Applicable battery type:Ternary lithium/lithium iron phosphate/lithium titanate 6-8S Working voltage range: ternary lithium/lithium iron phosphate: 2.7-4.2V Lithium titanate: 1.8-3.0V Equalization voltage accuracy: 5mV (standard) Balance mode: active balancing of the entire battery group participating in energy conversion simultaneously Equilibrium current: When the voltage difference is 0.1V, the equilibrium current is 0.3A. The greater the voltage difference, the greater the equilibrium current. The maximum balanced current is 3A Undervoltage protection sleep voltage: ternary lithium/lithium iron phosphate: 2.7V lithium titanate: 1.8V Working environment temperature -10 ℃ -60 ℃ External power does not require an external power source, relying on the energy fer inside the battery to achieve the balance of the entire battery pack Colour:As Shown Material:plastic style:Without Shell / with Shell Package Contents: 1 * 8S 3A Balancer 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.
