I was tempted to buy a battery powered circular saw this week to help with the disassembly of the old shed but then I discovered that my Jackery 240 battery is sufficient to run my Black and Decker Scorpion saw. This is a power saw that can be used in a number of modes. The simple wood sawing one isn’t nearly as powerful as a circular saw but for the timber on the old shed, it is more than sufficient, and certainly easier than manual sawing when you also have to hold the wood in place.
