Powerful 48V charger for electric vehicles, do it yourself
🛠️ Video Description:
In this video, I'll show you how to build a powerful and affordable charger for 36-48V batteries using affordable but powerful server power supplies and a step-up module from Aliexpress. You'll learn how to power up a Cisco server power supply (UCSC-PSU1-770W V04) on a desktop. This option is significantly cheaper than factory chargers, but it provides up to 15A of current, allowing you to charge the battery much faster. I'll cover case assembly, connecting a volt-ammeter, setting the output voltage and current, and I'll also conduct tests at home and using a car charging station.
