand New Item Type: RC Accessory Material: Li- Color: As Shown in the Picture Weight: Approx. 93g Battery Type: 850mAh 11.1V 45C Plug Type: JST Plug Package List: 1 * Battery Battery Knowledge Cautions: Charging Prevent over ht, flatulence and pro 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 -dis performance, mechanical performance and performance for the battery, and it may cause battery over ht, lkage or flatulence. Charging voltage: Charging voltage must not exceed the rated voltage of 4.2V cell, and 4.25V is the highest limit of charging voltage. The design of should meet this condition.When voltage of battery is higher than the rated voltage, the battery may cause the problem of  -dis performance, mechanical performance and performance for the battery, and it may cause battery over ht, lkage or flatulence. Charging temperature: The battery cell must be d within the temperature range of 0-40C. Recommended charging temperature is 23+-2C. 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 d. At the same time, reverse charging will reduce the -dis performance and  performance for the battery, and will cause battery over ht, lkage or flatulence. Dis Prevent over ht, flatulence and pro battery life Discharging current: Dis current must not exceed the specified maximum dis current. Large currents will cause the cell capacity to drop ly and cause ove ting. Dis temperature: The battery cell must be dis d within the temperature range of -10C-40C. Recommended discharging temperature is 23+-2C. Over-dis : It should be noted that during the -term unused period of the battery, it may be in some over-dis state with other self-dis characteristics. To prevent over-dis , the battery should be periodically d to maintain its voltage between 3.6-3.9V. The should be configured to prevent the battery from discharging below the specified cutoff voltage. In addition, the should be configured to prevent recharging. Step: Before the battery is quickly d, it should be pre- d for 15-30 minutes with a small current (0.01C), so that the voltage of ch cell rches 3V or more, and then it quickly. This pre-charging step can be implemented with a timer. If the voltage of the (individual) cell has not risen 3.0V within the pre- pre-set time, the should be able to stop the step of quickly and show that the cell/battery is in a abnormal state. Storage Prevent over ht, flatulence and pro battery life The battery must be stored in the temperature range of -20C-40C for a time (more than 3 months) and should be placed in an environment with a temperature of 23+-5C and a humidity of 65+-20 . Storage voltage is 3.6V-3.9V. Aluminum foil packaging materials are sy to be damaged by parts, such as nickel sheets and needles. Do not use parts to collide the battery. When pick or place the battery, plse shorten the nail or put on the glove. The working environment should be clned to avoid the of objects.
