Specification: Brand BIKIGHT Product 13S 48V Lithium Battery Protection Board Size 73 x 61 x 9mm / 2.87 x 2.4 x 0.35inch Discharge Continue Discharge Current 25A Discharge Peak Current 60A Over Current Protection 60A Charge Voltage 54.6V Charge Current 25A Over Charge Detect Voltage 4.250.025V Over Charge Protection Delay 0.5S Over Charge Release Voltage 4.190.05V 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 NA 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. Strong load ability. Constant discharge current 25A. 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 13S Li-ion Battery Board
