Cllena DC 8V-40V to 13.8V 25A Automatic Buck Boost Converter Step Down/Up Regulator Voltage Reducer Converter Waterproof Regulated DC Power Supply for Golf Cart Club Car LED Light

Works perfect! I was a little worried about doing it since I didnt see anyone with the set up I was trying to achieve in my RV. But basically I installed 12kw of lithium’s in my 5th wheel but its all 48v so I still had to keep the old flooded lead acid batteries for all the lights, slides, jacks, etc. I took 4 of these and wired them into my 48v lithium and then on the other end wired it right into the same wire the old 12v batteries were. Gives me 120 amps of power so all of the jacks work flawlessly and the lights are steady. Most importantly it saved me a ton of space and weight, these things are tiny and I just made a piece of wood to mount them on up and out of the way.

Super easy to wire up. I have taken it to 600W and it will work. It does get slightly warm at that amount of power but it gets the job done.

Works great to power your Headlights, tail & brake lights. Also can be used if you want to add a 12 volt stereo, Christmas lights, or power outlet.

For the price, this is a great item. It works perfectly for to specs.I personally had an issue with electrical noise on the golf cart. I purchased this to provide 12V to an audio amplifier on a 48V golf cart. Unfortunately, the electric brake caused quite a bit of noise to be transmitted though the 12V. I attempted too move the convertor away from any other devices on the golf cart...even moving it away from the golf cart 6ft when I was troubleshooting, and continued to get the noise when the brake was applied. Part of my troubleshooting, I connected the amp to the stock converter and did not have this issue at all.Long story short, it works great for accessories, but if using for audio, I would stay away from this.

I bought this the 36v to 24v 20A so I could power a 24v kid's ride on toy that should draw a maximum of 15A. No moving parts, no pinned connections to worry about how to solder, just apply voltage and it works! If you try to price anything similar from a big electronics store, it can be difficult to find and very expensive.Both I and a child rode the ride-on around for 20 min or so. Converter was not even warm. Hope it continues working as well as it has initially.Instructions were clear and concise.

Aunque no se pudo incluir en el proyecto, el equipo responde a una gran robustez y confiabilidad

I have ordered three of these 25 amp units from Amazon, between May 2022 and June 2022, that have not worked and I have returned to Amazon. I have experience with the 20 amp units that regulated the dc input to 13.8 volts and worked perfectly. Amazon must have a bad run of these 25 amp units. I just ordered a fourth unit utilizing Amazons excellent return policy. I will update my rating if the fourth units actually works. Again this is a problem with the 25 amp units.Update 6/14/2022, I just tested the fourth unit that I received and it was also bad. I have returned all four. This is the 8-40 volt, regulated to 13.8 volts, 25 amps. DC840138-25.

Seems to work great, using it to run a 24-volt air conditioner off the 12v battery.So far, it is holding up well.

excelente

To reduce from 44 to 58.4 volts to 24V

Great product, completely waterproof and very stable power with 4.5A draw. Will be ordering a dozen more shortly. Great product and quick shipping to Canada

Installed 3 weeks ago, running on a 24/7 basis, functioning as expected. Seems to be fine. Relatively inexpensive, so I will order a spare as back up. Running 12Vdc loads on an island cottage, critical component for communications, pumping water, VHF radio etc. Island’S solar system is 48Vdc, so needed a step down transformer for conversionNow running for five years, no problems. Great product.

It performed as stated. DC voltage in and a constant 13.8 volts out. nice product for my garden tractor voltage regulator.
