Bottom Line: This Cylaid is a true 25A cell that performs well and appears to be a Sony VTC rewrap.
While this cell has the 25A continuous current rating in small print on the wrap it has a useless 40A “max pulse discharge” rating on the wrap too. It also features “40A” in a larger font which many people will use as the cell’s rating when shopping or when a vendor displays it on their web site. For these reasons I feel the large “40A” rating, or any “pulse” rating, is misleading and shouldn’t be used.
It has the distinct Sony VTC top contact structure but uses a venting disk that doesn’t match any VTC venting disk I’ve seen before. This Cylaid cell doesn’t match the performance of any VTC cell I’ve tested before either.It tests out better than the VTC4 but worse than the VTC5A. I don’t know which cell they might be rewrapping.
I am rating this Cylaid at 25A and 2200mAh.
My thanks to Cylaid for donating the two cells for testing! (https://cylaid18650.en.alibaba.com)
