BAK N21700CG-50E 5000mAh 15A - New
BAK N21700CG-50E Li-Ion Battery Cell 5000mAh 15A
The high-quality BAK N21700CG-50E lithium-ion battery cell in the popular 21700 format offers a capacity of 5000mAh and a maximum continuous discharge current of 15A. Thanks to its high capacity and stable performance, it is ideal for battery packs, energy storage systems, backup power supplies, mobile devices, consumer electronics, and DIY projects.
Manufactured using advanced Hi-Ni Li-Ion technology, the cell provides high energy density, low internal resistance, and long cycle life. It is designed for professional applications requiring a reliable power source and consistent performance.
Applications:
- Energy storage systems
- Battery pack assemblies
- UPS and backup power systems
- Electronic devices
- Robotics and automation
- DIY projects
- Mobile equipment and smart devices
Important Notice:
This battery cell does not include a built-in protection circuit (PCB/BMS). Appropriate protection systems must be used when assembling battery packs.
The discharge current when working in packs (a battery composed of many 18650 or 21700 cells) is lower than the current specified in the catalog note for one cell. This is due to the fact that many cells in the pack heat up from each other. The increased and uneven temperature of the pack causes rapid degradation of the cell and such a battery may not survive even one season. For the safety and long life of your battery, always design it safely based on the maximum operating current in the pack. Do not overload the cells, do not build a pack based on the maximum current for 1 cell - otherwise your pack will have a very short lifespan.
The stated internal resistance of the cell is based on the manufacturer’s official datasheet. This value is declared by the manufacturer and may differ from the result obtained when measuring an individual cell.
