Applicable battery type:Ternary lithium or lithium iron phosphate or lithium titanate 6-8SWorking voltage range: ternary lithium or lithium iron phosphate: 2.7-4.2V Lithium titanate: 1.8-3.0VEqualization voltage accuracy: 5mV (standard)Balance mode: active balancing of the entire battery group participating in energy conversion simultaneouslyEquilibrium 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 3AUndervoltage protection sleep voltage: ternary lithium or lithium iron phosphate: 2.7V lithium titanate: 1.8VWorking environment temperature -10 -60 External power does not require an external power source, relying on the energy transfer inside the battery to achieve the balance of the entire battery packColour:As ShownMaterial:plasticstyle: with ShellPackage Contents:1 x 8S 3A BalancerOnly 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.
