Works great on a battery box

Size: 1-2-Both-OffVerified Purchase

I've added a 54ah and 23ah LifePO4 battery into a MinnKota Power Center battery box. I plan to use the 54ah battery for a trolling motor (for backcountry camping) and the 23ah for other purposes and as a backup. This switch (1-2-Both-Off) is perfect for changing the batteries without having to rewire when using them. The switch has an off position which is great for disconnecting the batteries when not in use. There is a noticeable click when changing settings so it's clear the switch has reached the right setting. I haven't used it yet to run the trolling motor but plan to do so this coming summer.

To install this on the battery box, I drilled a 2 inch hole (with a hole saw) in the corner of the battery box cover where there was a bit of empty space. It was a tight squeeze (the switch is slightly angled) but it's perfect for what I need. The side panels of the switch can be removed for connecting the wires. I used 1 foot long 6awg battery cables to connect the switch to the battery positive terminals.

The rating loses 1 star because I couldn't get the back plating cover to snap back in place no matter how hard I tried. It seems like the mounting nut and bolt are in the way. I had to tape the back plating in place.

I install this botton to shut the battery off when doing some electrical works. Sturdy. The only complain would be that the screws are a little too short. I would suggest to include a second set of screws maybe 1/4" longer for those who install it on thicker wall. Mine is installed on a 1/4" thick panel and I thinks the screws are holding with 2 threads.
