Transportation:
1).To ensure battery safety during delivery, SOC( state of charge) must be below 35%,inside temperature of container could not be over 35°C. Product holder should be responsible for any possible loss during delivery if above conditions cannot be met completely.
2),Inside temperature of container must be below 20°C if any client requires SOC(state of charge)above 35%,the distance between battery master cartons should be not less than 10cm in container, and coercive air cross ventilation system is required in container to ensure even temperature for each master carton. Product holder should be responsible for any possibly accidental loss if above conditions cannot be met completely.
