OVONIC 1S LiPo Battery 450mAh 100C HV 3.8V with BT2.0 Connector for FPV Tiny Whoop (4pcs)

I bought these z-fold batteries to replace the bad ones (another brand) I just bought... So far they work well... It seems this new batch of z-fold batteries have improved their low battery voltage sag... Normally these batteries go dead if you run them down to 3.3 volts, but these new ones go down to 2.9V... Normally Z-fold new batteries should be landed after it reaches 3.5 volts, but these new ones go down to 3.4V and bounce back to 3.7V after a short rest... This gives them more flight time... 30 seconds or more...

Could be better. At least compared to other 1s that over tried. Lavas are a little better. The plastic piece is a little bigger than comparable 1s batteries also. They fly but they are like 10 seconds shorter than others

pretty good, really like this brand, pretty much get all their batteries and chargers now, reliable and consistent

These batteries lasted about two weeks on a Mobula7 build with 25000 KV motors. For what that's worth. In my opinion, a better option would be the Beta FPV Blue or Lava / Tattu / GNB.

Finally got a round to flying these. I didn't realize they had a BT 2.0 connector. I had modify my old school Mobula 6 . I thought these performed very in my tiny whoop, even though these are a little bigger than what is recommended for that quad. Do these have voltage sag, yes, I have never seen a 1s battery that doesn't have voltage sag, but the batteries recover very well

Battery life lasts a good while. Doesn’t have a whole lot of weight to it but does have enough to be noticeable. Quality and functionality are definitely there for what it was needed for.

I got these for some of my 1s drones and I'm super happy that I grabbed them up. I've used Ovonic batteries in my race cars, my crawlers, my bashers and I've always had good luck with them in the past. When I saw these little 1S batteries I grabbed them fast. I'm glad I did ,these are just as high quality as all the other batteries that Ovonis has.

After flying and charging these, I like them. Great set of 1s batteries for your tiny whoop. Glad to see Ovonic release some 1s battery with the new BT2.0 connector. My only gripe with these is the sticker on the end. The sticker will get caught when putting it in my air75 whoop battery tray, whereas, another competitor battery, the sticker is tapered over the end, so it cannot get caught. So the sticker on the my ovonics are already starting to peel up/off.
