On January 1, 2026, the 67th edition of the dangerous goods rules of the International Air Transport Association came into effect. In this version of the rules, the most concerned by the lithium battery industry is the overall tightening of the state of charge (SoC) restrictions-from this day on, all lithium ion batteries packaged with equipment, when delivered for air transportation, the state of charge shall not exceed 30% of the rated capacity..

The impact of this regulation is far greater than it seems. According to the packing instructions PI966, for the case of UN3481 "lithium ion battery packed together with equipment", if the battery energy exceeds 2.7Wh, if the state of charge exceeds 30%, you need to obtain the approval of both the country of origin and the country of the airline to arrange transportation.. For PI967 "lithium ion battery installed in equipment", although there are still suggested measures at present, IATA explicitly recommends that the state of charge should not exceed 30% or the display power of the equipment should not exceed 25% during transportation..

Dongguan Juneng New Energy Technology Co., Ltd.'s practice in the field of lithium battery PACK customization is worth reference. In the design stage of portable energy storage power supply, industrial equipment battery pack and other products, the company takes the SoC control strategy of BMS into consideration to ensure that battery pack can meet the transportation compliance requirements of the target market when leaving the factory. Taking the portable energy storage power supply for the US market as an example, the customized solution for gathering energy new energy adopts a combination of lithium iron phosphate batteries, 12S or 14s, and the rated energy is 2400Wh. In the design stage, it is directly based on UL2743, FCC, CE, UN38.3, RoHS, REACH, and California 65 standards are verified and are compatible with SoC limits for air transportation.

Energy gathering new energy he has more than 10 years of experience in battery pack structure design, thermal management application and waterproof technology, covering many fields such as electric bicycles, solar equipment, robots, AGV cargo van, etc. For those equipment manufacturers whose products need to be exported overseas, it is much more cost-effective to choose a PACK partner who can advance the transportation compliance requirements to the design stage than to find a temporary solution before shipment.
