I have two JK B2A3-88S20P BMS for last nine months or so, and working fine both on the kitchen table, no inverter, and. in the RV all hooked up. Now, I just received a new BMS, B2A8S20P, and have connected it up, in the kitchen, no inverter or other equip, just the BMS and I receive a...

There are two BMS passwords. First to enter the BMS is a BT password. You can get that here: https://mirofromdiro.github.io/JK-firmware-code/ Once you BT login, you will be taken to the first status page. Use the left top menu to go back to the BMS ‘devices’ page, or swipe from left to right...

Just like the question, can someone please figure out a method to hard reset a JK/Helteck BMS?

So JK is difficult to get a hold of... my seller contacted them a number of times when a software update locked me out of my JKs, and we were on the road. He'd contact them about 8:00 pm CST, and they'd provide the BT temp password to log in. After that I could get into my settings password...

Shaun, I got the info on the BT password solution here at the forum from Ep1phany, great what to do, solved that issue I had of several months. So far the BMS have been working well, and fortunately they were setup correctly before the BT password thing hit while on a two month road trip.

You might have to uninstall first before attempting to install the new version. Has happened the same to me 5x.

Thanks Steve.

Still wanting to find out from a wisened user if I can use one of these new JK BMSs for a 4S setup? Those only show 8S and higher. I'd think it's be possible by telling the BNS I've only got 4S https://srikobatteries.com/?s=jk+inverter+bms&post_type=product Thank you.

Excellent! Worked and solved my issue. Thank you for making the detailed followthrough!

Yes, thank you. JK has a new BMS inverter type gadget... JKBMS 8S 16S 24V 48V 100A 150A 200A 8S-16S Family Energy Storage Lifepo4/Li-ion/LTO Inverter https://srikobatteries.com/?s=jk+inverter+bms&post_type=product Those only show 8S and higher. On my 4-8S ones I'm using, I can just not...

Can I use one of these inverter BMS for a 4S setup, 12V? Can't find one for a 4S system.

Does the JK BMS software have a place to change the BT password, by itself, which is different than the overall, once you have bluetoothed into the bms, 'Settings' password, and if so, where is that BT password change option? This is for a B2A4-8S20P If it exists, it is not on V 4.17, nor on...

I've not been able to find that BT password change area, Would you please put up a photo of that menu and location? Device list, meaning from the app page which scans/shows the several bms devices? On that initial screen, after bt scans it lists the two bms I have. The top far right initial...

Now, a few folks have talked about once they get into their BMS, they 'change' the password. I suspect they change their "settings" password. I have not found anywhere to change the BT password. Where would that be?

JK has a HQ in the US. Since they sell worldwide, you can file almost virtually where you live. No need to swim. You'd pull them right into your local town. They'd have to swim.
