NewBeeDrone's Nitro Nectar NX69 1S Battery connector rewrites power delivery for tiny whoops—more current, lower resistance, same charger. It matters if you want harder punch-outs and steadier power without swapping your charging gear.
TL:DR
The Nitro Nectar NX69 1S Battery and its NX69 connector increase theoretical conductivity by 69.6% over BT2.0. Real flights show a ~4.8% higher peak current. The connector is backward-compatible with PH2.0 chargers and comes with a 20 AWG pigtail. Batteries ship now at the same $16.99 price point.
Takeaways
- NX69 increases theoretical conductivity by 69.6% over BT2.0.
- Real peak current improved ~4.8% in tests—feelable in punch-outs.
- Backward-compatible with PH2.0 chargers; includes PH2.0 pigtail.
- Ships with Nitro Nectar 300mAh HV cells at the same $16.99 price.
- NX69 connector + Nitro Nectar NX69 1S Battery lets cells breathe, more current, less choke.
- Practical gain: ~4.8% higher peak current. You’ll notice quicker throttle response.
- Keep your PH2.0 charger, packs include pigtails for easy swap.
Why New Connector?
BT2.0 served the community, but cells keep getting faster. NewBeeDrone designed NX69 to chase higher C-rate cells without bottlenecking them. The goal: let the cell deliver full current.
Development Bite
Design work started around BT2.0's arrival. Teams tried cylinder pins, then pin-style designs. Heat, loosening, and cost torpedoed early attempts. The winning idea came from a power-core concept adapted into a U-shaped contact. Prototyped in 2025, validated in real flights.
Performance Numbers
Engineers measured a 69.6% theoretical conductivity improvement versus BT2.0. Real-world peak current rose from 25.17A to 26.38A—about a 4.81% gain. In practice that means harder acceleration and more consistent throttle under load.
How it Delivers
The NX69 pairs a 0.85 mm² pure-copper drone-side pin with a 1.34 mm² enlarged brass battery-side contact. More surface area and better conductors equal lower internal resistance. The connector performs like an 18 AWG run while using 20 AWG wiring for weight balance.
Backward Compatibility
The NX69 accepts PH2.0 plugs and can be charged on PH2.0 chargers. NewBeeDrone made transition simple—each pack ships with a PH2.0 pigtail so you can solder and swap without replacing chargers.
Mechanical Design and Materials
The battery-side contact is U-shaped brass. It grips the drone-side pin for high-contact area and durability. The drone-side pin is pure copper with 24k gold plating to limit oxidation and keep low resistance over time.
Pigtail and Wiring
NewBeeDrone uses a 90° pigtail with 20 AWG wire. The choice balances mass and performance—lighter than 18 AWG, but with internal resistance low enough to not bottleneck the NX69 contact geometry.
Nitro Nectar Cells
The NX69 connector ships paired with Nitro Nectar 300mAh HV cells. They are top-rated in the community and tuned to benefit from the connector's higher discharge capability. New cell chemistries with higher discharge rates are in development to match the plug.
Price and Availability
Price matches the previous pack: $16.99 per 4x 300mAh battery. Sold at Unmanned Tech
Whoops and Future Builds
New BeeDrone will ship the Hummingbird V4 and the Hummingbird RS V2 with NX69 power leads from today. New builds arrive ready to use—no soldering required for stock setups.
FAQ
Is the Nitro Nectar NX69 1S Battery connector compatible with my PH2.0 charger?
Yes. The NX69 is backward-compatible with PH2.0 chargers and plugs. Packs include a PH2.0 pigtail so you can charge without a new charger.
How much real-world performance gain should I expect?
Expect a measured peak current increase from about 25.17A to 26.38A—roughly 4.8% higher. That translates to firmer punch-outs and steadier throttle under heavy load.
Do I need to change wiring on my whoop to use NX69?
No mandatory rewiring. The connector performs like an 18 AWG run, but NewBeeDrone chose a 20 AWG pigtail to balance weight and resistance. Use the supplied pigtail for best results.
Will my old PH2.0 battery work in an NX69-equipped whoop?
Yes. PH2.0 batteries plug into NX69-equipped drones and will deliver about 97–98% of BT2.0 performance, according to bench and flight comparisons.
