Product Description
LT-13S054 | ISO13849 Certified 48V 25A BMS with Dual ICs
10S‑13S Li‑ion/LiFePO₄ | Separated Ports | NTC Sensor | Compact 50×40mm
The LT-13S054 Battery Management System (BMS) is a high‑reliability, ISO13849 certified solution designed for 10S to 13S lithium‑ion and LiFePO₄ battery packs (36V–48V). Featuring dual ICs for redundant protection, a 25A continuous discharge rating, separated ports for charging and discharging, and an integrated NTC thermal sensor, this BMS delivers exceptional safety and performance. Its compact 50×40mm size makes it ideal for electric bicycles, e‑scooters, light electric vehicles, and safety‑critical applications requiring ISO13849 certification.
📡 ISO13849 Certification
The LT-13S054 BMS is ISO13849 certified, indicating it has passed rigorous functional safety standards for machinery and control systems. This makes it suitable for applications where safety integrity is paramount, including electric vehicles, industrial equipment, and medical devices. Dual IC architecture further enhances reliability by providing two independent layers of protection.
⚙️ Key Features
🔒 Dual ICs for Redundant Protection
Two independent protection ICs ensure failsafe operation. If one IC fails, the second continues to protect against over‑charge, over‑discharge, over‑current, and short circuits.
⚡ 25A Continuous Discharge
25A continuous current capability supports high‑power e‑bike motors (up to 1000W) and demanding applications, ensuring consistent power delivery.
🔌 Separated Charge & Discharge Ports
Independent ports for charging and discharging simplify wiring and allow independent current rating optimization, enhancing safety and flexibility.
🌡️ NTC Over‑Temperature Protection
Integrated NTC thermistor monitors battery temperature in real time, preventing overheating and extending pack life.
🔋 Wide Battery Compatibility
Supports 10S–13S Li‑ion, Li‑Polymer, and LiFePO₄ cells, making it versatile for various 36V and 48V battery packs.
🚫 Anti‑Charging Reverse Connection
Protects the BMS and battery from damage due to incorrect charger polarity, enhancing user safety.
⚙️ Charging Turns Off Discharging
Intelligent logic automatically disables discharging during charging, preventing unsafe simultaneous operation.
📦 Compact Size
Dimensions: 50 × 40 mm – fits easily into e‑bike battery enclosures and space‑constrained compartments.
