DC 36V/48V Step Down to 12V 20A 240W Buck Converter Regulator Power Supply Module Buck Transformer, Waterproof Voltage Reducer for Golf Cart, forklifts Car

Super easy to install. Made my lithium swap a million times easier.

First one I received didn’t work. Second one works perfectly. I double side taped it to the inside of the golf cart and ran it to a fuse box for all my 12v things. And if I ever need to upgrade to more than 20amps, the quick connectors are going to be great.

Easy install

Works wonderful

Definitely it must have when upgrading to lithium, really nice unit that mounts very well, definitely does what it’s supposed to very effectively.

We used this on a golf cart. It was maybe 4 months of weekends only that it was used. It failed leaving us stranded in the dark literally!

I've bought a few of these for multiple purposes. Originally I bought it so I could run 12v LED lights directly from my 36v e-bike battery. I have since bought a couple more for some more esoteric projects. I have used one to revive a completely dead car battery. A "smart" battery charger wouldn't even try to charge my wife's car battery after it sat for a little over a month without use. I connected one of these to a 250W (37.5v) solar panel and the 12v part to the dead car battery. After a few hours in the sun, the voltage on the battery came back up to 11-12v, which was enough to convince the battery charger that it could charge on its own. I have also used it in an experiment to run a 12v water pump directly from those same 250w solar panels. I was able to rig it up to convert the 37.5v down to 12v for the pump, which then pulled water out of my swimming pool, ran through a length of black pipe to heat up the water, and dump it back into the pool. All without any external electricity input! The pool got too warm for comfort in the summer, so I shut the project down, but knowing I can do this during the shoulder months will help us extend the swim season. And finally, I am now using one to power some 12v LED grow lights directly from a solar panel. It's like the plants live on the same cycle as ones grown directly by the actual sun, since this only kicks on when the panel generates enough power to run the lights, and automatically shuts down when the sun goes down. The plants are healthy and safe from outdoor heat, frost and high winds, and again there are no ongoing costs for electricity. Highly recommended if you need to convert voltages.

Work says it should

Works as described

Install on 48volt golf cart. Works great.

The product worked great I used it on my golf cart to hook up my rear lights and front headlight that I also purchased on Amazon.

Did the trick
