iFlight 5pcs Fullsend 300mah HV 40C 1S Lipo Battery with JST-PH 2.0 Connector for 60-80mm Tiny Whoop Drone

I've been running these batteries in my Iflight alpha 65mm Christmas edition mini woop. I fly really hard around trees and they don't quit when all other brands started sagging after 5th use. These are on over 100 uses. I get 3.5 minutes of solid flight each on 22,000 kv 0802 motors. No more pushing the throttle to 100% after 1 minute into flight as with other brands while land now flashes at you for your last minutes. When theses say low battery there actually low from your long flight. Fits all standard 300 mah recommended frames for all 65mm woops. Dont let the 40c rating fool you, these have more power then my 60 c rated 1 cell. Iflight makes solid FPV stuff.

I love 5h2 battery itself as far as power and longevity. However 2 of the 5 I purchased after only a weak had broken a wire from it connector. The connectors are super tight, and when pulling them off, 2 of them popped through the plastic housing led 6o breaking two of the wire. But the quality of the cells themselves are great. Id buy the ones with the wire leads

Good—lasts a while. Pleased with purchase

As another reviewer has mentioned the connections are much tighter on these batteries.

Worked as advertised, great batteries

Good battery but connection to tight

The first few flights were fine but got worse and worse by the 5th flight ....they won't charge to 4.35 only 4.1 and soon as u arm and lift off they drop to 3.8 and the whoop just hovers on the ground ...not downing the company as a whole but maybe I got a bad set or something

good for price
