1 AXIOM Beta Topics
1.1 Active Battery Mount
Battery mount for NP-F970/F750/F550 batteries to power the AXIOM Beta. Includes power usage and capacity monitoring to estimate remaining charge and time remaining.
1.1.1 InfoLithium Protocol
Proprietary protocol from Sony that exchanges metadata between batteries and devices. Expected data inside the protocol includes: charge cycles, battery ID, remaining total capacity, remaining current capacity, etc.
Decrypting this protocol could give us more insight into the battery but is not essential as we can measure the discharge curve and estimate remaining capacity rather accurately that way.

2.3 Dual Micro SD Module
This module adds two micro SD card slots to the AXIOM Beta. The active slot can be switched via the card driver and both cards share a 50MByte/s interface to the Zynq. The external slots can not be used for initial booting of the camera.
