1 Been into flashlights since around 2002
2 Love flashlights because they turn night into day
3 My practical uses are power outages ..camping and emergency car repairs
4 Would love to have a Tn42vn
5 I'll go half way 2700
I was wondering if I'm storing my 18650s at 3.7 volts for long term storage at what point do I need to charge them again? 3.65? 3.6?? 3.2? Also I'd it best to give them a few minutes top up just to the 3.7v or do I need to fully charge them and drain them down to 3.7v?
