How it works

192 AESC pouch cells, 96s2p, LBC inside a passively cooled case. Any scheduled discharge is the car plus an external CHAdeMO unit, not the pack alone.

Notes

Car hacking wiki: usable 39 kWh, 96s2p, AESC 56.3 Ah cell, 303 kg. Wikipedia: can send power back to the grid via CHAdeMO. PG&E 2026 lists LEAF 2018-2025 with a dcbel Ara, a utility programme not a built-in day-night mode. Pack voltage, pack Ah and outer dimensions not confirmed from a Nissan manual. 2024 US booklet: 96 months or 100000 miles, capacity remedy only below nine segments, pack returned to the vehicle. Used bulk price not confirmed.

Red flag

Passive cooling. Some 2019-2022 Smyrna cars with the quick-charge port are in NHTSA 24V700 and 25V655. Not every 40 kWh car. Warranty excludes opening the pack.
