Product Description
LT-P10S050 | UL2271 & ISO13849 Certified 36V 12A BMS for Electric Bicycles
Compact 40×50×1.5mm | NTC Thermal Sensors | Switch Functionality | Dual ICs + MOSFET
The LT-P10S050 is a high‑reliability, UL2271 and ISO13849 certified Battery Management System (BMS) specifically designed for 36V lithium‑ion battery packs used in electric bicycles, e‑scooters, pedelecs, and tube batteries. With an ultra‑compact size of 40×50×1.5mm, it seamlessly fits into downtube enclosures. Offering 12A continuous discharge current, perfect for 36V 250W–350W e‑bike systems, this BMS features dual ICs and MOSFET design, NTC thermal sensors, a convenient power switch, and full compliance with the highest safety standards — UL2271 (electrical systems for micro‑mobility) and ISO13849 (functional safety).
✅ UL2271 & ISO13849 Certification
The LT-P10S050 BMS meets UL2271 (certification for lithium battery packs in light electric vehicles) and ISO13849 (functional safety for machinery). These certifications guarantee that the BMS has undergone rigorous testing for electrical safety, thermal management, and reliable protection logic, making it an ideal choice for e‑bike and e‑scooter manufacturers requiring compliance with global safety regulations.
