Yamaha 48 v won’t move
 

My 2013 48v Yamaha jumps a little when taking off and then goes slow and stops . Was getting a burning smell and
found all batteries had no water. Replaced all batteries . Did not realize I was boiling water out from staying on charge. Charger must not be cutting off when fully charged. My question is could have I damaged the controller from the water level being low? Do y’all think the burning smell was the controller getting to hot? Just replaced it before all this happened with the batteries . Thanks for any advice.

Well what’s your battery voltage while it tries to move? The batteries are currently brand new or these are the ones that boiled out?

Thanks for getting back . All batteries are new . Is there a way to check the controller ? Thanks
