With the onset of the Mavic 3 hopefully appearing soon, it got me thinking will the Mavic 2 Pro be forgotten about now that it is discontinued, like any piece of tech it is only as good as the battery pack that powers it & we all know these 100% fail over time, I have a (water) damaged pack that I managed to fish from a lake I was filming in Liverpool, it was only in the water for seconds but in that time was enough to be wrecked by the short circuit caused, anyway on stripping the pack down I can see the cells are in good non bloated condition, even though they were not holding as much capacity as they did the year before, so on searching Aliexpress I found a supplier of X4 pouch cells identical in spec to the orig for around £61, may be a possible fix for future use of the Mavic 2 Pro long after new battery packs are no longer available, also got to add, the strip down of the pack was fairly easy, so not beyond most operator repair skills.

Though I whole heartedly agree with you.
I suspect the problem will not be the actual cells but the controlling circuit board and its chips.
You might find that if the voltage seen by the board gets really low something in the board will switch off one of the power 'chips' and that the board then requires 'specialised' equipment and software to switch that chip back on. With that chip switched off the "battery" can neither be charged via normal means nor used to power anything via the normal output terminals.

This happens with Phantom 3 batteries and I have a Mavic 2 battery that seems to have the same 'problem'.

Aside from that aspect doesn't the board also measure the 'health' of the cells, if so whatever stores that information may need to be reset.
 
I wouldn't risk it with the M2, those batteries pop off quite readily without trying other cells in them.
Best to get some spare battereis now while available, no odubt they will discontinue battery production like they did with the M1P / MPP, Spark, Air, I1.

One of the aftermarket type battery supplier MIGHT start making the M2 batts, like they did the M1P / MPP, haven't seen after market for the Spark or Air though.

Had the same thoughts of course. Just ordered 2 batts for M2P. Wether I will need them or not based on history. Flysafe and Godspeed, Droniac

Funny, no not funny, I have the same problem, and I'm sure I'm not the only one.
After 3 bloated batteries, I was searching too on the internet for replacing the cells.
I found at Ali 2 different wholesalers and I order at one shop a 4 cell-pack, ad at the other shop 4 seperate cells.
Today I got the 4 cell-pack and quickly try to replace this but.....the cells are loaded but after assembling nothing happens when you push the button or try to charging the pack.

I waiting for the 4 seperated cells but with this experience I'm scared I lose my money.
I wonder where it go's wrong?

OK, after a while searching here on the forum I see it is a matter of BM of the batterie, and is not easy to unlock the SBS-chip of the batterie.
At the moment it is already difficult to get a new batterie from DJI, do they expect if they don't deliver new batteries for the Mavic 2anymore , I buy a new DJI??? With the same results after a few year?
NO WAY DJI, then is this the last DJI ever.

when you replace the cells, you need to put another dummy pack to be "always on" otherwise the battery will brick. Or tiy can buy a chip writer and unlock it, however will cost you another 20-30 USD
