Positive and Negative Terminals: The positive terminal of the first battery cell is connected to the negative terminal of the second cell, and so on, until the positive terminal of the fourth cell is connected to the negative terminal of the battery pack. Balance Wires: The BMS also requires connection to the balance wires of each battery cell.
Your positive charge and discharge wires usually won’t connect to the BMS. Instead, they usually connect directly to the battery. They will both connect to the positive end of your last cell group, which is the positive terminal of the entire battery.
The P- wire is the negative discharge connection, so that will plug into whatever device you are powering, such as an electric bicycle or skateboard controller, an inverter, etc. Our BMS already has this wire soldered to the BMS, so you are essentially done at this point, unless you want to lengthen that wire by soldering on a longer piece.
It receives data from the battery cells and sends commands to balance the charge if necessary. The Main Plus and Minus connections connect the battery pack to the load or charging source, allowing the flow of current. Lastly, the Balance wires connect each individual cell to the BMS module, enabling the monitoring and balancing functions.
Just like when you connected the B- wire, crimp the positive charge and discharge wires onto the wire clamps on your VRUZEND battery. For the discharge wire, you’ll want to use the same thickness wire you used for the B- and P- wires, usually 12 or 14 AWG. The charge wire can be thinner, from 14-18 AWG.
I have 4 18650 batteries and I want to make a battery pack of it. If all the batteries were new and had similar voltage/capacity I could easily charge them all together in parallel with my charger. However the batteries have about 10% difference in capacity so I need to charge them using a balance wire on each battery/cell.
They all come with XT60 discharge ports and XLR (three pin) charge ports on the battery. My recent purchase was a 60V 40AH (big boy) for a different bike. Same thing, …
