RANMEI BMS 2S 7.4V 8.4V 10A Lithium Battery Charge Protection Board Balancer Equalizer

Features: This protection board is for Lithium Polymer and Lithium Ion batteries only it cannot be used for Lithium Iron Phosphate batteries. Please ensure that the batteries are identical preferably from the same batch and have the same state of charge capacity and internal resistance. This module balances both charging and discharging the batteries. When the batteries are first connected if there is no output a charging voltage needs to be briefly applied to wake the board from sleep mode.
