Another plus for the Hill Billy is its quiet performance. Your playing partners will not be bothered by any intrusive noise. It's quieter than say its ClubRunner or Minn-Kota competitors. Most importantly, it's proven after several tryouts over some undulating layouts, it has very good power. The key here is the dependable 12 volt battery, that is sealed, maintenance free and valve regulated.
Every unit comes with a small charger that is microprocessor controlled.
So far, after repeated overnight charges, the Hill Billy has performed every time for next day 18-hole usage. The Hill Billy is easy to transport and folds up neatly into most car trunks. There's even a quick-release mechanism on the wheels. So, all in all using and transporting the unit is most agreeable. The only improvement I would like to see is having a wider base to hold one's bag.
