Slinger Tennis Ball Machine Review battery issues

huge battery problems with Slinger ball machine bags. Get ready to pay $80 a year for a new battery that won't be in stock.

someone did a video with battery alternative, "Slinger Bag Battery Replacement - Cheaper Alternative" , seems like robot vacuums use the same battery voltages
