The batteries can't be reordered individually; you always have to bring all the plastic from another charger with you. But the battery is great; a colleague wanted to buy one from me right away. They're displayed in the Sony camera even without a "system error." I've never had it myself, but it was apparently always an issue with "non-Sony batteries."

Good purchase.
like the base station and the non oem batteries.
However they will not have then same run time as an oem battery.
If they lasted like an oem battery I would have given this a 5 star review.
I have them as backups and they have come in handy several times.
For the money it’s a good buy and I use them.
Overall it is a great buy. Does the job.

I've used K&F brand gear before, I always thought it was good enough for non-professional work and this battery/charger kit fits right in with that sentiment. It takes about 75-90 mins to charge to full, the batteries don't get hot while charging, and I estimate they have about 85% life of an OEM Sony battery at less than half the cost. All in all, it's a fantastic deal and I'm glad I found this kit. I'll update this review if I find any longevity or heat issues down the line.

As a photographer, having extra batteries are a must! However for Sony users, it’s the game of “oh I want more batteries but dang the OEM batteries are expensive!” And sometimes when you buy “non Sony” batteries, the camera can reject the battery itself, and I believe even void your warranty on the camera, HOWEVER, THESE WORK GREAT AND NO CODES!

One of the battery in the pack was dead within 45 days. The other battery depleted very quick. However When I reported this to K&F customer service promptly reached out to me offering to replace the unit at their cost without asking any questions. This shows K&F is trying their best to address customer concerns. My request is to ensure QC on their products to keep their brand reputation.

This is a great buy. Two batteries and a charger for my kit at the price of a single Sony battery. I couldn't be more pleased.

Just bought a used A7RV and only came with the original battery. Purchased this as a second set, as I usually need at least 3 when I'm off shooting. Batteries charged up perfectly and the charger turns green when the reach a full charge. So far, life seems as good as my original Sony. Good purchase!

They work really good in my camera for being 3rd party. I will 100% be buying another set for just incase reasons.
Edit: So I definitely ordered another set and here's why.
No 3rd party battery warning, it gives me the battery percentage number all the way until the battery dies. I've tested it on all 4 of my K&F concept batteries in my Sony A7iv.
The best part is on a full charge in "basic" 4k mode you get 2 hours of continuous filming with the Sony battery ( $85 or so each) but these K&F batteries will get you 1 hr and 52 minutes each and you get 2 of these battery and a charger for $50. 10/10 I recommend!
