20-84V 40-100V DUAL BATTERY DISCHARGING MODULE ADAPTER 30A 40A 80A 100A 120A 150A The Dual batteries connected in parallel for additional capacity and range, and the switcher can manage the two batteries on your bike. Auto Battery on-line detecting. If only one battery is connected with module, will switch to this battery automatically. This module can make both batteries discharge together to power the ebike, the BMS inside will compare the voltage of each battery in real time and adjust the current output for each battery automatically. When two batteries are used at the same time, the batteries with higher voltage will be discharged first, and when the two batteries have the same voltage, they will start to discharge at the same time until they are exhausted. Note: 1. Do not confuse the positive and negative connectors on the dual battery switch. Make sure that the power of both batteries is turned off before connecting.2. The voltage of the two batteries should not be too different. 3. Suitable for maximum 30A / maximum 40A / maximum 80A / maximum 100A / maximum 120A / max 150A controller（Optional） Water resistantApplicable voltage：20V～84V(30A 40A)/ 40~100V(80A 100A 120A) Compact Size, Weight, Wire diameter and Plug 30A version: 45x18.5x60mm, 110g, 14AWG, XT60 Male and female 40A version: 45x18.5x72mm, 120g, 14AWG, XT60 Male and female80A version: 63x25x78mm, 390g, 11AWG, XT90 Male and female100A version: 63x25x78mm, 350g, 10AWG, QS8 Male and female120A version: 63x25x78mm, 400g, 10AWG, QS8 Male and female150A version: 63x25x78mm, 410g, 10AWG, QS8 Male and female Working Process 1) MCU monitor voltage of both batteries in real time and send voltage data by UART port (if UART interface is available); 2) Auto Battery on-line detecting. If only one battery is connected with module, will switch to this battery automatically; 3) If the voltage of both batteries are not same, the module will discharge the battery with higher voltage firstly till two batteries voltage approaching similar, then will discharge both batteries together at same current (Iout=Ia+Ib, Ia=Ib); 4) When the voltage of both batteries are same, the module will discharge both batteries together, Iout=Ia+Ib Warranty:We have one year warranty for all quality problem (not include normal wear out parts), within warranty period, we can supply free exchange and repair service. After warranty period, we still can supply exchange or repair service under charge. Return Policy:We do our best to serve our customers.
