Man, I feel your pain on this. Canon prices are getting out of hand, it's honestly exhausting. I really wanted to move away from OEM for my documentary work, but my experience with third-party options has been kinda disappointing lately. Since youre heading into the middle of nowhere in Oregon, you really gotta be careful about those metadata issues.

• SWIT LB-SU90C 90Wh Li-Ion Battery: I tried these because the USB-C and D-tap ports are so convenient for rigging a monitor. Unfortunately, I had issues with the camera not recognizing the remaining runtime after the latest C70 firmware. It just shows a generic battery icon without the minutes remaining, which is super stressful when you cant just pop back to a charger.
• Core SWX NANO-C98 14.8V Battery: I picked a couple of these up last year. While the power delivery is solid, the build quality was not as good as expected for the price. One of the D-tap port covers snapped off almost immediately, and I've had it handshake poorly with the camera once or twice, causing a random shutdown. Honestly, if your budget is $600, you might be able to snag one Canon BP-A60 6200mAh Battery and maybe a smaller Canon BP-A30 3100mAh Battery. Its frustrating to pay the premium, but for a remote shoot, I wouldnt trust my kit to Wasabi or Patona. They just feel too cheap for a pro rig and the voltage drop-off is unpredictable. Let me know if you need help finding a dealer with better pricing, usually some of the smaller shops have better deals than the big sites...

> trying those newer Wasabi or Patona ones but they feel kinda cheap for a pro rig Late to the party but I've been running the Wasabi Power BP-A60 Replacement 6700mAh Battery on my C70 for a year now and honestly, I'm super happy with them. I was scared about the metadata thing too after hearing horror stories about sudden shutdowns. Last summer I did a three-day shoot in the heat and they held up just as well as my official Canons. The percentage readout on the screen stayed accurate all the way down to about 5% which was a huge relief during long takes. Quick tip: dont forget a dedicated dual charger like the Wasabi Power Dual Charger for Canon BP-A60 instead of charging through the body. It seems to keep the cells balanced way better. For 600 bucks you could buy like five of these and still have cash left over for snacks. No complaints here, they just work well for my kit.

Caught this thread today and man, I totally feel the stress of gear prep! I had a nightmare shoot once where my cheapo batteries just cut out at 20 percent and I lost the most incredible sunset shot... never again! Regarding what #2 said about the Core SWX metadata, thats 100 percent the most important thing to watch. If the camera and battery arent speaking the same language, youre gonna have a bad time in the Oregon woods. I've been using the Hawk-Woods DV-C98 98Wh Li-Ion Battery for my C70 and honestly it's been fantastic! It feels way more rugged than the Wasabi stuff and the metadata is rock solid. Love the built-in D-tap too. Another amazing choice if you want to save a bit more is the Indipro Tools Micro-Series 98Wh Battery for Canon BP-A60. I've run three of those for a year now and they still report perfectly accurate runtimes. You could probably grab three of the Indipros and stay right under that 600 buck limit. Good luck on the doc!

Quick reply while I have a sec. If you need metadata reliability, the Core SWX Nano-C98 14.8V 98Wh Battery is a decent option. It communicates well with the C70. Its basically essential to check if the unit supports the latest SMBus protocol to avoid those sudden shutdowns. Also, keep in mind that using the D-tap can occasionally cause uneven cell drain, so check the LED gauge regularly tho.
