Review on DC/DC 12V To 24V Boost Converter 40A 960W - Waterproof Voltage Regulator Module For Car Power Supply (10V-16V Input) by Casey Mann

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.
