adjustable Cheap Chinese Active Balancers

And please go for a bms and not a balance only.

Hello Igor,
as you could read into the text we are talking about the jkbms series - which combines BMS and active balancer in one device.

No need to disassemble something and balancing / calculating manually

btw: I took a screencapture totday so you can see the balancer working

Hi Stefan,

I used your instructions to get my BMS up and running with the Bluetooth app...

Have you had any success communicating with the RS485 module??

I emailed Jk-BMS a couple times to try to obtain the RS485 module protocol but have not heard back from them..

Cheers Brad

at this time I did not try the RS485, but I will, in future when I have more time for this (have to set up a linux server too)
But I have some protocol documents and lots of other information about the JKBMS I collected here: https://mona-stefan.de/li-ion-akkus-18650/akkus/15-ladegerate-&amp-kapazitatstester

you may need GTranslate because it's in German, but the protocol files you'll find when you scroll down to the end of this page.

Please let us know if you have some success with the RS485

Had to do a little searching but I think i found the Docs "Polar Air Active Balance Protection Board" is what I'm looking for????
It shows how the frame data structure is sent and received....
sorry about your tractor in the water hole!!!!

Thank for the information I will give it a try... Not that good with code yet but will learn as I go...

Thanks again
