Rechargeable 12V 7800mAh 3S3P 18650 Lithium-Ion Battery Pack for Traffic Signal Lights

The 12V 7800mAh 3S3P 18650 lithium-ion battery pack is designed to be used in traffic signal lights and other outdoor control systems that need consistent power, small size, and reliable cycling capabilities. The pack consists of a 3-series, 3-parallel configuration of 9 18650 cells that provide a reliable source of energy to operate continuously or on backup. A built-in BMS offers overcharge, over-discharge, overcurrent, short-circuit, and abnormal temperature protection and assists in enhancing safety and service life. The battery is customizable in size, casing, connector type, cable length, charging current, discharge current, and installation. Its lightweight and high energy density properties make it applicable in portable traffic lights, temporary road signs, solar-powered warning lights, construction zone devices, emergency traffic systems, and intelligent transportation devices. Customers who need special electrical parameters, enclosures, communication functions, or environmental protection (outdoor use) are supported with OEM and ODM.
