That's a shame in one respect, but on the other hand does mean the BMS is relatively secure.
@solarrig You'll have to play the Ali Express messaging system roulette, and remember they work 08:30-18:30 Beijing time.
This morning I finally managed to get a code, they said it only works for 15 minutes but not sure why.
Its a terrible system, why they didn't put a reset button on the BMS I don't know,
Two pins somewhere that you short to reset the BMS to factory settings. Seems like a no-brainer to me.
I was commenting that they should have included a short to clear memory.This is the guess only? Or you know/tried these pins?
I forgot my jk bms passwordIf you forget your password to enter BMS, please contact me next to BMS.
I will give you a temporary password. Validity: 15 minutes
If you forget the authorization password to modify the parameters, please open the upper right corner of the BMS to view the BMS information,
The serial number provided to my BMS,
I will give you a temporary password. Validity: 15 minutes
The code they gave me I just used to change the password, and it worked.I tried resetting a JK B2A8S20P to standard setting and control password. BMS is locked as we don't know these two passwords. 1234 and 123456 do not work.
I received a 8 digit code from a supplier. I used that code within 10min. I tried it in the 'setting Verify PWD' and 'control Verify PWD'.
On both it responded with verify permission failure.
Am I using the wrong button/place to reset?
btw, I am using Apple iPhone with IOS.
Unbelievable that JK makes it so hard to reset.
Прочетох цялата тема но не намерих верния отговор за сдвояване към bms jk.
Верният код за сдвояване е 1 2 3 4. Дано да съм полезен на някой!
