This is a very heavy duty switch, I used it on a solar install on our rv and I feel like this switch will last forever.It came with cable lugs and heat shrink tube, overall a nice package.

This battery cut off actually worked....the one that was preinstalled in our Grand Design Solitude did not - it still allowed the battery to trickle down until it was dead. This completely shuts off the battery power when shut off is engaged. Not the easiest to install, not the most difficult either. In the end, worth the time and effort to have a disconnect switch that actually does what it's supposed to do. And this is not a chintzy cheap unit, the quality and build are robust.

Very heavy duty. Works well. Mine seems to not line up right for the lockout. I drilled another small guide hole to correct that. Does anyone else find that necessary or was my unit unique?

Review of 500A Battery Disconnect SwitchI recently purchased the 500A Battery Disconnect Switch for my RV, and I must say, it has exceeded my expectations in both quality and performance. First off, the build quality is impressive; it feels robust and heavy-duty, indicating that it can handle substantial electrical loads with ease. The heft of the switch reassures me that it's not just another flimsy aftermarket part—it’s designed to last.The installation process was straightforward, but it does require some basic tools and time. The switch comes with the necessary lugs and heat shrink tubing, which was a pleasant surprise. These included components made it easier for me to secure everything properly, ensuring a safe and reliable connection. I found the instructions clear enough for someone with some DIY experience, although beginners might need to do a bit of extra research.Once installed, the switch worked flawlessly. It provides a solid cut-off from the battery, helping to prevent battery drain when my vehicle is not in use. The large size of the switch is a minor downside if you're working with limited space, but given its strong performance and durability, I consider this a worthy trade-off.The lockout plate is also a thoughtful addition, providing an extra layer of safety by preventing accidental reconnections. This feature is especially valuable in marine and RV applications where safety is paramount.In summary, the 500A Battery Disconnect Switch is an excellent investment for anyone needing a reliable battery cutoff solution for vehicles, whether it be cars, trucks, RVs, or trailers. Overall, I highly recommend this product to anyone looking for a heavy-duty battery disconnect switch that offers both quality and functionality. It’s a reliable component that gives you peace of mind, knowing that it will keep your battery safe when not in use.
