The performance and price of battery powered stuff like that just isn't there yet. All the cordless models are more expensive than economy brand gas equivalents and don't deliver nearly as much performance. It's like how electric cars were in the 90s. Corded stuff is a pain the butt for all non-stationary work and the price advantage isn't hit or miss depending on the tool you're looking for (small corded chainsaws are slightly cheaper than their gas equivalents but the inverse it true for lawmowers)
