33.x volts under full load is definitely a problem. Sometimes even a newer battery can have a good static voltage but fail under load. I suspect that this could be your problem. Clip up to your meter and check each battery to see if you can identify the culprit ... note that it could be more than 1 battery failing so check them all.
