Offerings: tiers and cell grades

Commercially, you’re buying a package: usable energy tier + cell grade. That keeps quoting clean and keeps expectations aligned.

Offering Usable energy Primary objective Typical buyer profile
Saver ~7 kWh
usable energy target
Reliability-first at minimum total cost “Get my Volt back on the road and keep it there.”
Standard ~14 kWh
usable energy target
Balanced daily-driver performance “I want OEM-like behavior with modern cells.”
Extended ~28 kWh
usable energy target
Maximum EV miles / headroom “I want the biggest swing in electric-only driving.”
Cell grade Commercial posture Engineering intent
Bargain Cost‑first Lowest capex. Appropriate when power headroom is not the driver.
Standard Balanced Best value: stable delivery, sensible thermals, strong lifecycle economics.
Elite Performance‑first Highest power capability and best thermal posture — the “no excuses” option.

Compatibility target: 2011–2015 Chevy Volt and 2014–2016 Cadillac ELR. Actual usable energy varies by configuration and calibration.

One PDF with every graph, packaged for sharing.

How to sell this: attach the PDF, then point to 2–3 graphs that answer the buyer’s core fear. Fear is usually heat, sag, or capacity drop — not the spec sheet.
