GAONENG 6pcs GNB 850mAh 1S LiPo Battery 60C 120C 3.8V with PH2.0 Connector for Tinyhawk Brushless 75mm FPV Drone Emax Tinyhawk S Happymodel Mobula6 HGLRC Petrel 75Whoop Spare RC Parts

I use this on my 60mm frame drone, and I added a splitter so I can have 2 connected in parallel. This changed my flight time from 4 mins with the original batteries, to over 13 minutes. Game changer in usefulness. The previous set I had lasted about 2-3 years, so they're fairly long-lasting too.

I've had good fortune with GNB and so far these are delivering a wonderful flying experience.On the Tinyhawk III, the extra weight is noticeable, but smooths throttle control and doesn't bog down the quad since it has a decent bit of throttle reserve.Compared to the Emax 450mAh batteries, these are ~35% heavier at an avg weight of 16.75g. flight time so far has averaged an incredible 8 minutes! I wouldn't call my flying style aggressive, as I'm still a rookie pilot. With the negative impact of the 4.5g penalty, this obviously won't be the battery of choice freestyle, but the minimal battery sag and ~10% gross weight increase makes it pretty good for a practicing amateur.Btw, if you have not updated the rates to Project Mockingbird for any of the Tinyhawk whoop series, you are missing out on quite a bit of potential. Happy flying!

I guess the other reviews had better luck than I. My Hummingbird V4 gets 2:10 to 3:36 of flight time on these which is less than what I get out of the GNB 660mah. Discharge is 221 to 326mah which, again, is less than the GNB 660 and the 520. These batteries were not worth 6.95 each and I will not buy these again.Revised 5/4/2025. I replaced the ph2.0 connectors with bt2.0 and gave them a run in my 75mm 1s 23000kv 0802SE drone with 5A ESCs. 1st run 8:06 at 637 mah, then 8:13 at 612mah, then 9:19 at 645mah. I am changing all of the connectors. I upgraded 1 star as they don't work great without modifications and I still have not got 850mah out of them.Updated 5/12/2025. I changed all of the ph2.0 connectors to bt 2.0. I have a 2S 82mm quad with 14000kv 0804 motors that will fly 1S or 2S and it consumes energy violently. I made an xt30 to bt2.0 1S2P connector and ran 'em. Flight time 12:39 and 1649mah used. So, these batteries will push 800mah-ish each, but in an aftermarket special application that is not off the shelf.Edited 5/17: I am flying these batteries on a 75mm 0802se 23000kv 1S quad with 40mm hqprops and getting 9:28 flight time at 660mah. That is still not 850-ish mah and the only way I know how to truly use all of these batteries is to fly 1s2p on a really thirsty quad. I will give GNB another star even though this is a totally custom application

Always need more batteries, especially with tiny quads with shorter flight times. These work great with the tinyhawk 3 freestyle.

I went from 3 1/2 minutes to 7+ minutes of flight time with these batteries and they only weight 16g compared to my emax 450 which weight 12g. These have replaced my everyday emax 450mah batteries now which are in a drawer and I use these exclusively as the extra flight time is incredible and I barely notice the additional weight and got used to it almost immediately.Highly recommend.

Work great. Perfect on THfreestlye. Hope they make 1000mah soon but then again these might be top end weight/power/size for drones in this category

Great batteries for my mobula 6 and mobula7

For me this was the edge of the balance of weight and capacity. I used these first with an hx115 lr. I noticed the flight time at first was less than gnb650 then after a charge or 2 I was getting almost a minute longer. On a smaller quad I made these perform almost indistinguishably to the 650 battery. Maybe a few more seconds. I conclude the batteries are good but they teeter on being too heavy for the voltage they provide on a really small build
