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

Well made and I get over 5+ minutes of cruising on the BetaFPV Meteor 75 Pro O4 quad.

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 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.

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

Great batteries

The bump in throttle response and power over the regular OEM batteries is amazing!

These are terrific thank you.

Thank you for keeping me in the air longer, I've been practicing harassing wasp nests with my Cetus!Buzz Buzz Buzz!
