Product Description
LT-P04S003 | 4S 12V 100A LiFePO₄ BMS with NTC Thermal Sensor
100A Continuous / 400A Pulse | Supports Battery Series Connection for 24V/48V Packs
The LT-P04S003 is a high‑current Battery Management System (BMS) designed for 4S (12V) LiFePO₄ battery packs. With 100A continuous discharge and 400A pulse current capability, it delivers robust power for demanding applications. Equipped with an NTC thermal sensor for over‑temperature protection, this BMS also allows series connection of multiple identical battery packs – for example, connecting four 12V 100Ah packs to create a 48V 100Ah lithium battery system. Ideal for solar energy storage, RVs, marine systems, golf carts, backup power, and industrial equipment.
