JK 4S 200A BMS

[maciej]

Hello,

I'm reading this thread for the first time, but unfortunately I've already bought two JK BMSes, one couple months ago and one couple weeks ago.

Can anyone tell me if I have the good or bad version of JK BMS? Also I'd like to ask how to update firmware so I could have the SOC voltage settings, because I can't see one.

I've got version with heating port. See the screen for details. Thanks in advance!

Man, that would be a lot cleaner than this;
Overkill 130 amp bms, Heltec balancer & voltage controller

If you bought it new you should be fine. The problem was only with the units sold in the first few months. I bought mine a week after Nami emailed me to tell me that they were available because I was on the wait list.

As they say, good things come to those who wait!

Thanks a lot for the answer. Yes, I bought it new in June, 2023.
