  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.
