I use my Max II mostly for ice fishing. I spend a lot of time driving out on lakes in the dark. The original headlights are dim, so I want to add a small LED bar. Maybe one about 12 inches. I am wondering about the draw this light will cause on the battery. The temp many days that I fish is around zero farenheit, so the battery is already operating in harsh conditions. I got a great battery and keep it on a battery tender when at home and not in use. I don't know a lot about this stuff. Just worried a dead battery could leave me stranded.
