Re: Problems charging internal battery / R1CBU/R2RFE firmware


 

Regarding the charging of the internal battery of the X6100, you may want to take a look at my post ten or so days ago: /g/xiegu-x6100/message/6468 and perhaps collect some information on the battery charge process by running the 'monitor-charging' Python script while the X6100 is charging (runs on Linux and needs the USB cable connected to the 'DEV' port).
?
These are my findings from that post:
- in my case too the LED stayed solid green while the battery was charging, so I don't know if it really matters (as long as it is not completely off)
- if you look at the plot of the battery voltage and charge vs time, the logic of the internal charger of the X6100 is very simple: constant current (about 177mA) until the voltage reaches about 8.43V, then constant voltage. At constant voltage it looks like the battery is still being charged at about 35mA
- I am not a battery expert, but it looks like the batteries (there are actually two of them in the X6100 connected in series) can be overcharged above 6000mAh - in my case the firmware was showing up to 6600mAh, but looking at that plot I suspect it could have gone even higher
