The charger for the Kobalt mower and grass trimmer from Lowes charges the batteries faster than I can use them. However, the batteries are only good for 30 minutes or so, and the equipment is hardly commercial-grade. The batteries can also be palmed with one hand, so there's room for an upgrade for commercial use.
