Description
EVE INR21700 58E 5700mAh 3.6V 16.8A High-Capacity Lithium-ion Battery Cell
One of the highest capacity 21700 lithium-ion cells available today. Units are limited !!
The EVE 58E is the absolute top-tier 21700 lithium-ion cell when it comes to capacity and energy density. With a true 5700mAh and 20.5Wh per cell, it outperforms Samsung 50E, Samsung 50G, and LG 58E in both total capacity and watt-hour output.
This is currently the best high-capacity 21700 cell available — no other cell on the market offers this level of runtime, making it perfect for long-range e-bike builds, scooters, and power-dense battery packs. Fewer cells are needed to achieve the same runtime, saving weight and reducing complexity.

⚠️ Important Safety Notes
Never solder directly to the battery cell. Always use spot welding. Always include a proper Battery Management System (BMS).
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 even 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's 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.
