Ok thanks, I just wanted to confirm b/c the older version 10 regardless hows Balance ON all the time if you toggle it on, whether it is balancing or not. This is good to know i thought i might have a faulty JK unit

I have noticed something that is not right about this BMS version 11. I have Balance set to On just like version 10. In version 10 it shows Balance On at the top just like it does with Charge and Discharge which are also on. In this new version it shows Balance Off, no matter how many times i...

Yea, it's working fine now, just have to make sure they are both near the same voltage before turning both on the same bus. Seems to be working so far. Just would like to know more about those features and how they are used. Wish JK would respond or put out new manuals frankly. The new BMS is...

Yea i've seen some of his videos but even he isn't sure on some of the features b/c he doesn't use them. The new v11 has some SOC % that version 10 doesn't have and a sleep mode and always on display I'm hoing to get more info on. The SOC % doesn't make sense b/c it won't let you set it lower...

Thanks thats an older one, i have a couple different version of that. I'm looking for a new updated one which has some of the newer parameters which show up in HW/SW v11.xx that that 10.x didn't have. I can't figure out how to get an updated manual and some of the videos doesn't really explain...

Thanks, I did a little test today and it went well. Any chance you know where I can find the latest manual which has information on the version 11 hardware and software settings. JK simply does not respond to email sadly.

Thanks thats what i wanted to confirm, i wasn't sure if there is some hidden setting or some CAN connection required between the two. I did notice if both are not fully charged to the same level the other battery will discharge quickly to charge the other in a quick test when i flipped the...

Hi, looking to get confirmation if running JK-B2A24S in parallel will be an issue. First JK connected to first battery pack, second JK connected to 2nd battery pack. Both battery packs are high voltage, same voltage and same aH and will be individually charged to 80% SOC. Each of the JK...

Where can I get the latest English JK-BMS manual which has the added SOC settings for HW Version 11.XW & SW v11.288 Thanks

Looking for new ESS-7.6 80V pack only, please PM thanks

Take a look at this, seems like some voodo is required to get it to stick https://diysolarforum.com/threads/trying-to-calibrate-jk-bms.32195/

Ordered from China, it's faster and cheaper to buy a new one if that is the issue. Everything else works fine. I think this is a FW/Software issue with these rather tahn faulty HW. There is an expectation these will be off by a voltage or two if i understand. Most don't bother with calibration...

All the other settings save but he calibration is the one which isn't happy. One of the many JK manuals state to turn off Charge and Discharge than set it. This makes no difference. It only allows you to set changes close to what the JK reports which is silly if its off when compared to...

Yes of course.

Is there a trick to getting the JK BMS to accept the voltage you put in for calibration. Keeps saying failed when putting in the actual measured voltage with calibrated DMM which is about 1.1v off from the BMS itself. Not sure if there is some magic to get this to work but I read another user...
