I purchased a 2022 Ryobi RM300E and installed the Power Queen 48v 30ah battery. Everything went well and cut neighbor's yard and mine and had 49% left. The battery was at 99% when I received it. I plugged in the stock Ryobi OP48RM Charger and the green light on the port blinks steadily and the green light on the charger is constant. However, it seems like the battery went from 49% to 29% over night. The power queen app shows no power or current. Discharge is toggled on the in the app. The temp sensor is hooked to the positive terminal. Anyone have a clue why this may be happening?
