This Vapcell appears and performs identical to the great performing Sanyo NCR20650A.
The Sanyo NCR20650A has a “rated” capacity of 2900mAh, a “minimum” capacity of 2950mAh, and a “typical” rating of 3100mAh. So while I always try to use just the rated capacity for a rewrapped cell for my ratings, 2900mAh in this case, Vapcell’s rating of 3000mAh can still be considered accurate. It all depends on which rating you use.
I am rating this Vapcell at 30A and 2900mAh.
Unfortunately, this cell has Vapcell’s usual paper top insulating ring so juice spills could damage the ring. Be careful.
Two cells from Vapcell were donated for the purposes of testing. Thank you!
