This Golisi cell performed a lot better than the iJoy 40A 3750mAh 21700, especially at higher current levels, but it is overrated.
I haven’t compared its performance directly against the popular 20700’s and 20650’s but will be doing a shootout with all of them soon. I don’t know which cell Golisi is wrapping for this 21700.
This Golisi is badly overrated at 40A but is a true 30A cell, running just slightly hotter than the average of other cells at their rating. This can be handled by just rating it at 29A but this cell is within the acceptable temperature range for a 30A rating.
The wrap says “IMR 21700” but I’m pretty sure this cell doesn’t use the chemistry associated with the IMR model number prefix.
This cell delivered 3714mAh and 3822mAh in my capacity tests. Since the rating must be lower than what any cell delivers it’s not quite a 3750mAh cell.
I am rating this Golisi S35 at 30A and 3700mAh.
Two cells were donated for the purposes of testing by Golisi (www.golisi.com). Thank you!
