The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential pressure when charging and discharging on the battery pack. Trigger equalization, the battery pack voltage error will be pulled back to the Perfect value, reducing battery maintenance costs.
Working voltage is 2.0V-4.5V, ternary iron lithium battery is common, lithium cobalt oxide battery is not applicable. Note:There will be some heat in the first use, no need to deliberately dissipate heat, just use it normally Material:metal colour: blue Package Contents: 1 Active Balance board Only the above package content, other products are not included.
