36V Li-ion (10S) Battery Voltage Chart: Full (100%) to Empty (0%) Resting & Load Table
RÉSUMÉ TECHNIQUE & RÉPONSE DIRECTE • 36V LI-ION (10S) TELEMETRY
A fully charged 36V Li-ion (10S) battery measures 42.0V at 100% (4.20V/cell). Its 80% longevity charge target is 39.7V, its 50% winter storage midpoint is 37.5V, and its 0% BMS low-voltage cutoff is 30.0V (3.00V/cell). Under motor load, expect a dynamic voltage sag of ~2.4V.

Engineering Notes for 36V Li-ion (10S) Systems
Applications: Commuter E-Scooters (Xiaomi M365/Pro 2, Ninebot G30/G2) & City E-Bikes (Bosch 400/500Wh, Shimano Steps).
Charger Specification: Only use a dedicated 42.0V CC/CV (2A–4A) charger. Never connect a higher-voltage charger, and never charge a pack when internal cell temperature is below 0°C (32°F).
Winter Storage Window (40%–60%): Maintain resting voltage between 37.5V and 38.6V inside an insulated or fire-resistant enclosure.
