Test/Review of Soshine 18650 LiFePO4 1800mAh (Black)
Soshine 18650 LiFePO4 1800mAh (Black)
Official specifications:
Soshine has a series of LiFePO4 cells, this is their 18650 sized one. This is a typical LiFePO4 discharge curve and it looks good. As can be seen the voltage is nearly flat during discharge and then drops very fast when the battery is empty. LiFePO4 has a significant voltage drop when charging stops. Conclusion The cells looks like good LiFePO4 cells, but I wonder about the fairly low current overload protection. There is also the usual limited capacity with this chemistry, it has less than half the energy of a modern 4.2 volt LiIon cell. Notes and links How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries Compare to 18650 and other batteries
