TopHomer LiFePO4 BMS Battery Protection Board 4S 250A 12V Lithium-Ion Battery Protection Module w/Balance Overcharge/Over Discharge/Overcurrent protection

Multiple Protection: BMS has the functions of overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, voltage equalization, etc., to protect your battery in an all-round way

High Quality: The battery protection board adopts a high-quality metal shell to protect the internal electronic components, which can prevent the battery pack from exploding, fire and damage, and ensure the performance of the lithium battery protection board

Heat Dissipation: The thickness of the lithium battery protection plate is 20mm/0.78in, and it is equipped with a heat dissipation aluminum plate, which reserves enough space for heat dissipation to achieve rapid heat dissipation and avoid damage to the protection board battery due to high temperature accumulation inside the protection board

Same Interface: The lithium battery protection board adopts the same interface design, only two wires are needed for charging and discharging, and the battery protection board also has a equalization function, which can maintain the balance and good service life of each battery

Size & Application: The overall dimensions are 23 x 10.5 x 2 cm, the operating temperature is -20-70°C / -4-158°F, the continuous current is 250A, and the peak current is 500A, mainly used for 4S 12V lithium iron phosphate batteries
