The CNHL Long Range Series 5000mAh 21.6V 6S1P 21700 Li-ion battery combines six BAK 50D cells into a compact 108Wh pack designed around long-range FPV, FPV wings and efficient 6S aircraft. The 50D platform provides a strong balance between stored energy and usable power capability, making this one of the core long-range configurations in the CNHL 21700 family.
At approximately 432g for the pictured production sample, the finished battery achieves approximately 250Wh/kg of pack-level energy density. That figure includes the complete battery assembly, XT60 connector, 12AWG power leads and balance wiring rather than describing the cells alone.
This XT60 version is positioned primarily for efficient long-range and cinematic FPV systems where endurance matters but the aircraft still needs useful power headroom for climbing, maneuvering and changing flight conditions. It is not positioned as a direct substitute for a high-C racing or aggressive freestyle LiPo.

108Wh in a Compact 6S1P 21700 Battery
Six BAK 50D cells are connected in series to create a 21.6V nominal, 5000mAh and 108Wh 6S1P battery. Because the pack remains 1P, it achieves this 6S energy level using only six cylindrical cells rather than adding a second parallel group.
That relatively low cell count is important for long-range FPV aircraft, where battery weight directly affects hover power, cruise efficiency and total flight endurance.
For an efficient 6S aircraft, this configuration provides a strong middle ground between compact pack architecture and substantial stored energy.
Approx. 250Wh/kg Finished-Pack Energy Density
The pictured battery stores 108Wh while weighing approximately 432g. That gives a calculated finished-pack gravimetric energy density of approximately 250Wh/kg.
This is a pack-level figure rather than a bare-cell calculation. It includes the physical battery assembly, wiring, XT60 connector and balance lead that the aircraft actually carries.
For long-range aircraft, this provides a useful metric because additional endurance ultimately depends on how much usable energy is added relative to the battery mass being carried.
Powered by BAK 50D – Power + Energy Balance
The BAK 50D is the Power + Energy Balance cell platform in the CNHL 21700 Long Range family. Each cell provides 5000mAh rated capacity and 18Wh rated energy while maintaining more usable current headroom than a cell designed primarily around maximum possible energy storage.
That distinction matters in a 6S1P FPV battery. Long-range flying may spend much of the mission at efficient cruise or hover conditions, but climbing, acceleration, wind correction and recovery maneuvers can require significantly higher current.
The 50D therefore gives this pack a more versatile endurance-oriented power profile than an energy-first design selected solely for maximum mAh.
BAK 50D Discharge Capability in a 6S1P Pack
The underlying BAK 50D specification includes a maximum discharge condition of up to 5C without temperature cutoff. An 8C condition is specified only with the required 70°C temperature cutoff.
For the 5000mAh 50D cell, those values correspond numerically to 25A and 40A cell-level conditions. Because this battery uses a 1P architecture, current is not divided between multiple parallel cells.
The 40A figure should not be interpreted as an unrestricted continuous rating for this finished battery. Pack capability also depends on temperature, internal interconnections, 12AWG wiring, XT60 connector, airflow, load duration and ambient conditions.
For aircraft setup, actual measured propulsion current and battery temperature provide more meaningful guidance than treating a single maximum cell-condition number as a universal pack rating.
6S 21700 Battery for Long-Range FPV
This 5000mAh 6S1P XT60 configuration is one of the core products in the CNHL long-range FPV platform. It combines a compact six-cell architecture with 108Wh of stored energy and the more power-balanced character of the 50D cell.
That makes it particularly relevant to efficient long-range multirotors where battery mass, hover current and usable energy must be carefully balanced. The goal is not maximum burst performance, but enough usable power capability to support a real aircraft while maintaining strong endurance potential.

Built for Efficient Cinematic FPV and Cruising
Cinematic and cruising-focused FPV aircraft can be a strong match for Li-ion because their power profile is often very different from racing or aggressive freestyle. Rather than repeatedly demanding maximum acceleration, these aircraft can spend more time operating near an efficient cruise point.
The 108Wh energy capacity of this pack can therefore be especially useful when the propulsion system is optimized for endurance and the normal electrical load remains within the battery's limits.
Aggressive punch-outs, repeated maximum-throttle maneuvers and racing-style use should not be treated as the primary purpose of this battery.
A Strong 6S Battery for FPV Wings
FPV wings and other efficient fixed-wing aircraft can also make very effective use of this 6S1P pack. Once established in cruise, aerodynamic lift can reduce the continuous propulsion power required compared with a multirotor that must constantly generate lift.
That can allow the aircraft to make good use of the battery's 108Wh energy budget while the 50D platform provides useful additional power headroom for launch and climbing.
Battery-bay dimensions, launch current, installed weight and center of gravity should always be checked before choosing the pack.
XT60 Connector with 12AWG Power Leads
This SKU uses an XT60 main connector with 12AWG power leads, aligning it naturally with the connector ecosystem used by many long-range FPV, FPV wing and efficient 6S aircraft systems.
XT60 is an installation choice rather than the fundamental limit on battery performance. Cell capability, 6S1P architecture, internal connections, wire, connector, thermal conditions and actual aircraft load must all be considered together.
Compact 73.5 × 43 × 64.5mm 6S1P Pack
The finished battery measures approximately 73.5 × 43 × 64.5mm. Its 6S1P architecture packages six 21700 cells into a relatively compact form while retaining the full 108Wh energy of the cell stack.
Always measure the usable battery compartment before purchase and allow additional clearance for the XT60 connector, 12AWG wires, balance lead, securing system and cooling airflow.
6S1P vs Higher-Capacity 6S2P Li-ion Batteries
| Configuration |
Main Advantage |
Long-Range Direction |
| 5000mAh 6S1P |
Lower cell count, compact architecture and lower pack mass |
Long-range FPV, cinematic FPV and weight-sensitive 6S aircraft |
| 10000mAh 6S2P |
Twice the parallel capacity plus load sharing |
Larger FPV, cinematic and UAV platforms capable of carrying more battery mass |
Moving to 2P provides significantly more stored energy and current sharing, but also doubles the number of cells. The best endurance choice is therefore the configuration that gives the aircraft the most useful energy without pushing battery mass beyond its efficient operating point.

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 a 6S Li-ion battery and a 6S LiPo or LiHV battery use identical charging, warning or low-voltage cutoff settings. Confirm the chemistry and actual operating voltage requirements before use.
Inspect the pack, wiring, XT60 connector and wrapping before charging or flight. Do not use a battery that is damaged, excessively hot or electrically abnormal, and never exceed the finished battery's appropriate voltage, current or thermal limits.
During initial aircraft setup, monitor propulsion current and battery temperature under realistic flight loads to confirm that the complete system remains within an appropriate operating range.
