The CNHL Long Range Series 10000mAh 21.6V 6S2P 21700 Li-ion battery combines twelve BAK 50D cells into a 216Wh extended-range pack for larger long-range FPV, cinematic aircraft, FPV wings and UAV systems using XT60. Its 6S2P architecture doubles the parallel capacity of the 5000mAh 6S1P platform while allowing electrical load to be shared across two cells in each parallel group.
At approximately 852g for the pictured production sample, the finished battery reaches approximately 254Wh/kg of pack-level energy density. This includes all twelve 21700 cells, the complete pack structure, XT60 connector, 12AWG power leads and balance wiring.
Built around the BAK 50D Power + Energy Balance platform, this battery is positioned for aircraft large enough to benefit from 216Wh of stored energy and the additional current-sharing capability of a 2P configuration. It is an extended-range Li-ion solution rather than a high-C racing or aggressive freestyle battery.

216Wh Extended-Range 6S2P Architecture
LI1000106S70XT60 uses twelve BAK 50D cells arranged as 6S2P. Six series groups establish the 21.6V nominal voltage, while two cells in each group are connected in parallel to produce 10000mAh total capacity.
The result is 216Wh of nominal stored energy, twice the energy of the corresponding 5000mAh 6S1P BAK 50D pack. For aircraft capable of carrying the additional cell mass, that creates a major increase in mission-energy reserve.
The 2P architecture also allows propulsion load to be shared across two cells in each parallel group rather than relying on one cell path.
Approx. 254Wh/kg Finished-Pack Energy Density
The pictured production battery stores 216Wh while weighing approximately 852g. That corresponds to approximately 254Wh/kg of finished-pack gravimetric energy density.
This value includes twelve cylindrical cells, pack construction, XT60 connector, 12AWG power leads and balance wiring. It therefore reflects the energy-to-weight performance of the complete battery installed in the aircraft.
For long-range aircraft, this is especially useful because total battery energy must always be evaluated against the mass required to carry it.
Why 6S2P Matters: Twice the Energy Plus Parallel Load Sharing
Moving from 6S1P to 6S2P does more than double the capacity figure. Every series group now contains two cells in parallel, allowing electrical demand to be shared across both cells.
Compared with a 5000mAh 6S1P battery using the same BAK 50D cell, this configuration provides twice the nominal capacity, twice the stored energy and greater pack-level current-sharing capability.
Finished-pack current capability still depends on the cells, internal interconnections, 12AWG wiring, XT60 connector, thermal conditions and load duration. Parallel architecture should not be treated as an unlimited current multiplier.
Powered by BAK 50D – Power + Energy Balance
The BAK 50D is the Power + Energy Balance platform in the CNHL 21700 Long Range family. It combines substantial cell-level energy with more usable power headroom than an energy-first cell designed mainly to maximize Wh/kg.
The 6S2P architecture strengthens that balance further by allowing the propulsion load to be divided across parallel cells. This makes the pack a natural choice for larger endurance aircraft whose sustained electrical demand and total mission-energy requirement exceed what a compact 1P battery can comfortably support.
Its purpose remains extended-range operation rather than repeated extreme burst loads typical of racing or aggressive freestyle systems.
10000mAh 6S Li-ion Battery for Large Long-Range FPV
This 6S2P XT60 battery is positioned for larger long-range FPV aircraft capable of efficiently carrying an 852g battery. It is not intended as the default choice for compact 7-inch builds where battery mass can quickly reduce hover and cruise efficiency.
Larger multirotors, cinematic platforms and other endurance-focused FPV systems can benefit from the 216Wh energy reserve when normal and higher-load current remain appropriate for the complete battery.
Browse additional endurance-oriented options in the CNHL Li-ion long range FPV battery collection.
A Strong Battery Direction for Cinematic UAV Platforms
Cinematic UAVs can be a particularly relevant application for a 216Wh 6S2P battery because operating time, energy reserve and payload capability can matter more than minimum battery weight alone.
The 2P architecture provides substantial stored energy while sharing electrical load across two cells in each parallel group, making it a stronger direction for larger platforms than a compact 6S1P battery.
The aircraft still needs to be designed around the pack's 852g mass, physical dimensions and actual current capability.
216Wh Battery for FPV Wings and Fixed-Wing UAVs
Large FPV wings and fixed-wing UAVs are another natural fit for this battery. Aerodynamic lift allows efficient cruise, giving these aircraft a strong opportunity to convert the 216Wh energy budget into useful distance and operating time.
Mapping, surveying, inspection and other fixed-wing UAV missions can benefit when the airframe has sufficient battery volume and payload margin to carry the pack efficiently.
Explore additional mission-oriented configurations in the CNHL Li-ion UAV battery range.
Also Suitable for Larger Efficient RC Airplanes
Although the XT60 version is positioned primarily toward long-range FPV and UAV applications, larger efficient fixed-wing RC airplanes using XT60 can also benefit from the 216Wh energy reserve.
For airplane use, battery-bay dimensions, installed mass, center of gravity, takeoff current and climb current should all be checked carefully before choosing such a high-capacity pack.
Browse the CNHL Li-ion batteries for RC airplanes and fixed-wing aircraft collection for additional options.
XT60 Connector with 12AWG Power Leads
LI1000106S70XT60 uses an XT60 main power connector with 12AWG power leads, matching the connector ecosystem used by many large long-range FPV, FPV wing and UAV systems.
The connector should not be treated as the sole determinant of battery capability. Cell platform, 6S2P architecture, internal construction, wire size, connector, airflow and actual operating conditions all influence finished-pack performance.
149 × 44 × 66mm Extended-Range Pack
The finished battery measures approximately 149 × 44 × 66mm. Its twelve-cell 6S2P construction makes it substantially larger than a 6S1P pack, so battery-bay compatibility should be checked carefully before purchase.
Allow additional clearance for the XT60 connector, 12AWG power leads, balance wiring, mounting straps and cooling airflow. For fixed-wing applications, verify center of gravity with the full 852g battery installed in its intended position.

Charging and Battery Safety
Use a charger and charge mode appropriate for Li-ion chemistry. The BAK 50D cells use a maximum charge voltage of 4.20V per cell, or 25.2V for this complete 6S battery.
Do not assume that 6S Li-ion, LiPo and LiHV batteries use identical charging profiles, warning thresholds or low-voltage cutoff settings. Confirm battery chemistry and actual operating-voltage requirements before use.
The 2P architecture provides parallel load sharing, but finished-pack capability still depends on cell limits, internal connections, 12AWG wiring, XT60 connector, cooling, ambient conditions and pack temperature.
Monitor propulsion current and battery temperature during initial aircraft setup under realistic loads before relying on the pack for extended-duration flights or missions.
