What is inside the Rivian R1T Large Pack battery pack
The Rivian R1T Large Pack carries a 135 kWh pack built from NMC 811 Cylindrical 2170 cells arranged in 9 serviceable modules at a nominal 400 V. Pack mass lands near 756 kg including the enclosure, cooling plate, contactors and BMS harness.
Because the cells are NMC 811 (2170), the recoverable value profile is dominated by nickel and cobalt, with lithium and copper adding a meaningful second tranche. That decides whether a retired pack is worth repurposing, refining, or both.

Step 1 — Removing and shipping a commercial fleet pack
Large packs are removed at the depot with a forklift-rated battery table and the vehicle isolated under lock-out tag-out. Retired packs are UN 3480 or UN 3481 dangerous goods, so the pack must be below 30% state of charge and any deformation, swelling or thermal history declared before pickup.
Each pack travels in a rated crate or on a restrained pallet, with coolant drained and ports sealed. Depot retirements are batched against the fleet replacement schedule so collections line up with vehicle swaps.
- Share telematics SOH history if it is available
- Confirm forklift access and dock height at the depot
- Isolate high-voltage systems under lock-out tag-out
- Declare any pack involved in a collision
Step 2 — Module-level state of health grading
Each of the 9 modules is tested independently — a whole-pack SOH figure hides the spread that decides second-life eligibility. We run a full capacity cycle, DC internal resistance measurement and impedance spectroscopy.
Our degradation model for the Rivian R1T Large Pack shows how value falls with age. Measured results replace these estimates once the pack is on the bench.
| Service year | Modelled SOH | Grade | Residual value |
|---|---|---|---|
| Year 2 | 94.6% | A — BESS ready | USD 8,445 |
| Year 4 | 90.3% | A — BESS ready | USD 8,109 |
| Year 6 | 86% | A — BESS ready | USD 7,674 |
| Year 8 | 81.7% | B — Second life | USD 6,675 |
| Year 10 | 77.4% | B — Second life | USD 5,850 |
Step 3 — What you actually recover
For modules routed to refining, a pack of this size and chemistry typically yields about 14.6 kg lithium, 94.0 kg nickel, 11.6 kg cobalt and 46.6 kg copper.
At 80% SOH our model sends about 47% of the pack to second life, worth USD 3,774, and credits USD 2,554 for the remainder as black mass. Avoided emissions come to roughly 4,236 kg CO2.
Field note
Step 4 — Where to send it and what paperwork you get
Rivian R1T Large Pack packs are received directly at 7 intake sites in its markets, including Detroit, Michigan, Dallas, Texas, Toronto, Ontario, Monterrey, Nuevo Leon. From there, modules move to the nearest grading bench and refinery.
Every consignment closes with a certificate showing quantity processed, recovery percentages achieved and downstream vendor disclosure, in the form used for EU and US producer-responsibility reporting. Fleets retiring several Rivian R1T Large Pack units should book one consolidated pickup to cut per-pack cost.
