I just bought this a few days ago to play inside the house. The package included 2X 300 mah battery rated at 3.8V so I called that HV.

I didn't have a BT 2.0 connection on my "regular" chargers so I used the one provided in the kit. I am only getting 3 minutes of flight time and the pack is pretty drained.

I also bought some Tattu HV 300 mah packs. Those fared a little better and I get around 3 1/2 minutes. The charger said the pack took back 245 to 250 mah. That meant the packs are pretty drained also. 

I normally don't fly my batteries that low with my larger machines.

The ad from BetaFPV claimed 4 minutes flight time. 

So is there some issue with this machine?

Ok, I think that translate to about 4.3 amp current draw. That's sounds about right. I think the battery pack is just too small.

I ordered the wrong adapter to use my larger 1 cell battery packs so I am waiting for the correct ones. At least I can charge the packs on my "regular" chargers now so see more about what is going on.

It is a pretty cool little quad though. I can cruise all over the house with it.

that seems about right to me, i get 2-2:30 on my 1s Mob 6 and 3-4min on my 75mm with 550mah folded cells. I think BetaFPV's flight times are based on just hovering in a perfect enviroment. I've never managed to hit the advertised flight times.

Thanks for the confirmation. That makes me feel a lot better. I thought there maybe something wrong with the Meteor65. I have a Happy Model Mobula8 that I use a 2S 450 mah HV pack. I can get consistent 5 minute flights with a decent amount of juice left over. So I was spoiled.

I also fly a T Motor Feather 120 on 1 cell 660 mah HV. That I can get a 5 minute flight with close to 50 percent juice left on the pack. I don't fly that too much in the house because I am paranoid about the props hitting things.

You never get advertised flight times. It's all marketing BS just like the EV mileage claims that most car manufacturers just seem to pluck out of thin air to try and get all the gullible people to part with their hard earned cash.

Amen..............

My new less than a week old Mob6 ECO HDzero 2024 as supplied struggles to get over 1min 30s with brand new cells. I had hoped that for my fast cruise small gap flying and with the supposedly better ECO board/camera it would give longer flight times than the 2023 version. Not sufficiently so to notice or applaud.

I will EITHER be doing what I did to the 2023 version with Whoop Lite, extract all gear (can be done without cutting frame or any wiring break) and insert into a 75 frame and run 530mAh flats instead of the stupidly poor (all of them!) pencil 300's/380's that simply cannot cope with HD video demands.

OR I might cut the battery holder off and glue on an Eachine E010 one, of which I have ooodles (TM) and try the 65 frame with a 530 hung under it! (Might mask too much of the prop ducts though)

Will the 0702 motors stand that weight, the 0802's hardly notice it?

IMO there is NO POINT AT ALL in having a HD quad with great video but such a short flight time, its a bad design choice. My several years old Mob6 analogues (one of each kV) are still the best flying longest flight time 65's I have, or would be if the £15 Eachine E017 with £18 Eachine TX01 camera AIO and 200mAh rectangular cell didn't beat them by MINUTES!!

Yeah just like those C ratings on battery packs.

Once my BT 2.0 adapter shows up I am going to hang a larger capacity battery pack on the Meteor65. One of the reason I don't fly EDF because of the short flight time. I need about 5 minutes to satisfy me.

A (custom) Meteor75 on 1S gives me about 2-3 mins depending on throttle control. I always land at 3.5V with recovery to storage, but sometimes go to 3.3V, but mostly I land by 3.5V. I actually see it as a limitation of 1S. I don't have any 1S quads at the minute, but do still have a bunch of 1S packs from when i did, mostly BetaFPV 1S 300mAh and a bunch of never used Dogcom 1S 450mAh in the BT2.0 flavour. 2S is just totally superior IMO for all flying. It doesn't sag as badly as 1S and is good for most flying that I do.

Yeah I think that's the limitation of 1S also. I just was hoping the Meteor65 can do better since it is so small. I guess this is the larger Pro version so must be heavier. I have not weigh it. I also see there are some parts I can use to lighten it but not sure if it is worth the trouble.

I think hanging a large pack maybe a good work around.

Generally the smaller the props, the less thrust is possible and the efficiency is reduced. Which equals less flight time.

FTR, the BetaFPV Lipos that came with it are pretty useless. Don't use them for comparison. They sag like crazy, even with BT2.0 or GNB27 connectors. The Tattu Lipos are generally the best, but expensive. Alternatively Dogcom if you can get are good too. I only really use Dogcom for 1S now, but I don't have anything 1S. Last one I had I gave to my nephew to learn on, but he'll be going up to a 2S AIO at some point. The other possibility are these from CNHL. I fly CNHL Lipos pretty much for all sizes currently and have loads of them (due to sales). Never had any of these 1S 500mAh packs, but the ones I have in the other sizes have all been great.

I also fly Tattu 3S Lipos and some GNB 2S packs I bought a couple of years back.

I will continue to look into different batteries. Problem is that a lot of vendors will not ship to Hawaii so my choices are limited. I just had two more Tattu 2S 450 mah packs died on me. Two cells with different voltage so the pack died when the lowest voltage cell dropped too low.

If one cell dies and you are fairly daring, you can split a Lipo. So a 2S could be come a 1S. Or a 4S could be split to a 3S or 2S or 3x 1S. Just have a fire extinguisher and bucket of water on hand and do it outside away from anything that will burn. Ideally have battery voltage quite low, so less energy if it goes bang. It's not for everyone, but it is possible if you are willing to walk on the slightly more dangerous side of things.

Yeah I have done enough of the larger packs a long while ago. For 450 mah 2S packs I just plug that into a resistor and let it drain. Then recycle.

Tattu?  I'm not surprised!     YMMV, but them and their previous incarnation Gens-Ace have in my group been generically poor to abysmal.

HOWEVER, a pack that has been taken down too far for a charger to re-charge (safety lockout) can usually be brought back. Whether its worth it is down to time available, replacement availability, funds, etc, etc, don't judge!  

An an example, I have a Turnigy 1600mAh 3S that was trapped in the top of a large Oak for over a month in the weather still connected to the planes electronics. When finally recovered it had under a volt per cell.

I brought it back and its still usable years on.  This is how.

I took the charger and pack to somewhere away from anything that might be affected if it combusted, in my case an old tatty cast metal garden table positioned in the middle of my garden lawn.

I set the charger to NIMH. Depending on the charger, it might not work when set to auto number of cells, so I specify cell count.

I start charge at 1C AND STAND WATCHING IT. then as it gets to 3-3.2 volts per cell stop NIMH and immediately switch to LiPo at a charge rate of no more than 1C. I monitor it from time to time, inc case temp and as it approaches charged voltage stop charge manually.  I then run a dedicated Balancer on it  (I use ISDT BattGo)  It'll likely end around 3.80-4.00 volts on each cell. 5-10mV balanced.

It's then put to storage charge and placed away from fire risk to person/property, in my case a sealed metal case in garden. Charged normally before use under observation.  After a couple of cycles with increased care its IMO safe enough to join the normal process used.

This is what I have used successfully. Its not a recommendation, its what I have done. YOUR CHOICE, YOUR RISK.

I have also split packs where the cell is definitely dead, not just under voltage.  Last was an expensive new unused 6S 5000mAh. It wasn't an end cell, so I now have a 4S and a 1S. The 1S 5000mAh is actually very useful for bench testing and building whoops, not having to worry about the short time available from its normal cell size!  The 4S powers my drill!!

I'm getting 2-2:30 on mine using GNB 380Mah batteries! maybe i'm not flying hard enough
