How to test ANY battery? DIY Load Test
In this video, we'll build a powerful DIY device for discharging and testing the actual capacity of batteries! When you don't have an expensive electronic load, ingenuity and ordinary heating elements come to the rescue.
I'll show you the assembly process using step-down DC-DC converters, explore connecting a voltmeter/ammeter, and test the design under extreme conditions—heating the load to 350°C!
This DIY project is ideal for those who repair electric vehicles or assemble lithium batteries.
In the video, you'll see:
How to use heating elements as a powerful resistor.
Wiring diagram for DC-DC converters for current regulation.
A real-world discharge test of a 48V battery assembly.
