Review on ⚓️ Blue Sea Systems - Battery Switch ON/Off AFD: Enhance Control and Safety for Your Marine Electrical System by Rory Kelley

I installed this switch in my RV's battery box to isolate the bus batteries during storage. I gave it one star because working with 4/0 battery cables makes them difficult to bend. It's not the switch's fault, but something to watch out for if you're looking to install one. The switch works smoothly and reliably. Some have complained that mounting bolts/screws are not supplied, but as every installation is different I can understand why. I went to a big store, bought 4 1/4 x 20 2" stainless steel bolts with locknuts for my particular setup and it worked really well. Very safe. Now I don't have to visit my bus weekly to recharge the batteries.
