Wow, they are much worse even than I expected! Thanks for the reveal.

Have you seen this type of counterfeit 18650 battery before? UltraFire

Fist time I saw it here Photos were posted on 5th of December 2013 Locally I keep saying to people do not buy Ultrafire 4200mAh is fake like any other Ultrafire no matter what capacity is claimed, but unfortunately no one really gets anything like internal resistance, capacity at different loads, etc so Ultrafire is a very popular brand even with warnings. However I have not ever imagined this thing as a possible cause for the UltraBad quality of this brand. [image] [image]
