Cell Matching and Binning for PACK Consistency
Why capacity and IR binning decide whether a PACK balances quietly or fights itself for years.

Executive summary
Why capacity and IR binning decide whether a PACK balances quietly or fights itself for years.
What buyers should verify first
A PACK is only as consistent as its weakest cell group. Ask suppliers for capacity and internal-resistance windows used at module build—not only average cell grade marketing names.
Engineering and operations notes
Tight bins cost more but reduce balancer workload and early warranty noise. Loose bins look cheaper until field imbalance appears.
Practical rollout tip
Request sample IR histograms from the lot allocated to your PO.
Buyer checklist
Put temperature, load profile and protocol into the RFQ.
Request certificates and traceability for the exact PO model.
Pilot before fleet rollout.
FAQ
Can balancing fix poor matching?
Only within limits. Chronic imbalance usually traces back to wide bins or mixed lots.
