Greenworks 40v 2AH Увеличиваем емкость аккумулятора в 2 раза.

Batteries can be soldered or spot-welded. Soldering should only be done with a powerful soldering iron, using flux, and for no more than a second; the cells barely heat up. The battery is fine and works perfectly in the lawn mower. I don't recommend the 2AH 40V battery, as it also gets very hot, as the current per cell is twice as high as 4AH and 6AH batteries. Mine came with the mower; there are models without a charger and without a battery.
