Features: 1. Up to 1.5A equalizing current, efficient equalizing, low consumption, stable, and reliable circuit structure eliminates the risk of similar faults (the equalizing current varies with the voltage difference between batteries) 2. Select low resistance and high frequency ceramic capacitors, and select high-quality components to promote performance and reliability. (The appearance, packaging and parameters of capacitors with different batches) 3. Low heat, high reliability and high , suitable for internal battery pack operation or external battery maintenance equalization, with equalization accuracy of 3mV 4. The active equalization module of capacitive lithium battery is used for voltage equalization between lithium battery packs, and the operation between the module and the protection board does not affect each other. It is applicable to pack, repair and DIY battery pack. Parameters: Product specification: 4S Equalizing current: 1.5A maximum (different from differential pressure, internal resistance, line resistance, etc.) Equalization accuracy: 3mV Suitable for batteries: lithium iron phosphate and lithium ternary Material: Electronic components colour: As shown Package Contents: 1 x module circuit body 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.
