We are currently fiddle with a step-up boost converter trying to use a 6s lipo to charge any 10s board at about 4A. My electronics skillz are a bit rusty and I haven’t found much about the converter online. It has three potentiometers, one at the input, one in the middle to somewhat limit the current, and one at the output to set the output voltage.
Anyone here knows how to measure and set the current limit? I did think about using a power resistor at the output to simulate a load and adjust the current accordingly? Would that work or ?
