Reliance INR21700-RS50 5000mAh 70A 21700 Battery
The Reliance INR21700-RS50 is a powerful 21700 lithium-ion cell for applications where high capacity and high discharge current are equally important. With a typical capacity of 5000 mAh, 3.6 V nominal voltage and a discharge current of up to 70 A under suitable thermal conditions, this cell is made for demanding high-drain applications.
Thanks to its combination of high capacity, reduced voltage drop under load and flat-top design, the RS50 is an interesting choice for battery packs, e-bikes, scooters, power tools, drones and other systems that require reliable performance from a compact 21700 cell.
Important note: This cell is unprotected and only suitable for users who know how to handle high-drain Li-ion cells safely. Please use it only in suitable devices, battery holders or battery packs with proper protection and charging electronics. Do not carry it loose in pockets and always protect it from short circuits, damage, heat and moisture.
