Flytown Power Co., Ltd Specification of Lithium Polymer rechargeable battery
1. Preface
This document describes the Product Specification of the Lithium-ion Polymer rechargeable battery cell supplied by Flytown Power Co., Ltd 3. Voltage
Single battery voltage is 3.7V/cell, so N pcs pack together in series is 3.7V x N=3.7NV 4. Rating
2200mAh MIN 2100mAh Standard charge: 0.5C Rapid charge: 1C 0.5C CC (constant current) charge to 4.2V/cell, Then CV (constant voltage) 4.2V/cell charge 3.5hours 1C CC (constant current) charge to 4.2V/cell, Then CV (constant voltage) 4.2V/cell charge 3.0hours Approx. 52g/cell Length: 96 ± 0.5 mm (without Tabs) Width: 34 ± 0.5 mm Thickness: 7.6 ± 0.3 mm 5. Battery Cell Performance Check and Test
There shall be no such defect as scratch, flaw, crack, and leakage, which may adversely 5.2 Standard environmental test condition Unless otherwise specified, all tests stated in this Product Specification are conducted at Website: www.flytown-batt.com email: flytown@263.net Tel: 86-760-6268569 Fax: 86-760-8557569 page - 1 - Flytown Power Co., Ltd Specification of Lithium Polymer rechargeable battery
Charging the cell initially with constant current at 0.5C and then with constant voltage at 4.2V/cell (accuracy 4.20 ± N.A. 0.05V)/cell charge 3.5hours. The capacity means the discharge capacity of the cell, which is measured with discharge current of 0.2C with 2200mAh 2.8V/cell cut-off voltage after the standard charge. The cycle life shall be conducted as the following procedures: Step 1:charge the cell with the standard charge Step 2:discharge the cell at 0.5C to 2.75V; Step 3:repeat Step 1 and Step 2 for 500 times. The capacity after 300 cycles is expected to be equal to or more than 80% of the rated capacity. The capacity after 500 cycles is expected to be equal to or more than 60% of the rated capacity. Capacity comparison at each temperature, measured with constant discharge current 0.5C with 2.8V/cell cut-off after Standard Charge shown below. If charge temperature and discharge temperature are not the same, the interval for temperature charge comes to 3 hours. Temperature Dependence of Charge Temp: 20°C Capacity (Discharge) -20°C: 45% 0°C: 80% 20°C: 100% 60°C: 100% Capacity after 30 days storage at 25°C, from Remaining capacity Standard Charge, measured under the same (after 25°C storage) ≥ conditions stated No. 2 6. Mechanical characteristics
Cell (as of shipment) vibrated for 90 minutes for each of the three mutually perpendicular planes with total excursion of 1.6mm and with frequency of 10 Hz to 55 Hz at the sweep rate of 1 Hz per minute. The cell is to be dropped from a height of 1 meter 7. Storage and Others
If the Cell is stored for a long time (beyond 3 months), the cell is to be placed at a dry Any matters that this specification does not cover should be conferred between both Website: www.flytown-batt.com email: flytown@263.net Tel: 86-760-6268569 Fax: 86-760-8557569 page - 2 - Flytown Power Co., Ltd Specification of Lithium Polymer rechargeable battery
