TATTU 500mAh 1S Lipo Battery Pack 3.7V 95C with JST-PHR Plug for Emax Tiny Hawk/Happymodel Snapper7

Works well

I have several 65mm fpv tiny whoop drones, I have been running 3.8hv 380mah batteries in them which gave me around 4 1/2 mins of flight. These R-line 500mah batteries give me around 7 1/2 mins of flight. That is outstanding for a tiny whoop drone. They are a little heavier than the 380mah batteries thay I usually use but, my drones seem to handle the xtra weight just fine. I have bought tons of drone batteries over the years, so you can trust me when I say these are really good batteries. I just ordered more of them.

One of the lowest voltage drop under load 1s batteries I have used. Very pleased with this battery. I put these in RC DLGs and they work great for them. I left power on my glider for over a week and dropped the voltage down to 0.2v which normally means that a LiPo battery has been severely damaged but I slow charged it at 0.1 ma up to 3.6v and then charged it at 1C up to full charge and put back in 522 mAh so it didn't lose anything during that abuse. Voltage drop under load is still low even after that. 2 Flights on it after that and it is still going strong and no sign of puffing of the battery. I will of course be monitoring it for future flights as it has been abused but I am really impressed so far. I will be buying more as I need them.

Good batteries like all of tattu's r-line definitely has a great punch and runtime on my tiny whoop but after maybe 20 charges one is not lasting as long as the other

Needed a larger capacity 1S battery for a model rocketry project. Most of my electronic use a 2S battery (and what I have for 1S uses very small like 100-150 mAh batteries). This was a nice find at a great price. Able to easily power my project without worrying about it dying on me while I am out in the field.

I fully charged the lipo battery took it to the park this morning put it in my airplane and it acted like it went dead within less than a minute put a 5-year-old battery in there and flew for a couple of minutes so I think your battery is junk

Great little cell for my Tiny Hawk!
