BETAFPV8pcs BT2.0 300mAh 1S Battery 3.8V 30C/60C Lipo with 1.0mm Banana Connector for Tiny Whoop Brushless Whoop Drone Like Cetus Kit Air65 Brushless Drone

Good batteries. They hold charge well and give decent flight time for my tiny whoop. Good price and I’ve put a good amount of cycles on them with no noticeable decline in power. They seem to be pretty durable.

I bought it for cetus x. Fits well, good battery life

the 2 batteries that came with the cletus were never really enough in the first place, and especially once I started flying more regularly and they got worn out I wanted enough to be able to rotate through without having to wait around to fly. Did the job and fit perfect, as should be expected.Was debating getting the 450 mah version and modifying the celtus slightly to carry it. Longer flight time would've been nice but with the small size of the drone performance definitely would've been compromised.

I got the set of 8 of these BT2.0 300mah batteries for my Meteor65 and it flies great. Tons of power with the 20000kv motors and I get about 2;00-2:15 mins of aggressive flying per battery. If you want longer flight times but a but less power, I would say get the 19500kv version of the meteor and put that new JESC firmware with RPM filtering. I hear that adds 30% more time to you flights. I like the new BT2.0 connector, it is very easy to connect and disconnect, yet it stays snug. Also it clear has less sag and better performance than a typical PH2.0. I recommend getting the USB charger and checker when you get these batteries because it is very useful if you forget converters for your charger. Tight now these are the only battery option that comes stock with a BT2.0 but I hope this new connector gets used by other battery manufacturers so it can be successful long term. These new Beta Batteries are much better than their old 1S batteries but they er still not super high end performers. Right now they are the only and best options for your Meteor65 if you do now want to mod batteries yourself.

Works amazing! So much powah and punch! The old PH connector batteries would sag to 2.9 or 3 volt before landing. I quickly found out that if I ran these to that level they wouldn't recover to 3.7-3.8 after landing. When using these on tiny whoops (mine is a beta65s w 7x16 motors) set your low voltage warnings to 3.4V and land quickly after it hits. That way they should be right around your storage voltage of 3.7 to 3.8V a few minutes after you unplug. I can tell these will last a LOT longer with proper care and less voltage sag.

Those BT2.0 connectors make such a huge difference! I fly these in my Meteor65 and they've got plenty of punch and power.

The new ends are great. Far better than any previous connector for micro quad batteries.

These are the older model of BetaFPV's BT2.0 batteries.They were shipped from a re-seller in Spain called "Gavimosa Consultoria, Sociedad Limitada" despite ordering from the BetaFPV store.They arrived in a puffed out condition and were stored at the wrong voltage. I've received a few things from this re-seller and they've generally not been good. Proceed at your own risk.Flight times were barely a minute on a 65mm whoop. I think these are part of some old back stock that was improperly cared for and is now being sold off for cheap.Key points:Mislabelled on the box (not Li-HV!)Poor battery life -- clearly not stored well.You're lucky if you get 1 min of flight time on a 65mm whoop.Poor quality and not worth it, even if they may seem cheap -- Well, you get what you pay for and they're cheap for a reason!
