When you buy a BMS from LTT its still labeled as a JBD BMS so I'm pretty sure. I used to buy them from there because you'd always get the newer versions, on Aliexpress it's pretty random.

Just got the 20s JBD BMS Up and running. Why is resistance uniformity not showing anything ? And where can I check IR of the cells ?
And what does this lock , unlock thing om the Main screen ?
Thanks

I'm pretty sure it can't check IR of the pack or individual cells.
The battery score improves or worsens based on the condition of the battery, try cycling it a few times.

What about that lock /unlock thing on the dashboard ?

It disables the C- discharge port, good when you are transporting the battery.

Oh... So when im only using this BMS for charge, this has no use for me ?eee291 said:

Pretty much, I've only used it once myself.

Just tested the function. You are right.... Thanks again.eee291 said:

That is a very cool project. I dont understand why nobody responded to your reply. Did you ever get this project up and running ??
A little question for those using recent v.3.1.1013 of the xiaoxiang app.
I find this new version very important, as it provides access to all the functions, including those which required the UART box (kinda impractical once the BMS is stashed away).
But... I do not find anymore choice between "charge balance" and "static balance". More importantly, when looking at the screen with single cell voltages during charge, I cannot see the flashing "B" attesting that a specific cell is being balanced. (To be precise, only cell 1 sometimes shows "B" for a brief moment but only when changing into the cell screen.)
It seems that everything is working correctly, cells remain balanced, and the pre-charge unbalalanceis smaller than post-charge. Still, I'd like to be sure that everything is ok. Am I missing something?

OK thanks

So the data comm protocols for these BMS are the same as that used for DaveGA?
Or just talking about using it as a jumpoff point for a BMS-specific display project?

Yeah I know Davega, i´m in the esk8 world also. But the davega only works with vesc protokol right ??

Marking this thread to read - thanks for putting it together, all who were involved.
Agreed that a BLE based BMS is FTW bigtime.
This opens the door to low cost, BLE enabled, modules which can be networked. All that must be agreed upon is the interface.... and that can come long after hardware is in the wild.
With a networked system of independent modules (that play nice together, and do not try to lock each-other out of the market) you can have a battery that requests a current reduction to a controller and then a primary contactor that waits to open until loads are low. . . all of these things working together let you use smaller, lighter, lower cost parts which do not have to survive "worst case" where 60V is blowing open at 50A.

Hello.
I wanted to calibrate my smartbms (antbms), it shows me 57.7v while in reality I have 57.9v.
I cannot change "Total Voltage Reference Value" which is set to 3000N
is there a tip?
similarly I don't understand too much to limit the charge to 4.1V, I can't lower the voltage of my charger.
I tried to set totalvoltage Highprotect to 65.6v, once this voltage reaches, the charger turns off and on all the time.
my pack is a 6P16S 15Ah (67.2V at 4.2V).
Thanks for your help

I cannot modify them.
my smartbms is this one

the charger is this
https://fr.aliexpress.com/item/32778132570.html?spm=a2g0s.9042311.0.0.27426c370gPl5H
but it does not drop below 67.1 V
