Liitokala 21700 li-lon battery 4000mAh 3.7V 15A discharge rate power 10C ternary car lithium Electric battery+DIY Nickel | Электроника

21700 theory for the life cycle of the battery lithium battery charging 1000 times. commonly used in lanterns, headlights, mobile medical equipment and so on. can also be combined, but also with the difference between the board and not with the board, the main is the board with over check protection to avoid loading out of date, or the battery is very clean and lead to scrap battery . mobile phone charger this month should be available, that is, portable cargo type at any time, should be able to meet the general needs of cargo customers. and this mobile phone charger is universal Oh! Mobile interface too! Battery Usage and Precautions】 【Lithium 1, do not use non-lithium battery charger 2, never in excess on 3, the standard voltage of 3.6-3.7 V lithium battery, after charging the voltage has reached 4.2 V, set the voltage is 2.75 V. 4, long-term non-use stored recommendations fully charged, and charged once every six months. 5, this battery has no memory, you can always feel free to charge. 6, the minimum temperature of the battery-20 degrees above, the maximum temperature is 50 degrees. 7, long-term (more than 3 months) do not use the lithium battery, should be charged 50% of the power to save. 8, due to different batches of different periods of the factory using different raw materials, batteries may exist before the purchase of batteries is blue, the purchase of red, a normal phenomenon, each of the batteries were tested before leaving the factory, feel be free to use. 1 Cellular / Cellular Specification Product Specifications At the. items / items Specifications / Specifications Note 1 Nominal capacity 4000 mAh download 0.2C Standard 2 Minimum capacity 3950 mAh 3 Rated voltage Q 3.7 V Average Operating Voltage the working voltage 4 delivery voltage 3.85 ~ 3.90 V within 10 days from factory in the factory within 10 days 5 a Load voltage 4.2 V ± 0.03 V by the standard load method 6 standard loading method 0.5C constant current, 4.2V constant load voltage to 4.2V, continue charging until current decline of ≤ 0.01C 7 load current recharge current 0.5C 2000mA standard charge, charging time about 3 h (Ref) standard charge, about 3 hours (for reference) 1.0C 4000mA Quick charge, charging time about ::: 2 h (Ref) fast charge, time is about 2 h (for reference) 8 standard discharge method standard discharge mode constant current discharge 0.2C to 3 V,
