Describe the bug

I am having a setup with 6 EG4 lifepower batteries. They are dipswitched 1 till 6 (verified via BMS Test program).
Only the batteries 1, 3 and 5 are successfully read by dbus-serialbattery.
Batteries 1 and 2 are 48v batteries. Batteries 3,4,5,6 are 24v batteries. Battery 3+4 and 5+6 are in series to create a 48v power bank.

I saw a user with a similair issue: #142 (comment)

How to reproduce

bash /data/etc/dbus-serialbattery/reinstall-local.sh
tail -F -n 100 /data/log/dbus-serialbattery.ttyUSB0/current | tai64nlocal

Expected behavior

Batteries 1 till 6 should be visible.

Driver version

v1.4.20240826dev

Venus OS device type

Cerbo GX

Venus OS version

v3.41

BMS type

Life/Tian Power

Cell count

16 (48v) and 8 (6v)

Battery count

6

Connection type

Serial USB adapter to RS485

Config file

;MAX_BATTERY_CHARGE_CURRENT = 300.0
;MAX_BATTERY_DISCHARGE_CURRENT = 250.0
BMS_TYPE = EG4_Lifepower
MODBUS_ADDRESSES = 0x01, 0x02, 0x03, 0x04, 0x05, 0x06
;MAX_CHARGE_CURRENT_T_FRACTION     = 0, 0.1, 0.2, 0.4, 0.8,  1,  1, 0.6,

Thanks for reading carefully all instructions and providing all the needed data.

There is a very similar issue opened at the moment, which I think could also help you: #1104

It's a different battery, but the same BMS protocol. You can quickly test, if all batteries are recognized, if you give them only odd address numbers: 1,3,5,7,9,11

Currently I did not figure out, why this is the case.

Are you maybe able to read the commands that your software sends, so that you can compare any differences between the request and answer commands from the even and odd addresses?
