Looking for some input on charging the batteries for my Vamo. I started with 2 no brand 18350's and those always charge in 5-6 hours and the charger turns the LEDs green when done. I decided I wanted to get some 18650's to reduce my downtime and I'm not sure if I am having issues with the charger or batteries. I have left these batteries on the charger as long as 12 hours and the LED never turns green. I took them off to avoid issue although I really need some input... Please help!!! Charger: TrustFire TR-001 Batteries: Samsung 18650 2600mah 3.7v Li-ion Panasonic 18650 3400mah 3.7v Li-ion. 1. How long does it take to charge these batteries? 2. Once charged should the charger light turn green? 3. After placing in Vamo what should the battery voltage read at? 4. Are these even compatible with the Vamo?
