Looks like 100% is defined to be 4230 mV, whereas your maxes out 50 mV less. Probably just normal variation in battery voltage and meter accuracy.
fennectech:
can i change the definition and recompile it?
fennectech:
im also going to charge with the boot loader is there a way i can ajust that too? when its fully charged ill report

Of course. This is an open source project, you can build the source yourself if you want.
