Air 3S Li-Ion Battery?

[Steelgtr]

Why the change from Li-Po? Is it a good thing? will the Li Ion batteries self discharge to storage like the old Li Poly?

thx

Nobody has a clue?

They should operate in exactly the same manner and are completely interchangeable (except for an extra feature of Sleep Transfer on the 3S battery when used in a 3S drone).

The change to Li-Ion was probably done because Li-Ion (liquid electrolyte) is generally a little safer and Li-Po (gel electrolyte) is only used when Li-Ion cannot be used for a variety of reasons including different charge/discharge, capacity, cycles, and other characteristics.

As an example, if the drone needed, say, 5 to 10 times more power (Watts, Volts x Amps) than it currently does, a 4S (four cells connected in series to increase voltage) Li-Po battery could generally discharge quicker than a 4S Li-Ion battery so the developers would use the Li-Po to meet their required discharge rates.

But again, the differences are very very small since both technologies have pretty much peaked. Next advancement is solid state batteries.

Thank you! Will the new Li ion batteries go into storage mode automatically or not needed anymore?

Page 85 of the manual does say that the batteries “will enter sleep mode during long-term storage” and to “charge the batteries to exit sleep mode.”

All of the DJI “Intelligent” batteries will do that because there is a circuit board and processor inside each battery that constantly draws power. My batteries go down to about 95% if I charge them to 100% but don’t use them until a week later.
Though it does have another feature where it will slowly discharge the battery to prevent it being at 100% for long periods but that feature starts after about 7 days of dormancy so the slow loss I see happens before that feature kicks in. That feature would also discharge the battery a little quicker than just 1% per day. So that 1%/day loss is purely due to the circuit board drawing power to function. This is why sleep mode is required for these DJI “intelligent” batteries.

All true, but the vast majority of the time lipoly is chosen is simply form-factor, for which lipoly is much more flexible (not mechanical, but rather shape).
