Properly used, stored, etc.  what is the publish expected cycle/recharge times verses what actual users are experiencing? Also, with the stoppage of the P4 production, what is the expected availability of the P4 intelligent Battery for spare/replacement parts?

I'm sure the P4 will continue on sale for the next year and the P4 Pro is new and uses compatible batteries so there is no reason to worry for a long time yet!  I won't be surprised if the P5 also uses compatible batteries.

My last flight was 23:30 minutes on a battery that has flown 50Km, I'm not noticing a loss of capacity.  I do keep the self discharge on 2 days and normally only half charge it after a flight if I'm not flying again for a few days.

so far no one knows the lifespan of the P4 batteries as the aircraft has only been out for 11 months. there are many many batteries in inventory between the P4 and P4P aircraft. seems like an endless supply.

the life span of lipo batteries is 3000 cycles at rated Ah. i expect at least 1000 cycles or two years of normal use. this is an intelligent battery and for how much it costs it is at least expected to fail on recharge rather than airborne.

I have a  number of batteries both p4 and p4p I noticed that of the total of 14 that we have one has an error message "broken" when we fly it. It has 270 or so cycles, and last less than 20 minutes. The capacity is no longer 5380 even when fully charge on any of the p4 batteries. These batteries where purchased from Aug of 2016 to Oct of 2016. We have had other warnings on batteries but they seem to go away after we cycle them a few times.
