Test/review of LFP18650E 1500mAh LiFePO4 (Violet)

LFP18650E 1500mAh LiFePO4 (Violet)

Official specifications:

  • Voltage: 3.2V (limit voltage:2.0-3.65V)

  • Capacity:1400-1500mah

  • Cycle times: about 800

  • Brand new Lithium Ion batteries,used for laser pointer,torch flashlight,and other electronics.

  • Size:18650 battery (18*65mm)

  • Max discharge current: 2-3C (Continous discharge 1-2C)

  • Max charge current: 1C

This is LiFePO4 batteries, they have lower voltage and another discharge characteristic than the usual LiIon batteries.

These types of LiIon have a very flat discharge and considerable less capacity than normal LiIon batteries.


These batteries looks like good LiFePO4 cell with rated capacity.

That’s interesting. I see your source is AliExpress. Any idea who makes these cells?


Well, thanks for testing them anyway. Perhaps LiFePO4 will one day be a good choice for direct drive lights with very low Vf emitters. Of course, they won’t push the LED as hard as a Li-Ion would. But then, that would be a good reason to do it.
