Adding a Second Pack Supplier Without Paying Two Minimums
Splitting volume across two pack assemblers duplicates qualification and tooling, and usually the minimum. Here is the arithmetic, and how to structure around it.

Seven linked decisions, from voltage window to capacity and peak current: what each one does to the quote a pack builder can actually give you.
Read an ISO 9001 certificate line by line: scope wording, certified site address, accreditation mark, validity dates, and suspension status before you trust it.
Filing certificates by document type breaks at the first pack revision change. How to run compliance evidence as a versioned, indexed, retained document set.
Move a custom lithium-ion pack from pilot build to mass production with documented gates: process capability, documentation, capacity, and commercial readiness.
Payment terms on custom battery packs work as a program-risk tool. A gate-by-gate framework for NRE, tooling, pilot, and mass production money.
Second-source qualification is a schedule problem. Start while the primary is healthy, and qualify the alternate to the same drawing revision and test limits.
How to read a pack supplier's QMS as sourcing evidence: scope statements, control plans, traceability records, and the gaps that surface in custom assembly.
Why a first article approval, written cell substitution control, and traceability validation decide whether your pilot build means anything in mass production.
A second lithium-ion pack source needs its own audit and its own pack-level validation. Everything upstream of the pack can be inherited from the first.
