Re: Problem increasing air time by lowering low voltage cuto
OMG!
There is so many errors in these posts, I don't know where to start! I just wanna mention a few thing. Discharging a lithium polymer battery to a low level of charge can cause chemical reactions to occur within the cells of the battery, this leads to the battery "swelling up" or "puffy".
Sealing the cells is also highly important as the polymer will react with water (and moisture in the air) take a good look at your lipos, and how its sealed etc. looking at the dji phantom battery, note how much extra attention is paid the sealing the balance lead, the last thing dji wants is a battery causing an injury and them being liable.
The "rule" is 20% left in the battery / 80% drained out of the battery. So for a 2000mah battery the 20% mark would be after draining 1600mah out. And as follows:
2200mah @ 20%= 1,760mah used, 440mah remaining*
@ 10%= 1,980mah used, 220mah remaining*
*theoretically remaining, may not be actually useable power!
If electronics confuses you, think of them (batteries) as water "tanks" that hold 2200L (or Gal, if that's your thing
) if you have 20% remaining, how many L/G's is left in the tank.
The charger is the hose that fills the tank! The DJI phantom charger (claimed) can charge at 1000, 2000, or 3000 L/G (1A,2A,3A) per hour. Using an aftermarket charger that shows how many MaH has been put back in would be the same as a display telling you how many L/G's has gone back into the tank.
Also note, Mah stand for Milli-Amperes per hour, also referred to as Amp-Hours.
1000 milliamperes = 1 ampere, this is where it gets spooky
1000 Milli-Litres = 1 litre!
. . .who said water and electronics don't mix!
