Product overview
The CNHL Long Range Series 5000mAh 14.4V 4S 21700 Li-ion Battery with XT60 is a rechargeable power pack for long-range FPV, FPV wings and efficient fixed-wing aircraft. Four BAK INR2170-50D cylindrical cells connect in series, forming a 4S1P assembly with 72Wh nominal energy. The complete battery includes wrapping, an XT60 main connector, 12AWG power leads and balance wiring. Its design balances stored energy with usable power capability, while retaining a single cell path for propulsion current.
The pack measures approximately 73.5 × 43 × 43mm (2.89 × 1.69 × 1.69in). The pictured production sample weighs approximately 292.5g / 0.65lb and provides approximately 246Wh/kg at the finished-pack level. Installation needs additional room for the connector, power leads, balance wiring, securing straps and ventilation. Aircraft integration also depends on compatible weight, center of gravity, voltage and propulsion current. Flight endurance varies with aircraft efficiency, propulsion setup, wind, payload and usable depth of discharge.
The underlying BAK 50D cells allow up to 5C without a temperature cutoff, corresponding to a 25A cell-level test condition. The higher 8C, 40A cell-level condition requires the specified 70°C temperature cutoff; 40A is not an unrestricted continuous rating for the finished battery. Practical capability also depends on wiring, interconnections, cooling and load duration. The pack is not intended as a direct high-C LiPo replacement for racing or aggressive freestyle. Charging requires a suitable Li-ion charger and mode, with a maximum of 16.8V per pack, or 4.20V per cell.
