Dear team,

We have three M100, and I installed the secondery battery compartment in all of them. Normally we tun on the main battery, the second battery turns on automatically. But this changed now for some reason. Now I have to turn on both battery everytime. do you know why and how can fix that ?

Note: we have over 100 batteries and it could be updating the batteries issue or sth like that ?

Thanks,
Samer

I checked mine which has latest aircraft and battery firmware and I have to manually turn on 2nd battery. I cant see how the second battery would turn on automattically as it is only connected through the XT60 connector and not other control lines.  By the way..someoen just told me how they connect a 10000mah 6s battery to the 2nd xt60 port  for much longer flight time
