    L & Z DC Motor Speed Controller 40A

    I needed a variable speed to control a MinnKota 5-speed trolling motor for my kayak fishing. I found this to be a perfect speed controller . I can adjust to 2 mph that a MinnKota can’t do. So at this speed I was able to save more on the battery since its variable controller. I would like to give a 5 star it , but the label FWD and REV is wrong. I switch to REV to go forward 😆 and the 4 terminal connection is small for 10 gauge wire. It can improved but 20 amp is good enough for me and I’m going to install a minni fan to get those mos / transistor s cool off

    Very versatile!

    I've used it with several motors and power supplies and it worked great with all of them.

    Works well but could be made better

    Worked good on first use but wish it was more water proof and gets alittle hot. No problems yet
