Why doesn't this surprise me? I took the cover off, is one of these chips the one you are referring to? After watching the function disappear on the second BMS immediately after updating I am more than absolutely 100% certain there WAS heating.

There's been way too much back and fourth with my vendor who's playing the middle man with JK. It's an ongoing issue. I tried to get the JKPB2A16S-20P that lost its heating (originally V15.06) to update from V15.10 to V15.11. Bluetooth works fine but there is no PC communication? This BMS will...

Not sure the technical nsme but "weld on stud" shold sum it up.

Just a little update on this. Once the unit was apart it was pretty clear that the unit had been dropped. The power supply was bent sideways but it tested ok anyway. There were many little tests to follow and the whole process took well over a month but they finally agreed to ship a new unit...

Interesting.. I think I remember seeing a video of someone trying to charge one well below zero but I don't remember the outcome. Yup check out your datasheet. Even if low temperature IR will compensate for high C rates I don't think this will hold true at higher temperatures. IMHO temperature...

EVE LF280K's here: Have you seen the dbus-serialbattery project at Github? If you scroll down to line 255 in the config you'll see some of their control logics.

@Sleeper85 any future plans to add temperature compensated charging limitations?

Since smaller fusing for anything over 48VDC is hard to come by, I thought I'd throw this out there: Blade style ATO fusing rated 80VDC 3A-30A: https://mou.sr/4bWDPnD Fuse holders rated 80VDC 30A: https://mou.sr/3Ti0xzg

Nicely done!

That's a brilliantly simple setup. I'd strongly consider it myself if i had more capacity and my install wasn't remote. Your cells are in an unheated shipping container? How cold do ambient temps drop?

Solar panel and snap disc thermostat?

There are lots of tutorials floating around. Here is a YouTube video from Brad Cagle.

Victron Connect as well as VRM should work just fine with your Pi.

Can you link me to the firmware files? The only ones I see on his google drive are v15.10

No go but it was worth a try.. Could be but I'm not prepared to wire balance leads in at this point. I looked at this but did not see firmware other than v15.10. I've contacted the vendor but that's moving slow. I reached out to JK directly through WhatsApp which can be summed up to a...
