I spent years carting around sla batteries which were heavy and a real pain. Didn't cost much.
3 years ago I spent $400 on a LIPO4 battery, it weighs only 2kg, i can run in nearly flat and it still gives 12+ volts. It powers my equipment for a few nights without recharging. One of the best astro purchases I ever made.
