I put my battery in the freezer, cools it quick

Perfect

You can’t put your weight onto a battery saw while cutting, like you can a gas saw. That’s when mine “ over heats “ ( actually it just overloads the draw on the battery forcing a shutdown to save the electronics). It’s best to have a fresh file on the chain and then almost let the weight of the saw just do it’s thing. My 80v saw’s cut times are double what my 45cc gas saw’s cut times are. But for quick limbing jobs or cutting anytime you don’t want neighbours , or anybody for that matter, knowing what you’re doing battery saws are awesome.
