It's not pumping out 600W, that's how it's lighter.


My 36V brushcutter/strimmer puts out 1kW, but that is a 36V tool.


So it draws 28 amps? Must get toasty.


The batteries do get noticeably hot. Too hot for me to touch.
That is also true for a Dyson vacuum cleaner in continuous heavy use.

An AA cell can source over 10A into a dead short.
A D cell can probably manage nearer 100A. It will get hot!

It is probably one reason why their batteries don't last...
