Where a MG Comet EV pack goes from Changsari, Assam
- 1
Intake at Changsari, Assam
One pack per UN-rated pallet box, strapped and restrained, with terminals capped and coolant ports sealed. Each pack is weighed, photographed and discharged below 30% state of charge.
- 2
Graded at Gurugram, Haryana
Modules travel 1,463 km to NCR — Gurugram Collection & Grading Hub for capacity, resistance and impedance testing across all 6 modules.
- 3
Second life at Butibori, Maharashtra
At 80% SOH about 56% of the pack qualifies for reuse and goes to Nagpur — Butibori Second-Life Works (1,425 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refined at Haldia, West Bengal
Remaining modules are shredded to black mass and refined at Kolkata — Haldia Refining Works, 592 km away.
| Stage | Facility | Distance |

| Nearest grading bench | NCR — Gurugram Collection & Grading Hub | 1,463 km |
| Nearest second-life works | Nagpur — Butibori Second-Life Works | 1,425 km |
| Nearest refinery | Kolkata — Haldia Refining Works | 592 km |
Inside the MG Comet EV battery
The MG Comet EV (2023) carries a 17.3 kWh LFP Prismatic (LiFePO4) pack with 6 modules at 280 V, weighing roughly 128 kg. Cobalt-free prismatic chemistry dominant in Indian passenger EVs and commercial fleets. Low black mass value, exceptional second-life economics.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 96.3% | A — BESS ready | USD 908 |
| Year 4 | 93.2% | A — BESS ready | USD 880 |
| Year 6 | 90.1% | A — BESS ready | USD 851 |
| Year 8 | 87% | A — BESS ready | USD 823 |
| Year 10 | 83.9% | B — Second life | USD 706 |
What the chemistry means here
How it ages
LFP fades slowly and fairly linearly for most of its life. Capacity loss is driven mainly by lithium inventory being locked up in the SEI layer on the graphite anode, while the cathode structure stays largely intact.
Thermal behaviour
LFP's olivine cathode holds its oxygen tightly, so thermal runaway typically starts at higher temperatures than nickel-rich cells and releases noticeably less heat. It is not inert: a failing LFP cell still vents flammable electrolyte vapour and hydrogen, and large prismatic cans store a lot of energy in one place.
Handling LFP Prismatic
Collecting a MG Comet EV pack
17.3 kWh, 6 modules, about 128 kg — this is how the Changsari, Assam team plans the job.
Removal
Packs are dropped on a vehicle lift using the OEM procedure and a rated battery table, then isolated at the service disconnect.
Packaging
One pack per UN-rated pallet box, strapped and restrained, with terminals capped and coolant ports sealed.
Consolidation
Dealer and workshop returns are consolidated into full truckloads, typically eight or more packs per run.
Before the truck arrives
- Pull the service disconnect and record pack voltage
- Drain or cap coolant lines before lifting
- Photograph the pack casing and any impact damage
- Keep the VIN and pack serial together on the manifest
Changsari, Assam site notes
- Onward transit takes longer than elsewhere because of distance and terrain.
- Batteries are held in monitored storage until a full load is assembled.
- Keep batteries protected from rain and humidity before collection.
- Declare any damage in advance so isolated storage is available.
