Ok, from your output and log I see that you stopped bme and loaded bq27x00 and bq2415x drivers.

Battery design capacity (which is 0) is read from rx51_battery kernel driver, which is not loaded. But this driver is part of kernel-power v52 (prerelease), so it is not present in v51.

If status menu plugin cannot read design capacity it will try to read last full capacity.

But in HAL log is missing "battery.reporting.last_full" in /org/freedesktop/Hal/devices/computer_power_supply_battery_bq27200_0 (for bq27200 chip). This can be problem if learning cycle of bq27200 was not complete. Can you write output of this?
