I have an 80v Kobalt. When I got it, I needed it now and it was the only one left in town during the Christmas rush. It's not bad. The Dewalt might be better but the Kobalt did come with a quick charger that charges at twice the speed of the Dewalt.

Note that you can't charge them in temps below 32F. That will screw up Li batteries. Some, like the Kobalt, have automatic switches on the chargers that won't charge when it's that cold. You can run them in any temps but keep the charger in the house when it's below freezing.
