JBD BMS info or wiring diagram for JBD-SP15S020 V1.3

I have a few JBD-SP15S020 BMS's They came with batteries i bought,. But no instructions.
These BMS's are actually 15s BMS's But wired for 12s. From some place called RJXZS BMS.
I discovered they were 15s by opening the cover. There is spaces open for more balance leads. but not present.
And there is soldered jumpers on the back side of the header pins.
All components are present for 15s. But i want to wire this for 14s setup..
I just downloaded the app to use "Overkill Solar" was suggested from what i have been reading.
I had seen a few possible diagrams, But i'd love to see something to know for sure..
Any help is appreciated..Thanks.

Scroll down to the wiring diagrams then look for your model.

I wasn't aware of any that left leads disconnected, normally the unused get jumpered together.

I got it figured out.. Yay!
These BMS's are rebranded.. Took much time to find solution.
It's working well, i just have to tweak the settings.
I has to connect pins 14 +15 together to set it for 14s.
Case closed...

Hey, all, I'm back... Can someone look at my settings, and tell me if anything might be causing the BMS to cycle while charging..
It charges, then drops out, then it resumes charging. it does this constantly.. I can't figure out why.. suggestions..

BUMP..... help...

How many amps are you trying to charge at?
Your charge current limit might be set to low. (remember the value is in mA)

The "level 2 protection" settings seem off. Set them to
overcurrent 120A
overvoltage 60000 mv (same)
undervoltage 42000mv (4200 is totally wrong)

Otherwise I can only suggest experimenting with over/undercurrent and voltage settings to stop the cycling.
And make sure your charger isn't doing something crazy.

Could one cell be hitting the high voltage cut off?
Just a thought.

was charging at 10 amps, then 5 amps, it does it eitherway...

Ahhh, Ok, I see, I'll change that.... I wish there was a way to change ma. to Amps.. so easy to confuse me..
