Most articles I've come across say otherwise - best not to fully discharge Li-ion batteries ,or even go below 30% if possible. I know it's definitely bad to store fully discharged batteries.BUT I did read somewhere, can't find the article (a long time ago) that Li-Ion and Li-Po still benefit from being fully discharge from time to time. So I also run them down - maybe once a quarter or half year just for the heck of it
Yes, that's true (I didn't say otherwise) for Li-Ion and Li-Po, it's how the chemical composition is. But then again, as with any battery enabled device, you'll also run them down (phone, laptop, powerbanks) - so it's technically "the same" as saying "fully discharging" them

I am just a sucker for cases it seems. With the Van Nuys 12 has almost everything except.... room for an extra battery module, if needed. So a few days looking and settled on the Pelican 1020 Micro with the additional block foam insert. With taking what was removed and having it as padding when closed, does a good job imo.

Nice- seems much better than slotting it back into the box that the recharging unit came on, which is too tight a squeeze for it- I am always worried that I will damage the recharger when I put it back in there.I am just a sucker for cases it seems.

No problem, just sharing my experiences with others, hope it helps some!
I know how long a cardboard sleeve lasts in the wild, so definitely needed something better than the stock box. I also wanted something that would fit it in place, no movement, and keep the chip part obviously free of anything. I think this checks all boxes and can also get run over by a car if need be.

That's what I might get as wellNoice! Decided to use my extra Pelican as well and just buy new foam inserts.
Was looking for a case that would carry "all" (DAP, DAC, C9, cables, IEMs) but nothing that suits my preference. My DAP, DAC, cables already has a case I'm satisfied using. So decided to save some $ and just use this 1060 that I have extra. Some nifty cutting of the foam inserts and I have a case that snugly fits the C9

What's the current stand on battery rolling for the C9? Last I checked was a year ago, someone had found a single model that they said sounded a little cleaner than the stock ones -- but it was always out of stock so I didn't get to try it.
Any changes in the meanwhile? Any batteries that do good things for the sound? Or was battery rolling always just a bit of a... wank idea? Don't get me wrong, I'm not a sceptic. I'd of LOVE to hear there's a 20 USD pair of batteries I can buy that makes my C9 10% better

Given that people love to *fiddle* with things in audiophile arena, I strongly suspect that you hit the nail on the head with your apt formulation that battery rolling is indeed - in all likelihood - nothing more but also nothing less than a wank idea.

@Whitigir
stated of the Orbotronic 3500mAh 18650 High Drain Rechargeable Battery 3.7V Flat Top earlier in this thread
“Best batteries with blackest back ground, best sub bass and bass body, tube like transients overall, smoother trebles, great textures. Highly recommended”

I have these as my spare pair for C9. I do not hear a sonic difference Myself, but they work in all ways as well as the stock VTC6s

Sadly there doesn't seem to be any way to get those outside of the US/CAN (to the UK). Seems like these are the only one anyone's tried really, I remember trying to buy them a year ago
DAMN YOU WONDERBATTERIES! Why don't they bring them to this stupid isle! Now I will never have whitgr's black background, and will have to make due with the BAD background my regular batteries give me.

And if you can actually tell the difference then you will NEVER be satisfied. So...stick with stock.Sadly there doesn't seem to be any way to get those outside of the US/CAN (to the UK). Seems like these are the only one anyone's tried really, I remember trying to buy them a year ago
