Review on Tnisesm 12V Battery Master Switch With Green Knob - Top Post Marine Battery Isolator For Cars, Trucks, Boats, RVs, ATVs, And Motorcycles - Cut/Shut Off Disconnect Switch For Optimized Performance by Steven Brouillard
Works in principle.
Purchased for 2001 ford E450 rv. Was looking to help reduce parasitic draw on starter battery for rv storage. Do wish the unit was a heavier build quality. Ok for occasional use. Seems to conduct current with little resistances. The screw down wheel has no locking position, so it could possible jar loose. Turning the contact wheel too tight may cause breakage’s.
- The fast delivery and the exact product as shown I. The picture.
- The switch may not be suitable for all types of vehicles, as some models may require a more specialized or customized battery isolator
