The GNB 4000mAh 4S1P 14.8V 70C Lipo Battery delivers an outstanding balance of energy density and instantaneous high-amp output, making it the premier choice for professional UAV pilots.
Sustained 70C High-Amp Performance :
Featuring matched, low-impedance chemical cells, this 4S battery pack effortlessly handles a true 70C continuous current delivery. Capable of driving sudden burst loads up to 140C, it supplies high-capacity FPV drone platforms with the raw throttle authority needed to lift heavy cinema cameras or recover smoothly from high-speed dives.
Optimized Energy Density to Weight Ratio :
When building enterprise mapping platforms or cinematic multirotors, optimizing every gram of weight is vital. This 4000mAh pack packs an incredible amount of capacity into a compact, tightly wrapped block, keeping your total takeoff weight low to maximize motor efficiency and significantly extend your overall airborne time.
Heavy-Duty 10AWG Wiring and XT90 Interface :
To ensure safe, high-current delivery without creating restrictive resistance bottlenecks, the pack comes pre-soldered with premium 10AWG high-flex silicone wire. It includes a genuine, high-temperature XT90 discharge connector with an integrated anti-spark sleeve, alongside a standard JST-XH balance lead for precise cell monitoring.
Target Aviation Flight Platforms :
An exceptional primary upgrade option for performance multirotors, including:
5-inch, 6-inch, and 7-inch heavy-lift cinematic FPV drones carrying action or mirrorless cameras
Long-endurance commercial mapping UAVs and autonomous inspection quadcopters
Large-scale 3D aerobatic RC balsa airplanes and tactical unmanned systems

Frequently Asked Questions :
Q1: What are the main benefits of using an XT90 connector on this 4S 4000mAh pack?
Ans: High-capacity 4S batteries hold significant potential energy that can create an electrical arc (spark) when connected to a drone's power board. The pre-installed XT90 connector safely manages heavy current draws up to 90A+ continuously without overheating or creating connectivity degradation.
Q2: What is the ideal charge rate to keep this 4S battery pack healthy?
Ans: For maximum cell longevity and long-term safety, we strongly recommend balance charging this pack at a 1C rate (4.0A). If you are in a rush at the flying field, it can safely handle fast-charging cycles up to 3C to 5C (12.0A to 20.0A) on a smart balance charger.
Q3: At what voltage should I land my drone to avoid over-discharging the battery?
Ans: To protect the internal lithium chemistry from permanent cell damage or swelling, set your telemetry low-voltage warning to 3.5V per cell under flight load (14.0V total for 4S) and land immediately before the resting voltage settles below 3.7V per cell.
Q4: How should I store this battery pack if my flight plans change?
Ans: Never leave a high-capacity 4S pack fully charged or completely depleted for more than 48 hours, as doing so can trigger cell swelling. Use your charger's storage cycle to bring the cells to a safe resting state of 3.80V to 3.85V per cell.
