Review on ⚡ Cllena Golf Cart DC-DC Voltage Reducer Converter - 36V/48V to 12V Buck Transformer Regulator Power Supply 30A 360W by Peter Zouhair

For the price this is a great product. It works great according to the specifications. I personally had a problem with electrical noise on a golf cart. I bought it to power a 48v audio amplifier for a 12v golf cart. Unfortunately, the electric brake made quite a bit of noise, which was transmitted via 12V. I've also tried moving the converter away from other equipment on the golf cart. I even moved it 6ft away from the golf cart while troubleshooting and kept getting noises when I hit the brakes. As part of troubleshooting, I connected the amp to a standard converter and didn't have this problem at all. In short, it works great with accessories, but if used for audio I would steer clear.
