The anwer is "No".Each battery pack will have a BMS to manage this battery pack. They will have an internal electronic management system. If the battery packs connected in series, the high voltage will damage the components to of the BMS and destroyed the BMS. So that the BMS can not protect the battery again. If connect the battery packs in parrallel, it will not cause so serious problem. But the...

The anwer is "No".One battery pack will need one BMS. Forexample the 36V Li ion battery pack, there should be 10 data wires connected to each cell. These data wires are used to examine the data from the cells so that the BMS can manage the battery pack. That it is impossible to connect several packs to only one single BMS.

1. Our standard chargers are 2A for 12V, 24V, 36V, and 48V bateery packs. Below is the simple description for your reference:the output is 2A only;with plastic case;the AC wire is fixed to the case and can not be disassembled;with cooling fan;90-120VAC or 200-264VAC option;2. The Smart chargers output curent is adjustable as customers' requirements:with Aluminium shell and easier for cooling;with ...

1. All of our simple battery packs are included Lithium Ion cells, BMS, discharging connector, charging connector, extra discharging connector for your controller;2. All of our battery packs in cases are included Lithium Ion cells, BMS, battery case, case supporter for amounting to your bikes, extra discharging connector for your controller;

I. Active BMS is with Max 2A balancing current. If using balancing module, it can do Max 5A balancing current. This will make the balancing quickly. Passive BMS is only 80mA balancing current Max.II. The Active BMS will not cause high temperature. But the Passive BMS will do. When discharging current meet 100A continuous discharging current, we will not supply Passive BMS but only Active BMS.Summa...

1. We will collect the accordant cells befor assemble the battery. the accordance is very important for a battery pack. We think the best way is to avoid any problem before sending out the battery packs;2. After the assembling, we will test the completed battery pack for 2-3 cycles to make sure the cells are still accordance after assembling. and make sure the capacity and voltage is correct. This...
