Review: Heavy duty protection for your battery bank - When you need a simple and effective, quality constructed battery disconnect. Added this to prevent charging of my LifePo Lithium batteries when the tempatures are down. The OEM setup failed to account for the new Lithium charging restrictions and placed the OEM disconnect in the incorrect location, allowing the truck 7-way and the AC inverter/DC converter to charge the battery even when the OEM disconnect was activated.
Review: Super heavy duty design - Fantastic design and heavy duty. Put on my dump truck and it works great. These are heavy duty and the handle it large so it’s easy turn.
