How to Source Air Bar Zen 4: Lithium Battery Documentation
Published 2026 · VapeWholesaleHub trade desk
Lithium battery documentation is the single most common cause of a held Zen 4 shipment.
Between the factory gate and the retail shelf, lithium battery documentation is where most of the value on the Zen 4 is either created or lost.
Consistency across batches matters more than peak performance for Zen 4, and lithium battery documentation is where inconsistency first appears.
Why lithium battery documentation matters on the Zen 4
Test summaries, packing declarations and correct labelling must travel with the consignment.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen 4.
State of charge limits apply to air freight and should be confirmed before booking.
