Precaution

  • Lithium batteries are shipped at a 50% state of charge. Fully discharged battery packs must not be loaded for further discharge or used directly in operation.
  • Storage Conditions: Store in a dry environment with temperature ≤30°C and relative humidity ≤75%. Maximum storage duration: 5 years. Keep away from acids or other corrosive substances.
  • Long-Term Storage Maintenance: For batteries unused for over 6 months, perform at least one charge-discharge cycle (0.5C5A rate) before returning to 50% charge for continued storage.
  • The charging environment temperature should be strictly controlled to be between 0℃ and 45℃. The discharging temperature is between -40℃ and 55℃, and the storage temperature should not exceed 40℃.

Frequently Asked Questions

What are the main application areas for these batteries?

These batteries are designed specifically and mainly applied to outdoor equipment environments requiring stable performance under varied temperatures.

What is the standard cycle life of these lithium battery packs?

Both the 8Ah and 20Ah capacity configurations support a cycle life of at least 500 standard charge-discharge cycles.

How should the battery be stored for long periods?

Keep it in a dry space with temperatures ≤30°C and relative humidity ≤75%. If unused for over 6 months, run one full charge-discharge cycle and return it to a 50% charge state.

What is the safe operating temperature range?

The charging environment must remain between 0℃ and 45℃, while discharging operations can run between -40℃ and 55℃ (or up to 60℃ for the 20Ah model).

Can I discharge the battery pack completely before recharging?

No, fully discharged battery packs must not be loaded for further discharge. Keep the charge-discharge guidelines strictly in place to maintain overall battery safety and health.
