HELP - I think the Hammer top has fried my batteries. I was using AW IMR 18350 3.7V 700mAh batteries. They were working fine for a bit, now when on the charger, the light is green so I assume they are charged. I then put them in the persei to use with the 1200 Hammer and the light flashes 5 times. I tried using the same batteries with cart top and the light does not even turn on.
Next, I tried using Trustfire 18350 3.7V 1200mAh. The lower part where the batteries are got real hot so I immediately stopped using it and it looks like one of the batteries exploded. (see picture below).
I then had some Ultrafire XSL 18350 3.7V 1200mAh which I tried. These batteries worked perfect for about 12 hours. Now, they say they are charged on the charger (green light) but don't power on the Hammer. The light turns on very dim for a split second and then turns off. When I press it again, it flashes 5 times.
Is it a battery issue or the Hammer top? It worked so good for quite awhile, bummer sauce.
