Review on SoloGood TATTU 5Pcs 300MAh 1S Battery 3.8V 75C FPV Lipo Battery With PH2.0 Plug Connector For FPV Tiny Whoop 1S Brushless Whoop Drone by Ryan Pal

These are high tech batteries, but like all high end batteries, like NewBeeDrone nitro nectar gold 300mAh these batteries provide great power little battery sag, but they don't last very long, 25 to 65 flights then they puff and sag like all batteries. If you are a racer, these batteries are perfect for you, they will give you enough power to win races if you are good enough. They just won't last very long. The only batteries that last a very long time over a year or more are Tiny Whoop 333mAh batteries, they don't give as much high voltage the first 25 flight, but they remain great batteries for their entire life.
