Buyer guide
BESS acquisition due diligence checklist for buyers who want the battery story tested before close
This is the practical checklist behind a stronger battery acquisition review. It exists to keep buyers focused on condition, risk, and usable reality instead of getting lost in tidy data-room cosmetics.
The checklist
1Request raw or near-raw BMS exports, not only summarized dashboards
2Test usable capacity versus BMS-reported State-of-Health
3Review degradation mode evidence, not just capacity headline numbers
4Check thermal asymmetry, imbalance, and transition behavior
5Review telemetry quality, missing windows, and timestamp integrity
6Confirm warranty posture and unresolved claims history
7Test whether the operating reality supports the revenue case
8Decide what needs SPA protection, pricing adjustment, or post-close monitoring
