52V Li-ion (14S) Battery Voltage Chart: Full (100%) to Empty (0%) Resting & Load Table
ENGINEER SUMMARY & QUICK ANSWER • 52V LI-ION (14S) TELEMETRY
A fully charged 52V Li-ion (14S) battery measures 58.8V at 100% (4.20V/cell). Its 80% longevity charge target is 55.6V, its 50% winter storage midpoint is 52.5V, and its 0% BMS low-voltage cutoff is 42.0V (3.00V/cell). Under motor load, expect a dynamic voltage sag of ~3.5V.

Engineering Notes for 52V Li-ion (14S) Systems
Applications: High-Performance Bafang BBSHD 1000W Builds, Ariel Rider, Dual-Motor Scooters (Apollo Phantom, Kaabo Mantis).
Charger Specification: Only use a dedicated 58.8V CC/CV (3A–5A) 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 52.5V and 54.0V inside an insulated or fire-resistant enclosure.
