The battery is a new type of energy storage product, which can be used to provide reliable power supply for various equipment and systems. It is especially suitable for applications with large power, limited installation space, limited bearing capacity and long life.Battery built-in bms battery management system, battery voltage, current, temperature and other information management and monitoring. In addition, the battery pack can balance the charge and discharge of the battery to prolong the cycle life. Multiple battery packs can be parallel to expand capacity and power, parallel to expand capacity and longer power support time requirements. 1.Environmental protection and pollution-free: the whole module using materials are non-toxic, pollution-free; 2.long safety life: the core cathode material of battery module is made of LiFeOP4, good safety performance and long service life; 3.Protection function: battery management system can protect battery module over discharge, over charge, over current and high / low temperature; 4.Equilibrium function: the battery management system has its own passive equalization, can balance the battery module each single string core; 5.Expansion: flexible configuration, multiple battery modules can be parallel expansion capacity, applicable to different standby time requirements; 6.Low power consumption: the battery has the function of automatic dormancy, when no live equipment is connected, it can enter the low power state by itself and reduce the self-loss; 7.No memory: no memory effect, shallow charge and discharge performance is excellent; 8.Wide temperature range: working temperature range-20~70, charge 0~60, discharge-20~70, good discharge performance and cycle life, Built in BMS overall protection 1.Over charged protection 2.Over discharged protection 3.Thermal protection 4.Over current protection 5.Cell balancing
