早前在網上找到的文件都強調新Controller Type-12 是不用電池的，內部的Cache 在斷電時會自動抄到FLASH保存。
在9月開放下載的Hardware Maintenance guide 找到這個terms
Each control module includes a cache-to-flash module for storing recently-used data.
又找到這句
When connected, the control module cache-to-flash module receives full charge
最後找到這張圖
睇來似用電容來提供由cache-to-flash 所需的電力。
