Why Battery Pack Engineers Choose the Samsung 50S
Engineered for Demanding Battery Pack Applications
More Energy for Longer Runtime
Deliver 5Ah-class capacity in the compact 21700 format for applications that need longer operating time without dramatically increasing pack size.
01
Power for Demanding Loads
A manufacturer-rated 25A maximum continuous discharge capability supports professionally engineered packs for power-demanding equipment.
02
Low Initial Impedance
Low initial AC impedance helps reduce electrical losses and supports efficient current delivery when properly integrated into the battery pack.
03
Balanced Power-to-Energy Performance
The 50S provides a practical balance between energy-focused cells and lower-capacity high-power cells.
04
Industrial Pack Integration
Suitable for professionally engineered packs incorporating appropriate BMS, over-current protection, insulation and thermal management.
05
Application Scenarios
FAQ
Are your INR21700‑50S cells 100% original Samsung SDI stock? Can you provide traceability documents?
Yes, we supply genuine Samsung SDI INR21700‑50S sourced via authorized distribution channels. Full batch traceability, original factory COO, MSDS, UN38.3 and IEC62133 certificates are available for B2B customers. We do not offer refurbished, used or counterfeit cells. Third‑party sample testing is welcomed for mass‑order validation.
What are the key performance parameters of INR21700‑50S, and what applications is it best suited for?
Typical capacity 5000 mAh (min 4800 mAh), nominal 3.6 V, max continuous discharge 45 A, flat‑top NCA high‑power cell. Ideal for high‑drain projects: power tools, drone, e‑scooter, AGV, portable power station and high‑current battery pack assembly. Not recommended for low‑rate stationary energy‑storage only.
What is your MOQ, lead‑time and can you supply matched‑grade cells for pack production?
Samples are available for prototype testing. Production MOQ follows original carton standard. For bulk orders, we offer IR‑sorted & capacity‑matched cells for multi‑series‑parallel pack builds. Stock items ship within 3‑7 working days; allocate‑order lead‑time depends on Samsung SDI production schedule. Volume‑based pricing tiers are available.
What is the warranty policy for Samsung INR21700‑50S cells from your distribution?
We follow Samsung SDI original factory warranty against manufacturing defects. Warranty does NOT cover damage caused by over‑charge, over‑discharge, short‑circuit, improper pack design or misuse. For quality claims, customers need to provide batch code, test data and failure samples for assessment.
Can you support OEM or pack‑building service, and do you offer export documentation?
Besides bare cells, we support technical consultation for battery pack integration. We provide complete export documents including shipping declaration, dangerous‑goods paperwork for sea / air shipment. Custom labeling and neutral packing can be arranged upon volume requests.
