Shops that receive a short briefing on lithium battery documentation convert noticeably better than shops that only receive stock.
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.
