I won a mod a while back, so of course, I had to buy batteries and chargers. I ended up with a TrustFire charger. I think it was the only option. Not knowing anything about it, I bought it. What a mistake. It's only about two months old and one channel is already bad. The LED is green and stays green no matter what. I can put a dead battery in it and it won't charge as it thinks its already charged. Junk!
