BETAFPV 8pcs 300mAh 1S Lipo Battery 30C 4.35V with JST-PH 2.0 Powerwhoop Connector for Tiny Whoop Blade Inductrix 1S Brushless Whoop Drone

They work, but the batteries started sagging after the third or fourth charge. I never abuse them and always bring them in at 3.2v hovering on my Mobula7 (works out to around 3.7v static). They've never been below 3v while flying. I vastly prefer the Happymodel batteries that came with my Mobula7- MUCH more punchy out of the box and far less sag even after 50 recharge cycles.Amended- BetaFPV contacted me promptly and offered me a coupon code for their batteries as compensation for the packs that don't fly well. I have amended my review to reflect their excellent and fast customer service. Very stand up move by them.2nd Amendment (BEAR ARMS! Teehee)- the new packs I received fly great, much better than the first pack I got. The customer service has been excellent- literally answering me within 15 minutes to an hour each time. Good to see a company standing by their product.

ordered these to go with my starter kit 2. from the get go i notice there was a lot of what i'm hoping is white adhesive coming from the tops of ALL of the batteries. after a few charge cycles the batteries sag out quite a bit. i get maybe 2 minutes of flight time before i drop to 3.3 volts. hell even when i first start up i rarely get above 4 volts from a fresh charge. even though the charger says it's 4.29. ( never actually had them read 4.5)not happy with this really. the battery situation is kind of making me not like my entire drone set up. so I'm doing what i should have done from the start and getting a tiny hawk 2.at least i can say they were cheap.

There’s no way anyone is getting five full minutes with this battery.. I actually got longer flights with the old 260mah. I think the extra weight is making a big difference.. 2 and a half minutes so what, I was really really let down by the performance of these..Cmon BetaFPV, your products have been better than this one is.. The black plastic ends are falling off of half of them.. I guess quality control took that day off... I have a ton of their products and usually love them.. Unless I got a bad batch of them.. I am not sure if 8 individual cells will have an issue, and all eight are equally affected by it...I am going to go back and buy more 260mah cells now... GRRRRRR

These batteries are junk! After properly charging, using and storing them for the last 2 weeks 5 of them only have a flight time of 45 seconds to 1 minute. This is in a "tiny whoop" type drone. The other three will fly for 2 to 2 1/2 minutes. That is average for other batteries but for the price and the hype PLEASE look into the nitro nectars. I have some over a year old and they out perform these!!!

The good:They are relatively cheap (but not worth the trade off to me)They are the right size and not blatantly defectiveAbout what you would expect from a non HV battery as far as performanceThe bad:They drop in voltage way too quick to be useful (for anything but practice flying with sub par batteries)Use about 120 mAH before triggering low battery warningHard to keep steady powerBlack caps are not all mounted straightTLDR;questionable quality with a little overpricing for what you gethappy model brand 250mAH or 300mAH perform much better from my experiance (only comparable equivalents I have)

Im well versed in 1s batts from Crazepony to GNB to Wolfwhoop. And let me tell you these 300 mahs provide you more punch and longer flight times and only weight .6-.7 grams more per batt. Also ive noticed I keep that "fresh" battery punch you get when you first plug in a new battery longer than I do with my GNB 260's Highly recommend these batts to any whooper.

This is my second set of these batteries. The first set has held up well through many charge cycles. This second set arrived with all eight batteries between 4.04 and 4.07 volts, higher than my preferred storage charge of 3.80 to 3.85. Hopefully there will be no lasting damage.Update: I’ve run the batteries a few times and don’t see any problems from the storage charge during shipping.

These are great batteries! Are they gonna be the highest most best batteries you've ever laid eyes on, maybe not, but they'll sure gonna get you more mileage for the buck! 8 for $30?? That's awesome! These are also better than batteries with little pigtail from the battery to the connector because these fit snuggly in my Mobula 6 instead of some wire hanging off the back. It also means they're not gonna fly out mid-flight! These are way better than the stock batteries you get with your Mobula 6.
