The one number on a robot battery pack datasheet that changes its DOT shipping section
Learn how to calculate a robot battery pack's watt-hours, pick Section IA, IB, or II, and get the packaging, labels, and UN 38.3 evidence right before shipping.
Compliance, Certification & Transport Regulation
Verifying battery certifications and applying UN 38.3, UL, FCC, DOT/PHMSA, and fire-code requirements to robotic pack procurement.
Eight UN 38.3 tests, and whether the summary covers your pack
Read a UN 38.3 test summary as a document about one pack configuration. Check the cell, BMS, enclosure, and internal construction against your purchase order.
UN 38.3 is not IEC 62133-2, and robot packs often need both
UN 38.3 covers transport, IEC 62133-2 or 62619 covers product safety, and an NRTL file covers the US mark. Build all three in this order for an AMR pack.
What Does a Freight Forwarder Need From a UN 38.3 Summary?
A UN 38.3 summary is a transcription source, not a filing artifact. What the forwarder's desk actually reads, and what to settle before the first pack ships.
How to Read a UN 38.3 Test Summary Before Accepting a Battery Pack
A line-by-line way to check a UN 38.3 test summary against the battery pack in front of you: model designators, T1-T8, report numbers, and change triggers.
The Eight UN 38.3 Tests Behind Your Robot Pack's Test Summary
A UN 38.3 test summary for a robot battery pack is a verification document. Check the test list, the tested configuration, and what voids it before you buy.
The DOT Rules for Shipping Damaged Lithium Batteries Most Shippers Miss
Damaged and recalled lithium battery packs leave the small-battery exception: PG I packaging, no air, and a shipping paper. Build an RMA return that clears.
What a UN 38.3 Test Summary Must Show Before DOT Shipping
How buyers read a UN 38.3 test summary as a DOT shipping prerequisite: matching pack part numbers, cell types, and Wh ratings before freight is booked.
Your BMS Module's FCC ID Covers the Module, Not the Pack
An FCC ID on a wireless BMS module authorizes the module, not the pack. Here is how buyers separate the module grant from the host integration obligation.
Does your robot pack need IEC 62133-2 certification?
IEC 62133-2 is a procurement artifact, not a lab result. How to carry the certificate from an RFQ evidence list to the part file — and keep it from going stale.
