Battery FW upgrade via P090D to DC7909 Cable?


Could you please confirm whether the BMS firmware of a B300 battery can be upgraded using the P090D to DC7909 Cable (let’s say, via an AC180)?

Many thanks.

Hi @gbk

as far as i know you only can update the firmware of B300 when the B300 actually can communicate with the Unit (Like shows current SoC in the Powerstation Display etc.)

When your using the B300 just in Powerbank mode, you cant update it.



That’s what I suspected. Thank you for confirming.
