After my left arm pumped up and I thought I was going to have a hearth attack whilst trying to start my Stihl Hedge trimmer After a winter in my shed ( the Stihl, not me) I decided I would bite the bullet and buy a battery version. The chainsaw I would get has a common battery with the hedge trimmer so would only need one for both tools. The cost for both saw and hedge trimmer and ak30 battery was £560 and I’d probably find a better deal with my local agri shop ( this was online) or at least they’d match it.
the hedge trimmer and bty was £380. But maybe your £500 one was bigger/ fancier.
