when did star battle r finish with 2nd battle pass?

Star Battle R’s 2nd season pass was announced in June 2023, with the DLC planned to arrive later that year in autumn to winter. The source I found does not give a single exact finish date for the whole pass, but it indicates the rollout was expected to wrap up in late 2023.

What the source says

• The 2nd season pass was revealed on June 11, 2023.

• It was described as adding three new characters later that year between autumn and winter.

• A separate store listing confirms the Season Pass 2 product existed by June 13, 2023.

Practical takeaway

If you mean when the 2nd battle pass content finished releasing , the best supported answer is late 2023 based on the “autumn and winter” timing. If you mean the exact end date of the pass on sale or the last DLC drop , I don’t have a precise date from the available result.
