2 batteries with the same unique identifier

[metapixl]

Describe the problem

I have two FSK 300HP batteries that have the same unique identifier so only one is loading using the latest driver version. The log files says to change it but not sure where/how to do that and there are no options in the battery internal BMS to change it that I can see.

Driver version

1.2.20240227beta

Venus OS device type

Cerbo GX

Venus OS version

3.30

BMS type

Smart BMS (LLT, JBD, Overkill Solar)

Cell count

4

Battery count

2

Connection type

Serial USB adapter to RS485

Config file

[DEFAULT]

; --------- Battery Current limits ---------
MAX_BATTERY_CHARGE_CURRENT    = 70.0
MAX_BATTERY_DISCHARGE_CURRENT = 140.0

; --------- Cell Voltages ---------
; Description: Cell min/max voltages which are used to calculate the min/max battery voltage
; Example: 16 cells * 3.45V/cell = 55.2V max charge voltage. 16 cells * 2.90V = 46.4V min discharge voltage
MIN_CELL_VOLTAGE   = 2.900
; Max voltage (can seen as absorption voltage)
MAX_CELL_VOLTAGE   = 3.500
; Float voltage (can be seen as resting voltage)
FLOAT_CELL_VOLTAGE = 3.375

Any other information that may be helpful

Previous driver version did load both batteries.

Thank you for your help!

Just change the capacity from one battery as the message say.

[metapixl]

Sorry I apologize if this is a stupid question but I'm just getting into this. I don't know what file or where the capacity gets set in. I don't see a listed option in the config.default.ini to add it into the config.ini. If it's suppose to be set somewhere else?

[mr-manuel]

You have to change the capacity on the BMS itself. With the app of the BMS or PC software.

Appreciate your help. Thanks!
