I noticed that one of my Keeppower P1835J protected 18650 battery has got the plus pole some pressed in / dented. I think it happened in my Rofis TR20 flashlight. Anyone others had such problem with that battery? I think the plus pole button top is made of too soft metal alloy. Should we complain to Keeppower about that?
So we can see even lots of premium brands also have issues, with all kinds of products. Ie. my Olight SR Mini Intimitator gets damn hot running for 10 - 15 mins at only 1200lm, a brightness BLF Q8 runs very cool without problem.
