I've been working as a mechanic for over a decade, and I can confidently say that a battery maintainer is one of the most essential tools for working on modern cars. Today, I'm going to show you how to DIY your very own high-demand battery maintainer using an HP Server PSU, capable of supplying up to 14 volts and 80 amps.
After watching countless videos and reading through various forums, I decided to take the plunge and create my own version. So, here's my take on the HP Power Supply 14-volt hack.
A big thanks to everyone whose efforts and ideas made this project possible!
