My good old LiitoKala Lii 202 is going nuts. I put in a single battery and it starts blinking on both bays for no apparent reason. I also hear some beeps, first it sounds like a bunch of tones just like electronic music, and than just a solid beep sound. It does it with every 18650 battery I tried.
Only exception is AA Eneloop 1.2V, it completely ignores it.
just wondering what’s going on. Interesting it doesnt like the new phone chargers where the cable and power supply are separate… I tried a bunch but only an old one 1-piece doesnt cause the beeping.
