- Custom high-current lithium-ion battery packs
Important Safety Information
- This is an unprotected industrial cell intended for qualified battery-pack assembly.
- The 60A rating requires active temperature monitoring and an 80°C cell-temperature cut-off. The pack must also include suitable BMS, fuse, insulation, current protection, and thermal management.
- Do not short-circuit, overcharge, over-discharge, reverse polarity, puncture, crush, disassemble, or expose the cell to fire or excessive heat.
- Do not use cells with damaged insulation, dents, corrosion, leakage, unusual odor, or abnormal heat.
- Use matched cells of the same model, batch, capacity, voltage, and internal resistance when assembling a battery pack.
- Pack design, cell matching, welding, charging, storage, transportation, and operation must be handled by qualified personnel.
- Not intended for direct consumer use or e-cigarette/vaping devices.
All specifications are nominal or laboratory-tested values. Verify the latest manufacturer datasheet, production batch, load profile, charging strategy, thermal design, and applicable regulations before use.
Package quantity is supplied according to the option selected at checkout. Product printing and batch codes may vary.
