Product Description
LT-10S081 | Ultra‑Narrow 10S 36V BMS
17A Continuous Discharge | Dual NTC Sensors | E‑Switch | Fits 2×18650 Cell Thickness
The LT-10S081 Battery Management System (BMS) is a compact, high‑performance solution designed for 10S 36V lithium‑ion battery packs, commonly used in electric bicycles, e‑scooters, and light electric vehicles. With an ultra‑narrow size of 34.5 × 89.5 mm (just 2×18650 cells in thickness), it fits easily into space‑constrained battery enclosures. Featuring common ports for charging and discharging, dual NTC thermal sensors, an E‑switch, and 17A continuous discharge capability, this BMS delivers reliable protection, precise control, and easy integration.
📡 Key Features
📏 Ultra‑Narrow Size
Dimensions: 34.5 × 89.5 mm – only the thickness of two 18650 cells. Perfect for downtube and rear‑rack e‑bike battery packs where space is at a premium.
⚡ 17A Continuous Discharge
17A continuous discharge capability provides ample power for 250W–500W e‑bike motors, ensuring smooth acceleration and reliable performance.
🌡️ Dual NTC Thermal Sensors
Two independent NTC thermistors monitor battery cell and MOSFET temperatures, preventing overheating and extending battery life.
🔘 E‑Switch for Easy Control
Integrated E‑switch allows convenient power on/off control, simplifying battery management and improving user experience.
🔌 Common Ports
Same port for charging and discharging reduces wiring complexity, making installation cleaner and more reliable.
🛡️ Discharge Turn‑Off While Charging
Intelligent design prevents discharge during charging, safeguarding the battery and optimizing charging efficiency.
🛡️ Comprehensive Protections
Over‑charge, over‑discharge, over‑current, short circuit, and over‑temperature protections ensure maximum safety and longevity for your battery pack.
