Good thing I did not post seeking approval. I am posting simply to show an alternative to expensive batteries and chargers for us lift users not needing a huge investment to move small loads around the shop. As far as battery life is concerned I talked to the experts at batteries plus and explained the use. My lift draws around 25 amps which is well below what three 4 D. Agm batteries can put out without overheating. These batteries are good for over 1000. Charging cycles. I have been using this for a while now and disagree about backyard engineering being history. Some of us have made a nice living out of such engineering. You should see what my tractor can do.
