XIEGU X6100 Battery Management System (BMS)

I found this info on the Radioddity Website discussing battery charging.

This X6100 charging method is what I had found. Charge with rig OFF, charge with LED flashing until off, then charge for about an additional hour.

When turn on rig just after LED stops flashing the displayed battery voltage was around 7.9V. If let charge for the additional hour then when turn on rig the battery voltage displayed was 8.2V.

During normal charging with rig OFF I found using ext supply the current draw was around 750ma. After LED off and additional charge the current dropped to less than 250ma.

This agrees with the explanation given.

3. When should the charger be turned off?
The Charger should be used with the radio powered off. The Battery Management System (BMS) will start with a constant current charge that is indicated by a flashing Green LED. When the current demand from the battery tapers down to a steady low current set point, the charge state shifts to Constant Voltage for the 'finishing charge'. During this charging state, the Green LED will glow constantly. It is during this charging state that the 2 cells should be balanced-charged to their maximum of 4.2 VDC. The LED (in theory) should turn off when this state is completed, but there may be a conflict between the actual indicator of the completed charge and the LED Staying on to remind that the charger is still connected. I would recommend charging overnight, then toggling the charger back off in the System Setting1 Menu.
