BETAFPV 4pcs Lava 550mAh 1S 3.8V LiHV 75C FPV LiPo Battery with BT2.0 Connector for 1-2S FPV Tiny Whoop Drone Quadcopters Like Meteor75, Meteor75 Pro, Cetus Pro 1S Brushless Drones, Cetus X 2S Quad

Great batteries! One of the best 550 1s LiHv's ive used so far. The A30 GNB 550's are a close second, but these can sometimes manage to get an extra 30secs of useable flight time safely on my Meteor75 Pro 1s O4 and M75Pro 1s Analog! I can get a full 5mins with these with the Meteor75 Pro 1s O4 and about 5:30-6min on the Meteor75 Pro 1s or my Mobula7 1s Tinywhoop's! Theyre putting out over 25Amps on the O4 version because of the extra weight and bigger motors/props than my Mob7. As good as they are, they are expensive but if they hold up over time and are durable then I will be happy with the Value for money at least. They are easy to use and slide right into the battery holders of all 3 of my Tinywhoops.. They function properly, work well, charge fast, and seem to be very durable so far after about 10 charge cycles. I will update if they start to degrade quickly, but 1s Lipo's/LiHv's just seem to never be the most durable batteries when it comes to fpv drones lol.. So im more interested to see how the durability is of these versus the GNB 550mah A30's I also bought a set of. Get the 550's and forget the 450's. Same price and almost an extra Min of flight time with barely any weight penalty!

I have 8 of these in heavy rotation and they take a beating and keep delivering punch. I've flone about 50 - 60 cycles on each of these on a modified meteor75 with 2500KV 802 motors, and I regularly get 7 minutes + flight times, 5 minutes if I am pushing it. I often head back to land only to realize I have another full minute or so of flying left. They are also durable, the label that wraps entirely around the battery along the wide side makes inserting and removing them from your frame quite easy, and unlike others I've tried, the label holds up to abuse. I've only managed to tear one that I probably should have pitched anyway after it folded into my USB port during a pretty nasty crash. I broke the USB off the FC on that one, but the battery is still in rotation with no issues (after straightening it out a little). These are GRADE A++ S Tier. The second photo is the damage I caused by taking a full-speed head-on crash into concrete. The battery was disconnected and the frame was broken, but it's still performing great. That is the only one that I damaged the label on.

Great battery, I think the voltage sag is a quite a bit less noticeable compared to the Tattu version

These batteries are great, using them on a meteor75. Indoor flights, inside my home, I'm getting like 4-5 minutes a battery lightly cruising around. Outdoor flights, with a big backyard and lots of altitude drop ins, I'm getting like 3 minutes a battery. These four with the original two batteries gives me plenty of fun!! My only concern is after inserting the batteries into the battery carrying slot, the outer wrapping of a battery or two has started to peel apart and be difficult to put into the slot.

Liking these batteries quite a bit! Battery life is what you'd expect with a tinywhoop. They fit perfectly in the BetaFPV Meteor75 Pro O4. I have been charging them to 4.35v at 0.5amps before flight, and after flight, I store them at 3.8v. Price for 4 batteries is very fair for what you get, and worth picking up 8 if you can. The label doesn't snag and get caught up on the battery mount like another brand I have tried, they slide in smoothly.

I use these 550mAh lipos for my Meteor 75 pro HD... For normal flying it will get around 8 minutes flight time and around 5 minutes for hard LOS freestyle flying... These LAVA lipos are perfect for this size whoop, they even work well for my AIR 75 flying outdoors... For indoors 550mAh is a little heavy for precise flying, use a 450mAh instead... There is not too much battery sag on punch-outs... One of the best performing 550mAh lipos on the market today, I would recommend... UPDATE one of the 4 batteries went bad after 10 flights, only 30 seconds of flight... Plus another one gives half the flight times of the other two... I change my recommendation, I would not buy these LAVA lipos again...

Hands down the BEST batteries for 75mm 1s builds or toothpicks. Heck, I've even used them on 65mm whoops with 0802 motors and they can rip! (Pro tip, 3D print in TPU a battery harness is possible for them). When new and treated right, I can easily pull 5-6 minute flights of moderately aggressive freestyle on a custom 75mm whoop running 0802 25,000kv motors and Gemfan bi-blade props. Awesome! They've seen some rough crashes too. After monitoring, still saw zero signs of puffing or swelling. Just bend em back into place and carry on. Over time after some rough treatment, they will degrade a bit, but that's to be expected. You'll get a lot of uses out of them before that point! Just don't leave them charged at 4.35v for more than ~36-72 hours ideally or cell performance might start to degrade over time. I usually try and bring my flights in around 3.4v or 3.2v if I'm pushing it.

They work great 👍 got 9min of casual flying in my room on my air75.
