Comprehensive protection features including overcharge, over-discharge, and short circuit protection to ensure battery safety and longevity. Supports high-current applications with a maximum operating current of 100A and an instantaneous current of 120A. Temperature protection feature can be enhanced by adding a normally closed temperature sensor switch for improved safety. Compact dimensions of 70*60*8.5mm make it suitable for various battery pack configurations. Delayed self-recovery short circuit protection ensures reliable operation after fault conditions. The HX-3S-F100A lithium battery protection board is engineered to provide essential safety measures for battery packs. It features a maximum charging current of 10A and operates within a charging voltage of 12.6V. The overcharge voltage range is set at 4.28V ± 40mV, while the overdischarge voltage range is 2.5V + 80mV. Additionally, it includes an equalization current of 56mA to maintain battery health.
