When NewBeeDrone announced their new NX69 battery connector for 1S whoops, my first thought was: Do we really need another connector? After all, the FPV community is already flooded with options – PH2.0, BT2.0, A30, and even EMAX’s EM2.0. Each one promised better performance and less voltage sag.
So why did NewBeeDrone decide to introduce their own solution? I decided to test the NX69 myself and see whether it truly offers an advantage—or if it’s just another connector to add to the pile.

Where to Buy
At the time of publishing, the NX69 bundle is on sale for $17 on NBD’s site (includes 4 batteries plus a power cable for your whoop):
- NewBeeDrone: https://oscarliang.com/product-bj1p
- AliExpress: https://s.click.aliexpress.com/e/_oEDobJJ
Each box comes with 4 batteries and an NX69 battery lead, so you can swap out the existing one on your whoop.
What Is the NX69 Connector?
The NX69 is NewBeeDrone’s latest connector for 1S whoop batteries, designed as a upgrade for the aging PH2.0. It looks quite similar to PH2.0 and is even semi-compatible, but the key improvement is increased metal contact, which reduces resistance and improves power delivery.
NewBeeDrone pairs the NX69 connector with their new “laminated flat pack” LiHV batteries, which I’ll be testing alongside the connector. Fortunately, these batteries will still work with existing PH2.0 connectors on your whoop and chargers.
Specifications
For comparison, here are the size and weight differences:
- NBD Nitro Nectar 1S 300mAh battery
- Weight: 8.42g
- Dimensions: 10.4 × 6.3 × 63mm
- NX69 Power Cable length: 4cm
- BetaFPV LAVA 1S 300mAh battery
- Weight: 8.34g
- Dimensions: 10.5 × 6.5 × 64mm
The NBD Nitro Nectar 1S 300mAh is less than 0.1g heavier, but once you add the NX69 connector, the total setup is about 0.14g heavier. Might not sound a lot but this could be a consideration for the hardcore builders/racers.
Worth noting:
- NewBeeDrone uses 20AWG wires in their power cable, while BetaFPV uses 22AWG.
- In my experience, the difference between 20AWG and 22AWG in 65mm tiny whoops is negligible (more impactful in 75mm setups). I typically prefer 22AWG since it’s slightly lighter.
- However, in battery performance testing (where current draw is much higher), the thicker 20AWG could reduce resistance and make a noticeable difference.
Compatibility
One of the most important questions: Will NX69 batteries work with existing gear?
- ✅ NX69 battery → NX69 whoop/charger → Works fine.
- ✅ NX69 battery → PH2.0 whoop/charger → Works fine.
- ❌ PH2.0 battery → NX69 whoop/charger → Doesn’t fit (holes are too small).
And yes, you can charge NX69 batteries using chargers that have PH2.0 connectors.
My Testing
For this review, I used the SkyRC BD350 Battery Analyzer, which logs data and plots discharge graphs. Since the BD350 only supports a minimum of 2S, I had to connect two 1S cells in series, that’s why voltage is between 8.7V to 6V.
- The NX69 connector was tested with the new Nitro Nectar 1S 300mAh batteries.
- The BT2.0 and A30 connectors were tested with BetaFPV LAVA 1S 300mAh packs.
- I also repeated the PH2.0 test with the NX69 Nitro Nectar cells.
Each battery was discharged at a constant 12A load, stopping once the voltage dropped below 3.0V per cell. This load is a reasonable representation of the extreme demands placed on 1S or 2S micro quads, even though tiny whoops typically draw much less in real flight.
The key performance metric to look at here is voltage sag. A connector with lower resistance will show less sag, which indicates better performance.
Results
Before jumping to conclusions, it’s worth pointing out that this wasn’t a perfectly fair test. That’s because the new Nitro Nectar 300mAh cells actually turned out to have considerably higher capacity than the BetaFPV LAVA cells I used for BT2.0 and A30 testing:
- NewBeeDrone Nitro Nectar NX69 1S 300mAh → measured 345mAh
- BetaFPV LAVA 1S 300mAh → measured 316mAh
Perhaps NBD should have printed the correct number on their label, but to achieve nearly 10% extra capacity at almost the same weight is genuinely impressive.
It’s also possible that the NBD cells just have higher discharge rate than BetaFPV’s. Since they use different connectors, I couldn’t compare the cells directly against each other. Still, even with the same C rating, a higher capacity cell will tend to sag less and last longer under the same load. That likely explains why the NX69 + Nitro Nectar combo showed both lower voltage sag and lasted longer in the test.
Another factor is wire gauge:
- NBD uses 20AWG wires → a tiny bit heavier, but slightly lower resistance.
- BetaFPV uses 22AWG wires → lighter, but slightly higher resistance.
In real-world flying (especially on 65mm whoops), the performance difference may be minimal or even imperceptible, since current draw is usually modest. But in high-load tests like this, the 20AWG advantage becomes more noticeable, which again favors the NX69 setup.
Overall I think the NX69 connector’s performance is on par with BT2.0 and A30, maybe even a touch better. However, the difference is so small it’s unlikely to be noticeable in flight.
What surprised me most was that even when using the older PH2.0 connector on the whoop, the new Nitro Nectar NX69 batteries still performed exceptionally well. In fact, they rivaled BT2.0 and A30 in terms of resistance and voltage sag.
Why Another Connector?
If you’ve been in FPV for a while, this probably feels familiar. BetaFPV created BT2.0, then GNB released A30, and EMAX introduced EM2.0 — mainly to avoid licensing fees and to keep pilots locked into their own whoop + battery ecosystem. Now, NewBeeDrone is following a similar path with NX69.
Do we need another connector? Probably not. But is NX69 bad? Absolutely not. From NBD’s perspective, it makes sense:
- They already make some of the best 1S batteries and whoops on the market.
- By introducing their own connector, they ensure plug-and-play compatibility on all their ready-to-fly whoops.
- Beginners won’t need to solder and upgrade the power lead on their whoop.
Final Thoughts: Who Is the NX69 Connector For?
New Pilots Buying NewBeeDrone Whoops
For beginners, NX69 is great news. I’m glad NewBeeDrone finally modernized their connector, so customers get better performance without replacing the power cable. If you’re buying a new whoop from NBD, NX69 is a no-brainer.

