Key Specifications
Model: Pro-Range NMC 18650
This battery pack is built using Pro-Range NMC (Nickel Manganese Cobalt) 18650 cells, which are widely recognized for their balance between energy density, power output, and safety. NMC cells are favored in industries such as drones, electric vehicles, and power tools because they deliver consistent performance while reducing overheating risks.
Nominal Voltage: 3.7V
The nominal voltage of 3.7V is the standard operating voltage for lithium-ion cells. This makes the battery pack highly compatible with a wide range of electronic circuits, controllers, and power systems. Devices that require a stable 3.7V input — such as drones, IoT modules, and RC devices — can operate efficiently without complex power regulation.
Fully Charged Voltage: 4.2V
When fully charged, the battery reaches 4.2V per cell. This is the maximum safe voltage recommended for lithium-ion batteries. At this level, users get peak capacity and maximum runtime from their devices. A properly managed charging system (BMS or smart charger) ensures safe charging without exceeding this limit, which extends the lifespan of the pack.
Capacity: 5000mAh
With a capacity of 5000 milliampere-hours (mAh), the battery pack can deliver 5 amps of current for one hour, or proportionally lower current for longer durations. In practical terms:
- Drones get longer flight times before needing a recharge.
- RC vehicles enjoy extended usage without frequent battery swaps.
- Tools and electronics benefit from consistent energy delivery over long sessions.
The large capacity makes this pack ideal for high-demand, endurance-based applications.
Configuration: 1S2P (1 series, 2 parallel cells)
The pack uses a 1S2P configuration, meaning:
- 1S = one cell in series → voltage remains at 3.7V nominal (4.2V max).
- 2P = two cells in parallel → doubles the capacity to 5000mAh while maintaining the same voltage.
This design ensures a balance of voltage stability and increased capacity, making the pack powerful yet compact. For drones and handheld tools, this configuration offers an ideal trade-off between size, weight, and energy storage.
Discharge Rate: 8C (up to 40A continuous discharge)
The discharge rate (C-rate) indicates how quickly the battery can safely release stored energy. An 8C rating means the pack can continuously discharge at 8 times its capacity:
- 5000mAh × 8C = 40A continuous output.
This high discharge current is crucial for high-drain devices:
- Drones need sudden power bursts during takeoff and rapid maneuvers.
- RC cars require strong discharge for fast acceleration.
- Power tools rely on stable high-current supply to maintain torque.
Thus, the 3.7V 5000mAh Li-Ion Battery Pack ensures performance under stress without voltage drops.
Rechargeability: Supports Multiple Charge Cycles
Lithium-ion technology allows this battery pack to be recharged 500–800 times (with proper care) before noticeable capacity loss. This makes it a cost-effective and sustainable choice compared to disposable alternatives.
For long-term reliability:
- Always use a dedicated Li-ion charger.
- Avoid overcharging or deep discharging.
- Store partially charged (~40–60%) if not in use for extended periods.
Applications: Drones, RC Vehicles, Tools, EV Components
The 3.7V 5000mAh Li-Ion Battery Pack is versatile and widely used in:
- Drones & UAVs → longer flights, stable power, lightweight energy storage.
