Ok so I got the nitecore i4, 4 18650 batteries at about ten this morning. Through em on around 11 got home around 4 and they lights had turned solid so I assumed they were charged. Then I used one up untill now 1am and it displayed my ohm at 9.9 then said low v. This is where the issue arose. I try all my other batteries there all saying low v. So I put them back on and the lights are blinking. So how did my batteries discharge themself. It seems like a concidence it happend and now there all low v. Did something happen to my Vamo, did the batteries discharge, do I have the meaning of the lights wrong. Please help me this has ruind my day if my Vamo is shot already I will be upset. Batteries are 2000mah efest 18650.
