Product Description

Li-18650-3S1P-11.1V 2600(2500)-PCM-
The 18650 battery pack is one of the most popular lithium-ion battery packs available today. Powered by the 18650 battery, it is very reliable and boasts an excellent cost per kilowatt hour.
The 18650 battery pack is commonplace for consumer electronics, electric vehicles, and energy storage systems. It can be found in medical devices, robots, industrial instruments, military equipment, and more. A custom 18650 battery pack may include battery holders, a PCB, PCM, BMS, cell balancing board, or other components.
Note: The voltage of li-ion cells is 3.6V—but some misleadingly mark cells as 3.7V. This causes battery pack ratings of 11.1V (3S), 14.8V (4S), etc.—instead of 10.8 V(3S), 14.4V (4S) etc.

Product Electric Performance Test 




Test Conditions



Capacity retention

Fully charging, store them at (20±5)℃ for 28 days, then discharge to
8.4V @0.2C.(the residual capacity is above 85% of nominal capacity)

Discharging time4.25h


Cycle Life @25℃

Discharge to 8.4V @0.2C, then Charge the battery @0.2C to reach 8.4V. Then charge the battery at constant 12.6V voltage until the charging current decreasing to 0.02C. Rest for 10 min. discharge to
8.4V@ 0.2C and rest for 10 min. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity.

Cycles life ≥300



Charge the battery to 40%~65% of its rated capacity using standard charging mode, then keep it in an 20℃±5℃, humidity 45% ~ 85% room for 12 months, fully charge and discharge it @0.2C until voltage down to 8.4V.
(The testing sample should be within 3 months dated from production date)

Discharge time≥4h

 Mechanical Performance 



Testing method



Vibration Test

After standard charging, put battery on the vibration table. 30 min experiment from X, Y, Z axis. Scan rate: 1oct/min; Frequency 10- 30Hz, Swing 0.38mm; Frequency 30-55Hz, Swing 0.19mm.

No influence to batteries' electrical performance and appearance.


Drop Test

Random drop the battery from 1.0m height onto wood board 6 times.

No explosion or fire
