The author didn't go far enough, should have ripped out the battery holder, installed a single lifepo4 or lipo, added a USB-C charging/protection board and a low quiescent current LDO to simulate 2.7V a couple of freshly charged nimh's puts out.
Author here, the best solution I think would be just ripping the temperature sensor from the battery pack and soldering it to the contact in the microphone instead, then you can just pop in regular rechargable batteries and it'll work. No need to add lipos to this.
> It is absolutely possible to do this, but the resulting battery pack won't be nearly as solid as even the third party packs that are available. With the amount of time required to fiddle with the connection paperclip and winding the temperature sensor leads around a tiny plastic tab it is probably not worth it to print your batteries.
Very common practice in music gear industry, unfortunately. I've recently bit the bullet and bought MyVolts Step Up for $20, it is literally a PD trigger worth maybe 50 cents plus a plug.
At least in the newest headset Sennheiser announced user replaceable battery, without announcing the price or if it is a standard format that you can buy everywhere or a very pricey gold-pressed latinum custom audiophile one.

Which is silly because they seem to struggle with maneuvering around the little plastic tab to have the battery detected as rechargeable.
Cool result, but just so much work for something that should be a no-brainer.
My Sennheiser RS 180 still works with normal rechargeable AAA batteries (charging on the official station).
Yet another case where the newer models are just worse.
Should see the shure ones. Shure SB900C is like $115. And at least last I looked I never saw any aftermarket ones.
At 8 mics and 6 in-ear packs you can get a lot of alkalines.
I'm glad most of my music gear isn't battery powered. I do have a painful amount of different camera chargers though...

It is ridiculous how many different battery packs canon makes.

My AA charger detects alkalines and refuses to charge them. This must be a money grab.
