I have a Yamaha G19 48V.
All batteries are full, 2-3 years old and cables are secure. It takes a partial charge (probably the reason I'm getting Incomplete Charge), but has very little power up hill and in fact died last night heading in garage, after only be out for about 20 minutes. I have only owned it for about 5 months, so I'm not that familiar with repairs and previous work. Any direction would be helpful. Thanks in advance for any one's assistance.
