BETAFPV 5pcs Lava 1S 260mAh Lipo Battery 3.8V 80C LiHV Battery with BT2.0 Connector Compatible for FPV Tiny Whoop Drone Quadcopter Like Air65, Meteor65, Meteor65 Pro 1S Brushless Drones

I normally use 300mAh lipos for my Air 65, so I decided to test out the new 260mAh lipos and they worked wonderfully... They are 1.3G lighter then most 300mAh lipos and I get 4 minutes flight time cruzing and 3 minutes hard flying ACRO... When I first used them I had to learn how to fly with a lighter whoop, but it only took a dozen flights to adjust... Now there are the only batteries I will use in my Air 65 tiny whoops...

On time no issues stull useing them I have only burnt one up in 6 months that's amazing

These things are top of the line. They charge up to 4.35v and with a 17g whoop, I can get 2:30-3 minutes of high throttle flying with disarmed voltage reading around 3.5v. I'd recommend these for anyone trying to make their ultralight whoop even lighter, or anyone flying 65mm.

I get about 3min flight time on a custom 65mm whoop EDIT: Just over 2 weeks and one of them is dead. No longer works and the connector looks burnt. EDIT AGAIN: They reached out about my concerns, and seemed genuinely concerned that the product had failed and sent new batteries. Glad to see a company that takes product feedback seriously.

These are fantastic little batteries. After quite a few charge cycles they are holding up well despite quite a bit of abuse. They are very sag resistant and recover quickly even with 29,000kv 0702 rcinpower motors. Would highly recommend these for 65mm whoops weighing 20g or less.

These are so legit!!! Perfect for that full send with an analogue 65mm whoop!!!

These perform great. I'm no racer, just fly around freestyle for fun. These batteries have great performance. I personally am not dialed in enough to be able to really feel the weight difference, and I don't usually drain my batteries, so I don't notice a huge flight time difference either. I just notice their great performance.

these are fun for extra light weight battery without much flight time loss but 270mah seems to degrade faster then 300mah. due to the fact that most chargers don't go below .3apms which makes it charge a little faster then the optimal 1c (.27amps) , they Do seem to be less prone to bending and damage as it doesn't stick out of the frame so maybe if you plan to freestyle and smash it a bunch these would make sense and theoretically be longer lasting if you been smashing the 300mah too often.
