Greenworks 40V Lithium Ion Battery Charger 29482 - Fast Charging for Greenworks 40V Tools - Perfect for Lawn Mowers, String Trimmers & Outdoor Power Equipment

I stripped the guts out of this and put a 40v to 12v converter in it so I could use it as a power source for trolling motors, boat starting motors, boat lights, etc. Sometimes it's easier to put a 5 lb power source in the boat than two 50 lb. lead acid batteries. Works great too. A Greenworks 2 amp hour battery ran my 36 lb Motorguide trolling motor for more than 2 hours under load. The only drawback is that you have to take out 4 torx screws to change the 30 amp fuse inside the housing but so far that hasn't been a problem.Good reliable product andreasonably priced !NoneI have a city lot-60x120, with a house, garage, driveway, sidewalk, front porch, back deck, landscaping etc, which does not leave much to mow but this battery only gives enough power to mow 2/3 of the lawn before it must be recharged. So basically it’s a two day project to mow the lawn
