Description
Linkdata 21700S-65P Battery Cell – 6500mAh 52A – In Stock High Capacity High Power Cell
Now available in the USA: the Linkdata INR21700S-65P ultra high capacity and high current lithium-ion battery cell. This cell is designed for applications that demand maximum runtime while still delivering strong power output in a single platform.
The 65P combines a true 6500mAh typical capacity with the ability to deliver up to 52A continuous discharge, making it a powerful option for builds that need both high energy density and reliable current capability.
This unique combination allows builders to reduce parallel groups while still achieving high output, improving efficiency, reducing weight, and minimizing voltage sag under load.
With very low internal resistance and strong thermal stability, the 65P performs consistently under demanding conditions, making it ideal for serious high-performance builds.
Applications include:
- High-performance e-bikes and scooters
- Custom battery packs
- RC and robotics applications
- Energy storage systems
- High-current projects where both capacity and power are required

Safety Warning for Lithium Ion Battery Usage
Customers should have a clear understanding of lithium ion battery handling and safety before making a purchase. Lithium ion batteries are highly sensitive and may pose fire, burn, or explosion risks if improperly handled. Always charge batteries on fire resistant surfaces, and never leave them charging unattended.
By purchasing, you assume full responsibility for any injury, damage, or loss arising from the incorrect use or handling of lithium ion batteries or chargers. Compatibility with specific devices is not guaranteed. Only charge using a smart charger designed specifically for this battery type, and do not mix old or used batteries with new ones.
Important Usage Guidelines:
- Not for use in e-cigarettes or similar devices. Lithium ion batteries present a serious risk of injury, property damage, or death if improperly used.
- Risk of fire and explosion. Misuse can cause batteries to ignite, explode, or release harmful gases.
- Always use in a protected pack. Ensure batteries are used within intended specifications and supported by appropriate circuitry.
- Proper storage and handling. Store batteries in protective cases, away from metal items to prevent short circuits.
- Inspection prior to use. Do not use batteries with damaged wrappers, torn insulators, or visible damage.
- Follow manufacturer charging specifications. Avoid overcharging or over discharging, and never alter, dismantle, puncture, crush, or burn.
- Heat and water precautions. Do not expose batteries to high temperatures or any liquids.
- Assembly guidelines. Batteries should only be spot welded. Do not solder directly onto battery terminals.
Users are expected to have battery handling knowledge before purchasing. By using these batteries, you acknowledge that usage is solely at your own risk, and you take full responsibility for any resulting consequences.
For resellers: Please ensure all safety information is passed along to end users to promote safe handling and proper use.
Orders ship from Florida when inventory is available. Lithium-ion cells require proper handling, protected packs, correct chargers, and safe storage. Do not solder directly to battery terminals.
