I'm shooting with a Canon RP which I love but battery life is very poor compared to the 7D I was using before. This means I need to have a few extra batteries in my bag but Canon batteries are expensive. You get what you pay for though and the cheap aftermarket batteries I've bought don't have the capacity and they don't live long. Can anyone recommend an aftermarket brand that matches the quality of the Canon batteries? They obviously wouldn't be the cheapest batteries out there but they're bound to be less money than the Canons.
Thanks

There aren't a lot of aftermarket "clones" of the LP-E17 battery the RP uses. Several I found claim to be 1040mAh and if that's true would make them the same as the Canon OEM battery.
B&H Photo has a "Vidpro" brand that claims to be 1400mAh, or about 35% higher capacity than the OEM battery. It's only $5 cheaper than the Canon OEM battery, but if the capacity is accurate should give you more shots per charge. Might be worth a try.
I have used aftermarket batteries in various Canon cameras over the years and they worked fine.
However, today I don't. But it's not because there's any problem with them now. I only have one camera that uses the small LP-E17 and it's a "casual" camera I use in a fairly specialized way, that doesn't require high capacity so I simply got a second Canon LP-E17 to carry with it.
My other "daily use" cameras are DSLRs that are less power hungry and use the larger LP-E6/E6N batteries. I have all of those fitted with battery grips that hold two batteries and use various camera setting tricks to get maximum number of shots with them: That's upwards of 2500 shots, typically. I also carry two extra batteries for each camera, in case they're needed. Often not, but sometimes I need to do a battery swap during a long day's shoot.
All my LP-E6/E6N are Canon OEM batteries.... twenty of them (three primary "user" cameras and two backups). The reason they are OEMs is because for a long time there were compatibility issues with 3rd party LP-E6. They worked, but couldn't be charged in the Canon chargers and didn't communicate fully with the cameras. The problem was that the modern OEM batteries have computer chips and firmware, which apparently took years for third party manufacturers to replicate. A few years ago one 3rd party battery manufacturer... Watson... figured it out and started producing an LP-E6 that was fully compatible. Today it's different and most 3rd party LP-E6 batteries are fully compatible, so I guess most have figured it out. If I were looking for LP-E6/E6N today, I wouldn't hesitate to buy 3rd party. (I'd just watch out for any LP-E6 that come with their own charger... check if the instructions say not to use in Canon chargers. Those are signs the batteries are the old design that's not fully compatible. I'd be afraid I might accidentally pop one into my Canon chargers and fry something!)
Something you might consider... Vello makes a BG-C18 battery grip for the RP that doubles battery capacity. It's relatively inexpensive at under $60, so don't expect it to be as high quality as Canon's own grips. Canon doesn't offer a grip for the camera and the RP is not really designed to work with one. As a result, for the Vello grip's shutter release button to work requires a somewhat awkward external cable plugged into the grip and the camera. Reportedly that gets in the way of using the image playback button. The shutter release button is the only camera control that's replicated on the grip. (Canon OEM grips for cameras designed to use them also replicate a full set of AF controls... basically most of the camera functions you reach with your right forefinger and thumb are also found of the vertical grip. This
is not the case with the Vello grip on the RP.)
Also, it's necessary to remove the grip to replace memory cards. But if you can get past these "issues", it might be a solution. It will double the power available to the camera and let you shoot twice as many shots before you need to change batteries. Of course, it will add a bit of weight to, but personally I think the vertical grip is worth it and the extra mass can help a camera better balance with larger, heavier lenses.
There's also a more expensive "Jupio" brand grip being offered for the RP. At about $120, it appears to be similar to the Vello, except that the Jupio grip comes with a wireless remote. I have little info about this grip. Just happened to find it in a search at B&H. (I know a little more about Vello, who make a number of grips for other Canon DSLRs and mirrorless. Even so, I don't have RP or this particular grip. Others are pretty similar to and have much the same controls as Canon OEM grips, when those are offered... for example, the Vello grip for 5D Mark IV. Still others for various Canon that aren't designed to use a grip... like the RP... have limited connectivity, as noted above. For example, the Vello grip for T7i, 77D.)
You also might try some other things to reduce the camera's drain on the battery:
- Set the camera to go into sleep mode in the shortest possible time. Today's cameras wake up so fast at the touch of a button that this isn't a problem when shooting (it was a problem in early digital that took several seconds to wake up... I missed a lot of shots and had avoid using sleep mode on those).
- Set the camera so that the last image taken isn't automatically replayed on the rear LCD screen. That is a heavy drain on the battery, too. Plus, it can be distracting and cause you to miss shots. I just call up an occasional shot when I want to check something. It may be possible and more convenient to map image playback to a different or additional button. (I do this on my cameras so I can replay images easily using either thumb, which is helpful with some models.)
- The RP doesn't have a built in flash, but if it did I'd get an accessory flash with its own power supply and never use the one built into the camera. Built in flashes are a major power drain. Accessory flashes are better in almost every way, anyway. They're a lot more powerful, recycle much faster and are farther from the lens axis to make for a bit less redeye and ugly shadow problems, and most have more direct controls rather than having to dive into the camera's menu to set them up... all this in addition to having their own batteries so the camera's aren't drained. Of course, since the RP doesn't have built in flash, this doesn't help you.
- If you aren't using Wifi or GPS, be sure to turn them off. They draw a lot of power, too.
- On some Canon mirrorless "continuous focus" is another battery drain. This is not the same as "Servo AF", which provides tracking of moving subjects. I don't know if it's the same on the RP, but on some cameras "continuous focus" can run even when the camera is stowed in a camera bag and may keep the camera from going into power saving sleep mode.
- It may be necessary or prudent to always switch off the camera when it's stowed or simply being carried, but not used. If it's instead in sleep mode, bumping any button can awaken the camera and needlessly drain the battery.
