    Its not so much the weight but the cost of buying 8kg of lithium cells. For Kress, each of those battery packs is $1500 and they offer a charger for $15k. Now imagine you need to buy 2, 3, or 4 of these and regularly replace the packs as they go bad.

        Those might be too weak to effectively do their job. The Kress ones are 1500m³/h vs 900m³/h flow and 190MPH vs 130MPH wind speed. Plus those come with a 5AH battery which is only enough capacity to run my cordless grinder for about 20 minutes for example.
