These things are so small it's ridiculous. Like they were made for a little toy truck or something. The two connection wires have normal thread size. You just can't do anything with them. And finally, they are dead wrong. I was going to use them for my trolling motor batteries but they are too far off the percentage remaining. I would not recommend these at all.
