Tips: With LED equalization overvoltage indicator light, in order to avoid damage to the equalization plate, please discharge the voltage of each ultracapacitor to 0V before assembly, and then separately weld it on the ultracapacitor plate. Maximum charging voltage (V): Single rated voltage * N (N represents the number of series connections) Maximum charging current (A): (this current is related to the supercapacitor cell discharge current) Maximum discharge current (A): (this current is related to the supercapacitor cell discharge current) Minimum discharge voltage (V): 0.1 Single balanced starting voltage (V): Balanced starting voltage error: ±0.25% Single unit balance start display: red LED lights up Single balancing current (A): ≤1 DC internal resistance (mΩ): 1 Working temperature range (℃): -40~85°C Storage temperature range (℃): -40~85°C typical application: 3000F stud supercapacitor cell Depending on the batch, the color of the product details may be different, which does not affect use. Colour:Black Material:PCB Package Contents: 1 x Super capacitor protection board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
