Product Details
The GEB 14.8V 4S 5000mAh 25C High-Rate LiPo Battery Pack is an engineered Lithium Polymer (LiPo) power solution manufactured specifically for high-thrust aerial vehicles. Delivering a 14.8V nominal working voltage (3.7V per cell × 4S) and 5,000mAh rated capacity (74.0Wh energy), it sustains 25C continuous discharge (125A continuous load) with peak bursts up to 50C (250A ≤ 5s). Built with laminated pouch foil stacking and ultra-low internal impedance, it prevents steep voltage sag under heavy collective pitch demands on 500–600 class RC helicopters, surveying quadcopters, and cinematic UAV platforms.
Product Overview
The GEB 14.8V 4S 5000mAh 25C LiPo Battery Pack combines high gravimetric energy density (~150Wh/kg) with high continuous discharge stability. Unlike standard cylindrical steel cans, this pack utilizes precision stacked polymer pouch cells enclosed in heavy-duty impact-resistant PVC heat shrink with internal aluminum heat-shielding plates. Weighing Approx. 495g and measuring 138 × 44 × 34 mm, it features factory-fitted high-flexibility 10AWG silicone discharge cables terminated with genuine XT90 or XT60 connectors, alongside an industry-standard JST-XH 5-pin balancing connector for cell-by-cell voltage management.

Integration & Operational Boundary Conditions
Balance Charging Mandate: Always connect both the primary power leads and the JST-XH balance lead to an authentic balance charger. Cell delta voltage must remain within ≤ 20mV across all four cells.
In-Flight Low Voltage Telemetry: Calibrate UAV flight controller battery voltage alarms to sound low-voltage warning at 3.60V/cell (14.4V) and trigger automatic Return-To-Land (RTL) at 3.50V/cell (14.0V) under throttle load to maintain pack longevity.
Storage Voltage Maintenance: Never store high-rate LiPo packs fully charged (4.20V/cell) or depleted (< 3.60V/cell) for more than 48 hours. Discharge or charge each cell to 3.82V–3.85V using the charger’s Storage function.
Equipment Compatibility & Engineering Fit Check
Before deploying GEB 14.8V 4S 5000mAh 25C High-Rate LiPo Battery Pack for RC Helicopters & Drones, verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Industrial UAVs, FPV platforms, and robotics requiring rapid burst response at 14.8V.
- Flight missions needing high energy density and stable voltage plateaus under heavy payload draw.
- Applications demanding verified Class 9 / UN38.3 compliance for commercial field logistics.
⚠ Operational Constraints & Limits:
- Do not discharge below minimum cutoff voltage or charge beyond 16.8V.
- Maintain operational surface temperature within -20°C to +60°C discharge (0°C to +45°C charge).
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
