432 LG pouch cells in 36 modules wired as 108s4p. Jaguar Battery Energy Control Module (BECM) monitors cell voltages, temperatures, and contactors. Battery-Emulator transmits wake frames and receives full telemetry over high-speed powertrain CAN.
Pack consists of 432 LG pouch cells arranged in 36 modules (each 12 cells in 3s4p), wired in series to create a 108s4p string. Operating voltage window 337.0–454.6 V*. Battery-Emulator provides native Jaguar BECM emulation over 500 kbps CAN bus. Highly popular for high-capacity home storage due to 84.7 kWh usable capacity in a single sealed pack.
LG pouch cells in early 2019–2020 models subject to thermal overload safety recalls (H441/H459/H471); heavy sealed assembly (613 kg) requires engine crane or pallet lifter; BECM requires continuous CAN heartbeat to prevent contactor dropout.
