This is a 2600mAh cell with a type number matching a Samsung cell, but the top do not match the similar names Samsung cell I have tested.

Wellp, more or less nice cell for the price I think. Discharges up to 10A but looks like far from its sweet spot at such rate. Its consistency could improve. The anode shape looks to be from Heter, as far as I know. I wonder where could we get datasheets from this and other chinese OEM cells.

Deleting a just published post causes the forum thread answer notification to fail. Thus, if you need to change your just published post, edit it. Thanks.

Please avoid fully quoting lenghty posts, namely with nested quotes. Trim quotes down to the essential. Helps with neatness and legibility. Thanks.

- Yeah, but is it ultra high CRI? Innocent

Looks closer to a Samsung 26H so maybe they should rename it!
