3 Slot D Cell Battery Holder With Two Wires (10PC)

by folks doing a quick little fun project tonight that a few of you may be interested in finally going to be making a proper charger for 18 650 lithium cells these came with a flashlight we just recently purchased the flashlight uses three cells at a time and it also came with this garbage little charger that only does two so there's the first problem it takes forever to charge and one of the cells is actually being overcharged all the time almost up to four point three volts very bad for lithium's and as we know 4.2 is the maximum you should get these two and I even want to go lower than that and that's the beauty of using a RC computerized charger you can you know program the maximum charge voltage and I think I'm going to set these to a maximum of four point one maybe even four because you know when you charge these they're sitting in the flashlight then for who knows how long before
