First 0x50 bytes are throwable.
0x54 contains a byte with power status: 0x6=good, 0x4=bad
0x57 contains a byte with power type in bit 4:
((value &0x20) == 0) running from ac-adapter
((value &0x20) != 0) running from battery
The original document claimed that this byte contained a byte with power type: 0x10=ac-adapter, 0x30=battery, whereas a PowerShot G2 just toggles one bit.
