yaaaaa, i have battery-operation, i am currently running an eoma68-a20 off of a 10Ah e-bike battery, and both the LTC4155 charger/dual-supply IC and the ST3115 battery guage IC are up and recogniseable on the I2C bus.
i have yet to compile up the linux kernel modules for both these devices, but they are both available... somewhere :)
only slight issue to track down: power drops to 4V when the 5V DC is plugged in, i still have to investigate that, but it may be related to the setting of 3A input and i only have a 2A 5V charger. i can change the settings, and i can also "ping" the LTC4155 over the I2C bus... maybe :)
but.... progress, yay!
