I got the AC and the DC chargers with my order. At first I was scratching my head at how I was going to wire them up. I know AC circuitry pretty good but DC.....not so much. Powell sent me a link that helped greatly. I will be talking to Stephen or Lithium Pro to see if there are any precautions to take in putting the AC charger on such as is it fine to just leave the DC wiring hooked up as it is. I can't see why there would be an issue but for the price of these batt's I'm taking no chances. Them babies will be maintained and treated like gold. LOL
