BMS LFP 2S 4A (TDT) (72df)

Product Details

The 2S 4A LFP BMS Same Port Hardware Module is a Battery Management System (BMS) designed for 2-series (2S) Lithium Iron Phosphate (LFP) battery packs. It supports a continuous discharge current of 4A, making it ideal for low-power applications such as small IoT devices, LED lighting systems, handheld electronics, and backup power solutions. With a same-port configuration, this module allows both charging and discharging through a single connection, simplifying wiring and reducing system complexity. The BMS integrates multiple protection features to enhance battery safety and performance, including overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, and over-temperature protection. Overcharge protection prevents excessive voltage buildup, ensuring the battery remains within safe limits, while over-discharge protection safeguards against deep discharge that could shorten battery life. The overcurrent and short-circuit protections help prevent damage to the battery and connected devices by automatically cutting off power in case of excessive current flow. Additionally, thermal protection prevents overheating, ensuring stable and reliable performance under various conditions. Features:- Overcharge Protection  Over-Discharge Protection Overcurrent Protection Short-Circuit Protection Over-Temperature Protection Technical Specifications:- input Voltage B+ to B-: -0.3~+24V Overcharge Detection voltage/1CELL: 4.25±0.05V Over discharge Detection voltage/1CELL: 2.7±0.1V suggest working temperature: -20°C~+60°C Over current 17~23A The PCM LFP 02S/4A (TDT) is a Battery Protection Circuit Module (PCM) designed for 2 series lithium iron phosphate (LiFePO4) cells. It supports a 4A continuous discharge current, making it suitable for moderate power applications, including small energy storage systems, low-power electric vehicles, and backup power solutions that require a balanced level of protection and power handling. This PCM provides essential protection features, including overcharge, over-discharge, overcurrent, and short circuit safeguards, ensuring the battery remains safe during charging and discharging cycles. It also prevents potential damage to the battery by maintaining safe voltage levels. The TDT designation indicates a specific design or manufacturer, and the PCM is typically used in small 2-series LiFePO4 battery packs for a range of low to mid-power applications.
