Man, I totally feel that frustration. I remember my first trip out to the coast with my R and I genuinely thought one battery would get me through a whole sunset session... boy was I wrong. Halfway through the golden hour, the screen just went black. Unfortunately, these mirrorless bodies eat power way faster than the old DSLRs ever did. I tried using some cheap off-brand batteries I found online to save a few bucks, but honestly, they were garbage. They didnt hold a charge and one actually got stuck in the chamber because it swelled up. Total nightmare. Nowadays I dont leave the house without the Canon BG-E22 Battery Grip. It adds some weight which is kinda annoying, but it lets me use two batteries at once. You really need to stick with the Canon LP-E6NH Lithium-Ion Battery too. The older versions work, but they just dont have the same juice for high-speed shooting and the camera wont even reach its max frame rate without the newer NH version. As for cards, I had a massive scare with a generic brand where the card just gave up halfway through a street shoot. I lost like 200 shots. It was devastating. I swapped everything over to the SanDisk 128GB Extreme PRO SDXC UHS-I 200MB/s and havent had a single corruption since. Its a bit pricier than the budget stuff but not having your gear fail in the middle of a rainy Seattle day is worth every penny tbh. Just dont cheap out on the power or storage, it always bites you in the end.

Just catching up on this thread! I was so terrified of ruining my R with weird off-brand power, but I found a fantastic trick! I love using the Anker 511 Charger Nano 3 30W to top off during breaks. It is such an amazing budget-friendly way to keep going without buying tons of batteries! Works perfectly and feels way safer than cheap knockoffs... honestly such a life saver!
