BETAFPV4pcs 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

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...

I bought 2 packs of 4, and along with the 2 batteries that came with the Whoop, I have only used one pack. They actually have a tad more power than the 550's that came with the quad. I have had some pretty gnarley crashes and they have some dents and bends but still work great.

These batteries work great on my Cetus pro. The only thing is they last 2-3 minutes in manual mode while also in fast mode. Definitely recommend buying at least 2 packs, however if you want to save a couple of bucks buy the 450 mAh lava batteries because there is no difference in flight time.

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 batteries! Much better than stock (although they don't get you more flight time than the stock 450s in my Cetus X [unless you're just hovering and then it's like 7-8 minutes]). What give you is a bit more pop, but that was on stock settings. If you reprogram the quad to 350mA on the motors it's an absolute rocket on these packs! Pair these up with one of the multi-chargers and it's a killer set because you can cycle them out faster than you can fly them. I really like the BT2.0 connectors. Coming from much bigger helis, airplanes, boats, and trucks, these are the best tiny connectors I've used besides XT30s.

I bought it for cetus x, it is little bit big, but it is ok to use

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.

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.
