Hmmm...I am using battery powered mowers, weed whackers, edgers, etc. I hope those 40V 6 AH Lithium batteries are not a serious fire hazard. And on top of that I dropped home insurance 2 years go. I was told no risk, no gain.
You just gave me an idea. My daughter insisted on getting a battery powered mower, and charges the pair of lithium battery packs on top of her clothes dryer (metal top deck).
Now I'm thinking of creating a concrete box lined inside with fire bricks, so she'll be able to charge the batteries outside in the back yard. If they catch on fire, the fire bricks will contain it. I use fire bricks when welding with a gas torch.
Did the same, no home owners, but I get anxious come hurricane season
