IFR32700 6000mAh LFP FB Tech Cell, Model Name/Number: IFR32700/18650, Capacity: 2500 Mah

After standard fully charge, cell shall be attached to a vibration table directly and subjected to vibration that consists of 10 Hz to 55 Hz to 10 Hz at the speed of 1Hz/min in 90~100mins.The total excursion of the vibration is 0.8mm(0.060 inches). The cell shall be vibrated in each direction along axis of the cylinder and the vertical directions of axis of the cylinder. The cell is discharged following the standard discharge method. Apply a 5V power supply and a 3C charge current for 1.5hrs.The cell is charged following the standard charge method. After charging the cell is put in the oven. And then the oven temperature will be ramped at 5 per minute to 130 and held at 130 . When the temperature of the cell reach 130 , the cell is maintained in the 130 oven for a maximum of 60 minutes or until a fire or explosion is obtained, whichever comes first. Record the time that the cell temperature reaches 130 and the time when a fire or explosion occursAfter charging a cell following the standard charge method, the cell shall be crushed between two flat surfaces. The direction of the crushing force shall be vertical to axis of the cylinder. The crushing force is to be applied by a hydraulic ram with a 32mm diameter piston. Crushing force is approximately 13 KN. Once the maximum pressure has been obtained it is to be released.Specifications:Internal resistance: ≤60mΩVoltage at Storage and transport: 3.6V-4.0VCharging Temp Range: - 0 45 Discharging Temp Range: -20 60 Storage Temp Range: -20 45 Positive and negative: - +: Cover, - : CanStorage humidity: ≤90% RHDischarge rate capability:Cap(0.5C)/Cap(0.2C)≥95%Cap(1.0C)/Cap(0.2C)≥90%Cap(2.0C)/Cap(0.2C)≥80%High-Low temperature discharge performance:Cap(-10???)/Cap(25???)≥70%Cap(0???)/Cap(25???)≥85%Cap(60???)/Cap(25???)≥95%Storage performance:Residual capacity / Original discharge capacity ≥80% Recover capacity / Original discharge capacity ≥85%
