Cascaded balancers (Neey)

[FusionStorage-DF]

Hi is it possible to set this op for cascaded balanceres out of the box?
min/max, voltage etc. of the hole stack

I don't understand your question. Could you describe your idea / setup / use case?

[FusionStorage-DF]

it is so you can have multible balanceres in series when you have more then 24 cells.

so 2 cells is overlapping,

It would be nice if it can show as one pack, insted of multible balancers?

Got it. You can use this project to retrieve all the measurements from two device but you have to calculate the min/max voltage over all cell voltages on your own (f.e. using a template sensor + lambda).

Ok Thanks! New in this esphome stuff, so trying to understand how it works ;)

Ping me if you need some guidance. The first step will be to talk to both balancers using a single ESP32.

Thank you Sir :) Do you know if the esp32-s3 is still limited to 3 bt devices? the spec says it should be able to have 9 connections?

At the moment there is a hard limit in ESPHome so you aren't able to create more BLE client instances: esphome/esphome#7088

In general it's a soft limit and depends on available resources.
