This is a high current 26650 cell, the two ratings printed on the cell is continuos and pulse rating.
The discharge curves is tracking nicely and capacity is nearly constant up to 20A and do also match the marked capacity. The 30A curve is a bit high for the battery.
Conclusion
This battery has good high current performance, this also means it is not a top performer in capacity.
Notes and links
The batteries was supplied by Windyfire for review.
I would like to try some of the good ones for obvious reasons suchas price. But, I have been afraid to order them and have stuck with Efest, Keeppower and Olight. I use 18650’s, 18350’s and would like some 16340’s.
yes our Web site personnel have mistake ,the windyfire 26650 3500mAh is not LIFePo4 battery ,it is Li-Mn battery ,the voltage is 3.7v(LIFePo4 Voltage is 3.3V) .
Hi wolfdog1226 ,nice to meet you here.
may i ask you one question ,Based on my experience,the minicree flashlight Conventional drive current is generally 0.5A,windyfire 14500 battery the discharge is 10A,the li-ion 14500 Usually have 2-4A discharge ,so the IMR 14500 and the li-ion 14500 all can Can meet the driving current ,In theory is the same output, I do not know how is the Real world ,
wolfdog1226 ,do you have some experience.
