Specification: Brand BIKIGHT Product 20S 72V Lithium Battery Protection Board Size 126 x 67 x 9mm / 4.96 x 2.64 x 0.35inch Discharge Continue Discharge Current 45A Discharge Peak Current 180A Over Current Protection 180A Charge Voltage 84V Charge Current 45A Over Charge Detect Voltage 4.250.025 Over Charge Protection Delay 0.5S Over Charge Release Voltage 4.190.05 Balance Detection Voltage 4.18V Balance Release Voltage 4.18V Balance Current 355mA Over Discharge Detect Voltage 2.80.05V Over Discharge Detect Delay 0.5S Over Discharge Release Voltage 3.00.05V Over Current Detect Voltage 150mV Over Current Detect Delay 9MS Over Current Protection Release Condition Off load Short Circuit Protection Condition short circuit with extermal load Short Circuit Detection Delay 250uS Short Circuit Protection Release Condition Off load Temp Protection 65/75 Main Circuit Conductive Inner Resistance 10m Working Current 40uA Sleeping Current (Battery in Over Discharge) 20uA Working Temp Range -30 to 80 Features: Use top quality (A-level) protective integrated circuit IC from Japan. Strong load ability. Constant discharge current 45A. Use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling. IC itself has power balancing function. The circuit is simple and reliable. Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable. Long time short circuit of the load won't affect the PCB and the battery. Temperature protection during charging and discharging. Extreme low power consumption. The consumption of the whole device is less than 40uA. PCB coated with high anti-corrosion, high water resistance, high impedance ESD. The temperature drift is extremely low, and the accuracy is 1% high power package sense resistor. It adopts sealing and waterproofing technology. Dustproof, shockproof, anti-extrusion. Its service life is twice that of ordinary protective plates. Package Included: 1 x BIKIGHT 20S Li-ion Battery Board
