Yes, in that case you are right if you look at it carefully. But JK also has systems that work completely as BMS if you want to compare it to Battium. Information at https://www.jkbms.com/good video, but it is not an BMS, this is a balancer.
It's a big difference and important to know, especially for newbies who think, an BMS is optional when using Li-Ion.
It is not, an BMS is mandatory. But an balancer is optional
