Sure, there is an extra gram or so in the larger batteries but I don't think that is where the problem lies.. Could it be the main motor? And if so, how do I tell? Anyone else got a take on this? Otherwise I keep it running smoothly, well lubed and perfect trim.
When mine did that it was because the main motor was bad. Could have been because of getting lube inside the motor and fouling the brushes.
