That makes sense ... thanks! For clarity, is the diode you circled D310 on the schematic? The diode doesn't look too hard to remove with a hot air gun assuming the module is not too hard to access. However, would removing the diode cause DC-DC converter output disruption in some situations?

Thanks. For temporary testing, I had only Kapton tape on the bottom covering contact "6" so the pre-charge contacts on the top remain accessible. The result is that the in-rush spark appears to be less when connecting to battery without first powering on the R4850g2 *and* the output does not...

Does the contact "6" control output enable/disable?

That seems different from my experience. I see a pretty big spark that suggests a much higher in-rush current than 17A. Perhaps it's because I added the Kapton tape mod (https://endless-sphere.com/forums/viewtopic.php?f=14&t=86038&start=175#p1723367) provided by OhmSchool? I would like to...

Thank you. That's great to know. Is there any special charging procedure for parallel setup? I have been using a single unit with the edge card adapter and it seems I have to power on the unit before connecting to the battery (LiFePO4) to avoid in-rush spark. Is this typical for you? I am...

Thanks for the solution. It worked as described but I am wondering if it disables the pre-charge function?

Thanks, that's good to know. Do you run them in parallel?

Thanks for sharing the test results. Were you able to figure out the the high temp issue? It doesn't seem practical to charge with 70C temp. I don't see the such high temp using only one charger so I wonder if the parallel setup is causing the issue. How do you physically parallel the...

It's old thread but I am having same issue. Is your PSU still working after it recovered? Any idea why it started working again? I don't understand how applying 220VDC would fix the issue.
