True, I was debating switching to a 2 cell Li-Ion battery to cut the wasted head down from 6W max to 1.4W max. (At 1 amp.) I'm going to run by the battery store later, we'll see what I can find. I'm trying to do this without purchasing anything besides a battery (if needed.) I have some old SLA batteries, but I'm pretty sure they're 3/4 dead, so I may have to buy either a new SLA or a Li based battery.
