No, no issues. These are relatively new Wasabis, maybe this explains it? I got them about a month before the 1.2.1 firmware update, and they are fine after the update.
I promise, I would not have said they "work fine in my 5D3" if they did not work fine in my 5D3
Didn't mean to imply anything... what I was wondering is if all/some/many of the aftermarket battery manufacturers actually make their Li-Ion cells or if they buy from a "cell" vendor and repackage in their housings. That may be why your newer Wasabi's work and my old STK & Wasabi's don't.
Anyway, in this area I've decided to go all OEM. I'm going to buy the Canon "grip" and Canon OEM LP-E6 batteries. I spent almost $3k on the Camera so why risk damaging it on a reverse engineered grip and batteries of unknown origin & quality just to save a couple hundred bucks (yes, I now many people have used these aftermarket products with great success, which is great, but no-one can convince me that the OEM version isn't better, safer, and has the added benefit of being fully supported by Canon.)
But that just me over-reacting per usual...
