Product Description
LT-P13S017 | Gourd‑Shaped 13S 48V Tube Battery BMS for e‑Bikes
Separate Charge/Discharge Ports | NTC Sensor | E‑Switch | 7S‑14S Support
The LT-P13S017 Battery Management System (BMS) is a uniquely designed, gourd‑shaped BMS specifically engineered for electric bicycles with tube (downtube) batteries. Its innovative shape fits seamlessly into cylindrical battery enclosures while providing powerful battery management for 13S 48V lithium‑ion packs (compatible with 7S‑14S configurations). Featuring separate ports for charging and discharging, an NTC thermal sensor, an E‑switch, and comprehensive protections (over‑charge, over‑discharge, over‑current, over‑temperature, short circuit), this BMS ensures optimal performance, safety, and ease of use for 250W–500W e‑bike systems.
📡 Key Features
🍐 Unique Gourd‑Shaped Design
Optimized for tube‑style e‑bike battery enclosures. Fits perfectly into downtube housings while maintaining a clean, aesthetic appearance.
🔌 Separate Charge & Discharge Ports
Dedicated ports for charging and discharging simplify wiring and allow independent management, enhancing safety and usability.
🔋 Wide Voltage Compatibility
Supports 7S to 14S lithium‑ion battery configurations (24V–52V), with a primary focus on 13S 48V packs for e‑bikes.
🌡️ NTC Thermal Sensor
Accurate temperature monitoring prevents overheating, ensuring safe operation and extending battery lifespan.
🔘 E‑Switch for Easy Control
Integrated E‑switch allows convenient power on/off control, simplifying battery management for riders.
🛡️ Comprehensive Protections
Over‑charge, over‑discharge, over‑current, over‑temperature, and short circuit protections ensure maximum safety and reliability.
