The individual ENEPAQ 1s6p submodules that make up the pack.
Each submodule is 6 cells in parallel, arriving with fuses, temperature sensors, terminals and busbars installed. Connecting 105 in series reaches the target voltage and power output.
No part-specific design process is documented. The Energy Storage subsystem design process applies: 1. Run the lap simulation to get energy per lap and the required capacity, iterating on pack mass until it converges. 2. Derive initial pack parameters: nominal 420 V, nominal 130 A, 210 A peak for 120 s, preferred capacity 6.552 kWh, maximum 80 kW power draw as capped by EV.4.1.1. 3. Take vendor options against those parameters and select the closest cell. 4. Check each candidate against the rules: EV.8.4.1 cell voltage measurement, EV.6.2.3 nonflammable inter-segment insulation, EV.7.6.1 overcurrent protection, EV.8.5.3-5.7 temperature measurement location, coverage and isolation. 5. Hand the segment geometry to EV Structures so the container can be designed around it.

Five battery segments at 15 lb each in the CR26E accumulator. From the design reports and one-pagers: $85.03 per ENEPAQ 1s6p module. Delivered pre-assembled, which is the main practical argument for buying rather than building. From the cost report drawings and CAD: Weighed mass: 339.1 g (0.747 lb) (recorded as: Battery Module).
