There's two main aspects to an electric saw. Motor Watts/hp (including allowable duty cycle) and battery tech/management. Dc or brushless commutated dc motors have bottom torque because of back emf choking the works as rpm climb. Hence the tractor verdict. Batteries, aside from thermal...

I think chainsaw engine design runs a balance between outboard motor and peak power mx bike. Endless sustained torque vs short burst at bleeding rpm. I think thermal load at the piston is the limiting factor and thus also the cooling capability. Thermal masses can absorb bursts of heating but...

I cut a bit of stuff with an older friend a few years back and I had my 260 and I think his was an 034 or 038. The cut speed in the wood was similar but my motor buzzed high while his meated into the trunk. You could hear his revs really drop as the cut intensified, Visually I'd say my chain...

Was just cruising some videos and in a very recent vid Reg is still running his battery husky climbing saw. Call that a positive vote for that particular model. On fresh batteries it had reasonable grunt, but not high revving.
