Review & Re-power WORX WG775 14" Electric Lawn Mower - This baby's nuclear!!

Review and re-power of the WORX WG775 14" electric lawn mower that my brother n law was about to through out because it sucked so bad. He has had this lawn mower for a few years and it will not mow much more than 5 square foot. This will show me using a Dewalt DC9182 18V XRP Lithium-Ion 2.0 Ah Tower Battery, to run this lawn mower. I was able to mow the entire front yard with the Dewalt 18v drill battery pack going from just over 20v to 18.5v. If you look at the link below you well see the performance of the factory lead acid pack. Factory battery test: https://youtu.be/WGFQe_2LbZQ WORX WG775 Lil'Mo 14-Inch 24-Volt Cordless Lawn Mower with Removable Battery and Grass Collection Bag Cuts up to 6,000 square feet in a single charge - I guess if the pack is brand new. At just under 33 pounds this is the perfect manageable mower 3-in-1 mower mulches, rear-discharges, and bags Removable battery for charging separate from mower Easy start switch-no pull starts, Non returnable - I see why, this thing sucks. Adjustable mowing height from 1.8 to 3.3 inches; 14-inch cutting width 3-in-1 cutting for mulching, bagging, or rear discharge; push-button starting Removable battery allows for convenient charging in any location Ergonomic upswept handle reduces fatigue and improves control
