Key Features
1. High Energy Density
- INR18650-35E Cells: Samsung's Nickel-Manganese-Cobalt (NMC) chemistry delivers 3500mAh per cell, with two cells in parallel (2P) providing 7000mAh total.
- Compact Design: Four cells in series (4S) yield 14.8V (3.7V/cell × 4), balancing voltage and capacity in a standard 18650 form factor.
2. Long Cycle Life
- Durability: Samsung's cells typically offer 500-1000 charge cycles (80% capacity retention after 500 cycles), ensuring longevity in demanding applications.
3. Advanced Battery Management System (BMS)
- Safety Features: Overcharge/over-discharge protection, short circuit prevention, thermal management (shutdown at high temperatures)
- Cell Balancing: Maintains uniform charge across all cells, maximizing capacity and lifespan.
4. Fast Charging
- Rapid Recharge: Supports 1C-2C charging (7-14A), achieving 0-80% charge in 30-60 minutes with a compatible charger.
- Charging Efficiency: High conversion rates reduce energy loss during charging.
5. Wide Temperature Tolerance
- Operating Range: -20°C to 60°C (performance may degrade in extreme cold).
- Thermal Stability: NMC chemistry resists thermal runaway better than some lithium chemistries.
6. Versatile Applications
- Power Tools: Cordless drills, saws, and impact wrenches.
- Drones & RC Vehicles: High-power drones requiring sustained voltage under load.
- Portable Electronics: High-drain devices like portable projectors or LED spotlights.
- Robotics: Powering industrial or hobbyist robots with demanding power needs.
