Features 【Short Circuit Protection】This lipo battery protection board is designed to protect the battery from short circuit accidents. In case of a short circuit, the balancing PCB board will immediately shut off the circuit to prevent any damage to the battery. 【Temperature Protection】The ternary lithium balancing PCB board also monitors the temperature of the battery. If the temperature rises above a certain level, it will stop the charging or discharging process to prevent any damage to the battery. 【Balancing Fuction】Featuring a built-in balancing function, the capacitor protection board ensures that all battery units are fully charged at the same time, making it ideal for use in electric vehicles, mopeds, scooters, and inverters. 【Versatile Application】This 2.7V 16V protection board is highly practical and can be used for a variety of lithium-ion battery types, including ternary lithium battery, ferrous lithium phosphat battery, lithium titanate battery, making it suitable for a wide range of electronic devices. 【Overcharge/Overdischarge protection】The Ouitble balancing PCB board is designed to prevent overcharging of the battery,also protects the battery from being discharged below its safe limit. It monitors the voltage of each cell and cuts off the charging when the voltage reaches its maximum or minimum level. 1. MAIN PURPOSE: This balance protection board is suitable for capacitors and lithium titanate batteries with a voltage of 2.7V, which is efficient and practical. 2. FINE TUNING RANGE: The protection voltage can be fine tuned within 2.5V‑3V by replacing the voltage divider resistor (higher balanced voltage requires high resistant power resistor). 3. WORKING PRINCIPLE: When the single battery or capacitor voltage higher than the balance voltage, the circuit opens the triode for discharge, excess electricity through the power resistant into heat dissipation out. 4. SIMPLE WIRING: The single protection board is suitable for any 1‑6S battery or capacitor. When it is less than 6S, connect it from the negative pole, and the excess wires can be left empty. 5. GOOD PERFORMANCE: The protection board is equipped with indicator light, clear and intuitive, the circuit balance voltage accuracy is ±1%, and equipped with connecting wire, easy to connect and use.
