JK BMS has actually has a decent manual I found in English. My JK-B1A24S-15P 150a version has been working flawlessly for over 3 months and 700 miles.
Okey, "JK BMS", thats a fancy BMS, with Bluetooth, Can -bus, active balancing..

(lots of components, more than for passive balancing, chip producer are "Texas Instruments")
btw, I was searching "smart bms" on Ebay, all are shipped from China (except one from Italy, a Jk Bms, btw).
But, I want something more ordinary, passive balancing, LEDs that tells status.
(not using a smartphone as display at the bikes handlebar)
Not a black-box bms, and not all bells and whistles.
