12V to 48V lead acid can replace modular batteries.deep cycle trolling motor battery

　　Diaphragm

　　Isolation battery cells are positive and negative to prevent the roll core from positive positive and negative electrodes directly contact the short circuit; from a micro perspective, the surface of the diaphragm is a mesh structure, usually with PP and PE. Essence

　　Division of diaphragm is usually divided according to thickness and width. The thickness of the diaphragm used in aluminum -shell lithium -ion batteries is usually 16um, 18um, 20UM, etc. The thickness of the diaphragm used in power batteries is mainly based on 30um.

　　If the shape is distinguished, there are rolls and strips. Rolling the diaphragm is rolled on a paper tube with cutting width on a paper tube for customers to cut the single length of the diaphragm by themselves (the shape is similar to the transparent glue). The strip septum is directly cut into strip -shaped septum according to the length, width, and thick parameters provided by the supplier. The advantage of curling diaphragm is that the universality is strong, but it is necessary to increase manpower for tailoring. The advantages of strip -like diaphragm is that it can be used without human cutting, but the universality is not strong.

　　The diaphragm can be melted when the temperature inside the battery is too high to prevent the battery from exploding. When the internal temperature of the battery reaches 130 ° C (national standard GB18287-2000) or more, the mesh hole of the diaphragm will be closed to prevent lithium ions from rising internal resistance (to 2kΩ) to achieve preventing the internal temperature of the battery. High role, thereby protecting the risk of explosion of the cell.

　　Once the exhaust holes and septum are activated, the battery will be permanently invalidated.

　　Modular battery refers to the module with a set of batteries as a separate module. It can be connected between the outside or in the internal module and the module to increase the capacity or increase the voltage. Lithium -ion batteries, we do 12V to 48V lead acid can replace modular batteries, where we use lithium iron phosphate batteries to replace lead -acid batteries.

　　For example, NEC's 1: 1 lead-acid battery of 12V company is 12V 5AH, and the discharge multipliers 4C-9C support fast charging, large current discharge; built-in BMS: overcharge, overplay, high and low temperature protection, overcurrent protection, built-in built-in The balanced circuit; our lead -acid can replace the modular battery can reach the corresponding specifications parameters by module merging. At the same time, we have our own BMS products to replace the lead -acid battery well; our modular battery can support The 4 modules are connected to 48V; 10 modules are parallel to 50AH.

　　Since the modular battery can be stringed more, the application field of the product is wide. Common application areas are: communication power systems, such as base stations; UPS systems, such as industrial automation UPS, server UPS; power support in the environment of departure or weak network power system; security system, emergency lighting power supply; portable medical diagnosis Equipment, some products need fast charge, which is convenient for patients to provide the fastest and timely services.
