I hate 2 stroke engines, mixing oil and gas, and they're often hard to start. Last year I bought a Kobalt 80 volt weed whacker from Lowes. It worked well, holds the charge for as long as I need it, and it's powerful enough to take down big weeds. We'll see how well it holds up. The problem with battery powered tools is when the batteries finally die it costs almost as much to replace the battery as it did to buy the whole tool. Reviews say Kobalt batteries last a long time. We'll see, but so far I really like it.
