【Note】: Before Connect The Balance Cable To The Balance Board, Be Sure To Check Whether The Connections Of Each Section Of The Battery Pack Are Correct, And Do A Good Job Of Insulating The Bottom Of The Board And The Battery String Connection Terminals. Default Setting Fit For Ncm/Lfp Battery, If You Use For Lto Battery, Please Remove The Previous Short Circuiting Pad And Then Re Short Circuiting The Lto Pad (With A Rectangular Short Circuiting Mark On The Board)..

Features

  • USE Tips The voltage gap of each battery must be within 0.5V. When the battery voltage difference does not reach more than 0.1V, the light on the balance board is triggered by mistake. The light actually has no balance current when it lights up, and it will automatically go out after a period of time. So We suggest re-plugging the cable to solve the problem. Note that It takes time to equalize the voltage, hot is normal and it does not take effect immediately after plugging it in.
  • NOTE : Before connect the balance cable to the balance board, be sure to check whether the connections of each section of the battery pack are correct, and do a good job of insulating the bottom of the board and the battery string connection terminals. DEFAULT setting fit for NCM/LFP battery, If you use for LTO battery, Please remove the previous short circuiting pad and then re short circuiting the LTO pad (with a rectangular short circuiting mark on the board).
