GAONENG6pcs GNB LiPo Battery 1S 550mAh 3.7V 90C 180C with Mini A30 Connector for 75mm FPV Drone Emax Tinyhawk S NanoHawk Quadcopter Helicopter Drone FPV

Very powerful battery, great for my tiny hawk 2 freestyle. Might change your quad bandwidth tho, if receiver is set to full power.

I use these batteries for my 1s babytooth drone and flywoo dc16 drone. I get around 3-4 minutes of flight on the babytooth and 4-5 minutes on my DC16. These are my go to 1s batteries. I have 18 of these batteries and two of them had the battery lead disconnect internally after about 40cycles.

I went back and forth on battery connectors, for whoops.ph2.0 is the default but its the worst of the options. bt2.0 is too proprietary and not a big enough step up. I tried gnb27 and they are also inferior (they started to get loose after only a few weeks).xt30 is a bit bulky but as you can see in the photos, its not overly large, you get the least sag from this connector and its very snug. you can expand xt30 with a knife (pins) if they get loose, but you rarely have to.so, I'm back on xt30. tried them, returned and tried others but I'm back for good with xt30 on the whoop. remove the ph2.0 from the whoop and add your own xt30. this is stock wiring on mobula7, so I didnt add wires, I just replaced ph2.0.the batteries are a slightly snug but VERY good fit for mobula7 1s.10/10 for these. I get about 4 minutes of indoor fpv flying.(the transporter and boxer are recent purchases and I give thumbs up to them both, too)

I use these in my Tinyhawk II for a good balance of capacity and weight

Got enough of these now that I usually run out of time before battery. No problems after a few months and the batteries seem uniformly build.

These are the best I have tried! Really low resistance and the lowest voltage sag I’ve seen yet.
