Hello!
I'm building BMS 30S. Currently, I'm using two BQ76940 with passive balancing, but it's a bad solution so I decided to switch to active balancing.
I chose the ETA3000 as an external balancer, it has the EN pin to enable balancing but the BQ76940 has no output for it.
I found some IC (for example the ADBMS6815) but they are too much expensive.

Help me, please to search IC for my task.
Thanks))
