The CNHL Long Range Series 10000mAh 14.4V 4S2P 21700 Li-ion battery combines eight BAK 50D cells into a 144Wh extended-range battery for large FPV wings, efficient long-range aircraft and UAV systems using XT60. Its 4S2P architecture doubles the parallel capacity of the 4S1P 5000mAh platform while allowing electrical load to be shared across two cells in each parallel group.
At approximately 564g for the pictured production sample, the complete battery achieves approximately 255Wh/kg of finished-pack energy density. This figure includes all eight 21700 cells, pack construction, XT60 connector, 12AWG power leads and balance wiring.
Built around the BAK 50D Power + Energy Balance platform, this battery is positioned for larger endurance aircraft that need substantially more stored energy than a compact 1P pack while still benefiting from the greater current-sharing capability of a 2P configuration.

144Wh Extended-Range 4S2P Architecture
LI1000104S70XT60 uses eight BAK 50D cells arranged as 4S2P. Four series groups establish the 14.4V nominal voltage, while two cells in each group are connected in parallel to produce a total capacity of 10000mAh.
This results in 144Wh of nominal stored energy, twice the energy of the corresponding 5000mAh 4S1P 50D battery. The 2P architecture also allows load to be shared across two parallel cells rather than relying on a single cell path.
That combination makes the pack especially relevant to larger endurance aircraft where additional battery weight can be justified by substantially greater mission energy and parallel current sharing.
Approx. 255Wh/kg Finished-Pack Energy Density
The pictured production battery stores 144Wh while weighing approximately 564g. That corresponds to approximately 255Wh/kg of finished-pack gravimetric energy density.
This calculation includes all eight cells plus the complete pack assembly, XT60 connector, 12AWG wiring and balance lead. It therefore represents the energy-to-weight ratio of the actual battery installed in the aircraft.
The value is particularly useful when comparing battery architectures for long-range aircraft because higher total capacity only creates useful endurance when the additional watt-hours justify the extra battery mass.
Why 2P Matters: Capacity Plus Parallel Load Sharing
A 2P battery does more than double capacity. In each series group, two cells operate in parallel, allowing electrical load to be shared between them.
Compared with a 4S1P pack using the same BAK 50D cell, the 4S2P architecture therefore provides both twice the nominal capacity and greater pack-level current-sharing capability. This can be useful for larger aircraft with higher sustained electrical demand.
The finished battery still needs to remain within the limits of the cells, internal interconnections, wiring, connector and thermal conditions. Parallel count should not be treated as an unlimited discharge-current multiplier.
Powered by BAK 50D – Power + Energy Balance
The BAK 50D remains the Power + Energy Balance cell platform in the CNHL 21700 Long Range family. Its purpose is to combine substantial stored energy with more usable power headroom than an energy-first cell designed primarily around maximum Wh/kg.
In this 4S2P configuration, the advantages of the 50D are extended further because the propulsion load can be divided across two parallel cells in each group.
This makes the 10000mAh pack a natural step up for larger aircraft that need both extended endurance and more current-sharing capability than a compact 4S1P battery can provide.
10000mAh 4S Li-ion Battery for Large FPV Wings
Large FPV wings are one of the strongest applications for this 4S2P battery. An efficient wing can carry significantly more battery energy than a small multirotor while using relatively modest power during steady cruise.
With 144Wh available, this pack can support extended-distance and long-duration flights when the airframe has sufficient battery volume and can carry the 564g pack without compromising balance or aerodynamic efficiency.

Extended-Range Battery for Fixed-Wing Aircraft
Efficient fixed-wing RC airplanes can also make strong use of this battery when the airframe is large enough to benefit from its 144Wh energy capacity. Utility aircraft, endurance-oriented fixed-wing models and larger gliders can all be relevant applications.
The additional battery weight must still be evaluated carefully. A larger pack only improves useful flight time when the aircraft can carry it without losing too much efficiency or moving outside the intended center-of-gravity range.

4S Li-ion Battery for Mapping and Endurance UAVs
The 10000mAh 4S2P configuration also moves naturally into the UAV category. Mapping, inspection and other endurance-oriented aircraft can benefit from the combination of 144Wh mission energy and parallel load sharing when the complete aircraft is designed around the additional battery mass.
Fixed-wing UAVs are particularly well suited to this type of battery because efficient aerodynamic cruise can turn a large portion of the stored energy into useful range and mission time.

XT60 Connector with 12AWG Power Leads
LI1000104S70XT60 uses an XT60 main power connector with 12AWG leads. This makes it a natural fit for larger FPV wing, fixed-wing and UAV systems already built around XT60.
XT60 does not define the battery's fundamental discharge capability. The BAK 50D cell platform, 4S2P architecture, internal interconnections, 12AWG wiring, connector, cooling and actual operating conditions must all be considered together.
146 × 43 × 44mm Extended-Range Pack
The finished battery measures approximately 146 × 43 × 44mm. The 4S2P architecture essentially extends the pack length to accommodate eight 21700 cells while keeping width and height relatively compact.
Measure the usable battery bay before purchase and allow additional room for the XT60 connector, 12AWG power wires, balance lead, mounting straps and airflow. For fixed-wing use, always verify the final center of gravity with the 564g battery secured in its intended flight position.

The 4S2P battery doubles nominal energy from 72Wh to 144Wh while the pictured finished-pack weight increases by about 93%. Its main advantage is therefore not merely capacity but the combination of substantially greater mission energy and parallel load sharing for aircraft large enough to use it efficiently.

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 16.8V for this complete 4S battery.
Do not assume that a 4S Li-ion battery and a 4S LiPo or LiHV battery use identical charging, low-voltage warning or cutoff settings. Confirm the chemistry and appropriate voltage limits before use.
The 2P configuration provides load sharing across parallel cells, but finished-pack capability still depends on the cells, interconnections, 12AWG wiring, XT60 connector, cooling, ambient conditions and battery temperature.
During initial aircraft setup, monitor actual propulsion current and pack temperature under realistic operating conditions before relying on the battery for long-duration flights or missions.
FAQ: CNHL 10000mAh 4S 21700 Li-ion Battery with XT60
What cells are used in this battery?
