My main camera is a Canon 5dmkiv and I'm a big fan of backup batteries (the camera is battery hungry!) but the OEMs are extremely expensive. My current three Canon batteries are aging, I needed something new for my camera.

I have several Edelkrone motion control products that are also battery hungry and are powered by the LP-E6NH. I order third party batteries for the Edelkrone gear and that was my original intention of trying them out.

These are closer to Canon's surface than any other third party. They charge well with the included charger or Canon's. (And the included charger does a great job with the OEMs, too.)

My 5div recognized these batteries and displayed them at 100% charge and three bars of charge power (max), allows me to register them - gives the same information I get from the OEM. After checking that, I decided to actually use them to take pictures. For the first time I felt safe doing that with this camera.

I'm having a hard time doing a scientific comparison of battery life. I've used each of the K&F batteries in the camera until they were pretty depleted and they seemed to last about the same as my Canon's, maybe a little longer as those age.

So basically these are high quality alternatives to OEM products at a more attractive price point while still offering excellent performance. I would definitely order more.
