SoloGoodTATTU 6pcs BT2.0 300mAh 1S Battery 3.8V 75C FPV Lipo Battery for FPV Tiny Whoop 1S Brushless Whoop Drone

these are great batteries! compared to gnb (a30 connector vs this one with bt2.0), this battery gives me over 3 minutes of flight time. closer to 3.30 but at least 3. with the gnb, I only get 2 minutes. that's a big difference on a 65mm quad.ONE THING TO KNOW ABOUT, THOUGH: they drop off real fast. off a cliff, fast. once they get to around 3.4 on my osd, I have to land very soon. it drops down to below 3 in a few seconds. the discharge rate at the end of cycle is FAST and you can be caught short if you dont expect that.that's the only negative. they are well priced and they fly a long time. fit is great (remove bottom sticker and it fits the m6 ECO unit perfectly)

Priced well. Perform well. Top competitor for $ worth

These are the best batteries I’ve ever used for my tiny whoops. They fit perfectly and perform amazingly.. I 100 % recommend them and I’ll be buying as many as I can afford now that it’s whoop season!! 😁

Good 👍

was a good deal for the best battery brand!

Seems like all these 1s batteries are the same these days, but tattu in my opinion is a more reliable brand as a whole compared to its competitors. I race whoops and other larger size drone. My go to is tattu products and haven’t gone back to anything else after using them. Remember never run your battery voltage under 3.2v. If you do it’s not the battery’s fault it stopped working :)Happy flying !!

Good price, good performance and good lifetime, they give about 1.30 min of hard flight and up to 3min for a more friendly flight

Tried a few other brands that just don't hold up to these. Fit and finish is way nicer and they last 20-30 seconds longer.
