Applications
The INR21700/58E works well in battery pack applications such as:
-
E-bikes, e-scooters, and light electric vehicles
-
Power tools, garden tools, and cordless equipment
-
Portable power stations and outdoor backup power
-
Home energy storage and industrial battery packs

Custom 21700 battery packs for OEM/ODM projects
Final performance depends on pack design, BMS, thermal management, and charging profile.
Pack Design Notes
For best results, use a proper BMS and thermal design. Keep cells away from heat sources and high-temperature components.
Recommended cell spacing is more than 1mm. Use shock absorption and insulation protection. Do not solder directly to the cell. Weld connectors only to the designated terminal areas.
These practices help maintain cell performance, safety, and cycle life.
Safety and Transport Testing
The EVE INR21700/58E is tested under methods referenced to IEC62133, UL1642, and UN38.3. Tests include overcharge, external short circuit, forced discharge, heating, low pressure, vibration, and free fall.
Criteria include no fire, no explosion, and in some tests no leakage and limited OCV drop. Cells are shipped at <30% SOC and 3.400–3.600V to support safer storage and transport planning.
