Battery Pack Storage and Transportation:


1) Storage
If the battery pack has to be stored for a long period (1 months above), the battery pack must have retained 50% of the capacity before storage (recharge the battery pack by equipped charger for 2-3 hours after each fully discharge),and must stored at dry, ventilated place. The battery pack must have been recharged for 1-2 hours in every 3 months.

2) Transportation
Battery pack and charger must be packed well before sending for shipment. The packed goods can be shipped by road,
railway, vessel, and airplane. The SOC (state of charge) of the battery pack shall be at between 40-60% during
transportation, and violent mechanical pulse, sun exposure, rains, upside down are prohibited during transportation.
The battery pack must be well treated during uploading and unloading.