Existing Pilots Already Using BT2.0 or A30
There’s no immediate need to switch.
Yes, NX69 paired with NBD’s Nitro Nectar batteries showed superior performance in my testing, but the gains are small and probably don’t justify converting an entire fleet and battery collection.
Existing Pilots Still Using PH2.0
This is where NX69 makes the most sense. If you’re still using PH2.0 on your whoop, NX69 battery packs will give you an immediate performance boost, breathing new life into your old tiny whoops. If you still have a bunch of PH2.0 batteries, keep the PH2.0 power cable on your whoop, this way it works with both PH2.0 and NX69 batteries. You’ll still benefit from the NX69 battery’s improved design when used with PH2.0. Once all your old PH2.0 packs are retired, you can then switch the whoop over to a dedicated NX69 connector to take full advantage.
That said, you might also want to consider BT2.0 or A30 because:
- They’re already widely adopted in the industry, there are more batteries to choose from.
- The next whoop you are gonna buy is likely to come with BT2.0 or A30 instead of NX69.
- It’s likely that NewBeeDrone will remain the only brand that supports NX69, for the same reason why they never adopted BT2.0.
75mm & 85mm Whoops
NX65 connector is lighter and has even lower resistance than BT2.0 and A30, however the advantage isn’t very noticeable for 65mm whoops due to the small current. It would, however, have a bigger impact on higher current requirements in 75mm and 85mm whoops.
In short: NX69 is excellent if you’re staying in the NewBeeDrone ecosystem. But outside of that, BT2.0 and A30 remain safer bets for long-term compatibility, at least for the time being.

These are some hard decisions for Air65 fleets. If it is really best 300mAh battery by that percentage. Replacing cable is not something that could not be fixed – if there is need.
But if they released their own 550mAh for 75 and 85+ which is currently hitting the 22AWG and BT2.0 ceiling, it could really hit the sweet spot to consider migrating.
Or if ppl start doing funny things with already heavy 04 systems. When we take Meteor 75 pro 04 with stock 37g and lava 550mAh 14g. Upgrading to 2*300mAh in parallel for adding like 3 grams…
Could be interesting experiment.
That’s why I hate 1s drones. Never had two of them with the same connector…
