Featuring a robust 200A continuous current rating, built-in Bluetooth for real-time monitoring via mobile app, and active cell balancing technology, it ensures optimal battery safety, longevity, and efficiency. Ideal for solar energy systems, electric vehicles, and portable power solutions, it offers versatile compatibility and easy installation with comprehensive protection against electrical and thermal risks. ## Description Protection Board Selection FAQ A: For instance, with a 20S 60V 100A protection board, "same port" means your charging negative and discharging negative are connected at the same point (P-). They share a common interface, so both the charging current and discharging current are 100A. On the other hand, "different port" means the charging negative (C-) and discharging negative are separate (P-), connected at different points on the protection board. Thus, the charging and discharging currents can differ—discharging at 100A and charging at 100A. A: The size of the battery capacity does not directly correlate with the current of the board. Capacity is not about the physical size of the battery but rather the continuous current. It depends on your controller's current limiting—the higher the limit, the larger the continuous current rating needed for the protection board. It's not directly related to battery capacity. A: For lithium batteries, you must use a charger specifically designed for lithium batteries. Never use a lead-acid battery charger, as it could potentially exceed the protection board MOSFET's voltage tolerance, leading to overcharging without protection. For lithium iron phosphate batteries, charger voltage = number of series cells * 3.65V; for ternary lithium batteries, charger voltage = number of series cells * 4.25V. A: The current rating of the protection board depends on the current limit set by the controller, which in turn depends on the power of the motor. For example, if the motor is 64V, 1000W, then the current is 1000/64 = 15.6A. Therefore, the controller's current limit must be greater than 15.6A, and the protection board's current limit must be greater than the controller's limit. Always leave a margin during the selection process. ## Features - Enhanced Safety: Safeguard your battery with protection against overcharging, overdischarging, overcurrent, short circuits, and temperature extremes.
