This electric chainsaw beats out gas for limbs and small trees in my experience:

If you need more than a 16” bar, then, yeah, you’ll end up with a gas chainsaw, but the weight of battery + electric motor is less than ICE + gasoline at this size.

Also, electric is much, quieter, less smelly, less maintenance, avoids trips to the gas station, etc.
