Notes

Classic Hyundai Ioniq 28 kWh battery revered in the EV community for its extremely low degradation and active air cooling. 96s series LG Chem pouch cells with 270.0–405.0 V* operating range. Supported natively by Battery-Emulator HYUNDAI-IONIQ-28-BATTERY driver.

Red flag

Forced air fan cooling must have unobstructed intake and exhaust; excellent cell chemistry with virtually zero dendrite issues.
