The P3 is the same size physically. This maximizes profit margin.
I also believe a 4S LiPo is rated at it's nominal voltage which is 14.8v not 15.2v.
Lower capacity (and maybe some slight improvements) reduces cell size allowing them to squeeze in 4 cells.
FAQ says P2 batteries cant be used with P3So... stupid question: Would this mean that the 3S batteries are wholly incompatible, or do you think they'd work, but just with lesser flight time?
Yup 4S is 14.8v but oddly enough, I got the voltage from the DJI website.
Lightbridge has extra power consumption.but... now 23 minutes... before (p2v) 25 minutes... I don´t know why use 4S then...
Most likely the p3 is heavier and to compensate for the weight/flight-time ratio, a whole new power system is used, one that requires more amps, discharge rating hence 4 cell instead of 3.but... now 23 minutes... before (p2v) 25 minutes... I don´t know why use 4S then...
It's about the same weight ...Most likely the p3 is heavier
that's a dollar a gram! (almost)It's about the same weight ...
Weight (including battery and propellers)
1280 g
It just has a lot going on, powering lightbridge etc and needs more juice.
Hmm, one question would be, what would the nominal voltage be on the new LiPo chemistry that has a peak charging voltage of 4.35v/cell instead of 4.2v/cell?Yea I know.
I've been using LiPos for about ten years and those numbers are atypical specifications.
Look up any 4S LiPo [nominal] voltage and get back to me.
DJI has decided to spec. it at a different charge level.
This same level would spec. the P2 Batt. an 11.4v, atypical.
