the battery you have is Li on you need to enter this standard.
After connecting your battery, use the right-hand key to search for Li-on or Lipo, then enter.
Using the +/- keys, look for voltage 7.4 and enter, then look for Amperage 800Mhm, then enter using the right-hand key.
Once the data has been saved, it should appear on the screen!
Press the Enter key on the right for 2 seconds and if the standards are correct, the charger will indicate (Amps, voltage and charging time).
If not, start the process all over again!

hello Anonymous unfortunately it's complicated to explain it by email, the system is simple to adjust once the first one is done.
The best thing is the user manual which I can't send you but I advise you to look it up on the net where it's available in German and English but you can translate it into French afterwards.
best regards
