6600mah 6.4 Volt Lifepo4 Li Ion Battery IFR26650 For Emergency Lighting


Product Parameters

Product performance:

1.High energy density: LiFePO4 batteries have a high energy density, allowing them to provide higher energy output.

2.Long lifespan: Compared to other lithium-ion batteries, LiFePO4 batteries have a longer lifespan due to their high cycle life.

3.High discharge rate: LiFePO4 batteries can provide high power output in a short period, making them suitable for applications that require high energy density and high power output.

4.Low self-discharge rate: Compared to other batteries, LiFePO4 batteries have a low self-discharge rate, allowing them to maintain their charge for a longer period.

5.High safety: LiFePO4 batteries are relatively safe compared to other lithium-ion batteries, as they are less likely to overheat, explode, etc.

6.Environmentally friendly: LiFePO4 batteries are environmentally friendly as they do not contain toxic heavy metals and have a small impact on the environment.

7.Good high-temperature performance: LiFePO4 batteries perform well in high-temperature environments and are more tolerant of high temperatures than other batteries.

8.Low internal resistance: LiFePO4 batteries have low internal resistance, allowing them to provide high current output in a short period, suitable for applications that require high power output.

LiFePO4 Battery Performance and Test Conditions

1. Standard test conditions

Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.

2. Standard Charge/Discharge

Standard Charge: 0.2C

Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 14.6V. The battery shall then be charged at constant voltage of 14.6 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.05CA. Charge time: Approx 7.0h, The battery shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.

Standard Discharge: 0.2C

Battery shall be discharged at a constant current of 0.2C to 10V @ 20º ± 5C
