Good success today! I replaced the bottom resistor in the picture above in my previous post so I can push the voltage to 63V. I pushed up to 62.5V, and left it running for 20 minutes and nothing got very hot. I did not have a 2.7k resistor so I soldered 2x1.3k resistors in series, and made a...

Woot! Emailing the Germans with google translate works great! :lol: :D Hallo Kalen, der Widerstand ist auszutauschen ( unteseite vom Sekundärnetzteil ). Gruß Christian Hello Kalen, the resistance has to be replaced (unteseite from secondary power supply). greeting Christian When I get...

Thank's for posting SpmP! I have 6 of these supplies, and want to charge 84s lipo 25ah pack to 350V! To charge a retrofitted prius to improve gas milage, of course. My supply seems to shut off at 56V when I apply less than -0.2V (gets overvoltage fault). If I am not able to bump the voltages...

Thanks for the suggestions! I will have to look up Pattern matching + signal processing. And no, I don't have simuLink Power Systems module, I was hoping to get away with excel. It definitely cannot handle terabytes of data, but I figure I'll start with a few small samples to get the battery...

Hi I am trying to analyze terabytes worth of battery cycling and need some help. Essentially I have several megawatt hours of deployed and have been running for 1-3 years and would like to analyze the battery characteristics (Ah, equivalent resistance). Any idea on where to start? I see...
