yesterday I made a little test on P2V "charger" ...
I'm using the double quotes because is just a plain and simple power supply that DJI call "Charger" :roll:
Anyway, I tried to power my hyperion 1420 charger and worked perfectly
there wasn't any variation in the voltage coming our from the DJI power supply that instead usually happen in the normal lipo charger proving my thought that is just power supply.
The only thing that DJI power supply have is the led that change to red when the amperage sucked from it is more than some mA then the led turn to red ... when there is no power draw then is green
Now I'm pretty sure that with a powerful enough power supply that can supply 4A for each phantom battery
you can charge how much phantom batteries you want in parallel :mrgreen:
Maybe is a good idea to put a 5A diode in series of each battery to avoid that the most charged battery get sucked by the less charged ones ... but not sure about that because a diode usually lower voltage by 0.7V so could lower the voltage of the battery being charged.
Any suggestion well appreciated :roll:
