Re: charger or batteries
3 year old batteries could be the issue but first, standing pack voltage is 50 or so volts but what is the voltage under load. That is where it counts. The charger could be weak but since the voltage is sitting at 50 or so volts im pretty sure the charger isnt the issue. It will time out because its trying to charge batteries that arent fully taking a charge so it just runs and runs until it turns off. Lets start with what the voltage is in the pack under load. You can clip your wires from the volt meter to the main pos and the main neg and read voltage when you take off on the cart. What is the lowest voltage reading you get?
