Hey @pickles, I have a question.
Why does the mode in the charger change from CC to CV when the batteries are almost completely charged? I have Nitecore D2 (thanks for the help @pickles) and I charged two Samsung 25-R.
Also, the charger itself have a little burnt smel, but it's just a little. The batteries are a little warm, but nothing abnormal. Also, no noise at all.
