Great battery for cordless Ryobi lawn mower
Dan S (Austin texas) 8/28/2013 7:59 AM
I bought 42 of these cells and built a battery pack for my Ryobi 48 Volt cordless lawnmower ( 6 24 volt packs each containing 7 cells). Works great. I can mow my lawn twice before I have to recharge the battery pack. Also the battery pack only weighs 9 pounds. The lead acid battery that came with the weighed over 25 pounds and I could barely mow the lawn once before I had to recharge it.
