I'm not sure what you want - what your question is ?
I am NOT associated with JK or Hankzor, I only edited their manual so that it was more readable & translatable from English to other languages. I answer questions about them based on situations/conditions I've dealt with myself as I converted my fleet of batteries to JK-BMS [24S 2A 150A BT] Part Number: B2A24S15P.
In fact, I commissioned another Utility Pack (24V/105AH) and just finishing yet another 24V/280AH Pack.
I've renamed the 105 as "105-1" with No special Characters or Spaces in the name, then restarted the App as required, and voila.
Set the advanced settings to my desired profile etc, without issue. Now in this instance, I did not use the 9V Battery Start-up, I used an external power supply 24V/50A pushing 28V.
FYI, I used version 4.9.3 (build 69) APP to commission the 105 above and to manage the other packs in the bank.
- I have NOT changed Passwords though, so cannot speak to that. The default passwords are in use, the Main PW = 1234 and the administrative PW is 123456
I do not have any LCD Screens just a Power Switch which they provided.
Regarding Nami, I have tried to contact Nami myself via E-Mail which we used during the Manual Editing (Note that GMAIL a Google product is squelched in China) so I use Outlook Mail to communicate with them. I have not had any response from them either.
Pro-Tip for Startup:
1) The battery MUST be connected to a power supply or the Battery Bank.
if the New Battery is charged and too close to the Input Power that won't let it start, then you'll have to "kick it" with the 9V trick, with the 9V(+) to the B- (
you can use the B- cell post on the battery) and the 9V(-) on the LFP battery on the (-) Post.
2) If using the 9V Solution I strongly suggest buying a connector and adding lengths of wire to facilitate it. They are CHEAP usually less that $1.00
3) Once the BMS is initialized, run the App: NB Give it permission's to use GPS etc.
a) Go to Settings & select LiFePo default config, then the number of cells
b) then if you want to rename it GoTo the main App screen and click on the pencil icon. No Spaces or Special Characters !!!
c) Restart the app and the new name should appear in the list after it scans.
d) Then go back to "Settings" and set the parameters for the battery, the defaults are NOT RIGHT for LFP. while doing so you may get errors "can't write to BMS" or similar, ignore and continue to finish the settings. CHECK THEM ALL including Temps (which are screwed up). Once done with that Restart the APP again, and go verify your settings and adjust if required in case any did not take the 1st time.
Here is my Settings Screen to correct their "defaults" and resolve issues BEFORE any pop up.
<- this seems optimal with various AH packs. I have 104AH, 174AH & 280AH packs & this is the sweet spot
<- Must be 0.5C of your battery pack
<- Set MAX of the BMS model. If you have a 200A BMS then set it to that
<- LFP Max Cell Temp is 60C SET THIS !
<- Release @ 55C
<- same as above
<- same as above
<- Stop Charge at 0C Temp (32F) !
<- Can start charging at 5C Temp (41F)
<- You CAN set info here for your pack.
Hope it helps good luck.
