BAK 18650 3.6V 3C Li-Ion Battery – High Performance Cell for Robotics & EV
The BAK 3C 3.6V 18650 Lithium-Ion Rechargeable Cell is a high-performance battery designed for high current applications such as robotics, electric vehicles, and power tools. Built using NMC lithium-ion chemistry, it offers excellent energy density, stable output, and strong discharge capability.
Unlike standard 1C cells, this 3C-rated battery can safely deliver significantly higher current, making it ideal for motor-driven systems and heavy-load electronics. Typical capacities range from 2500mAh to 3350mAh, providing a balance between power output and runtime.
The standard 18650 form factor (18mm × 65mm) ensures compatibility with battery holders, pack assemblies, and chargers.
