Where do you connect BMS?
Connections to the BMS
- The negative of the battery pack goes to the B-
- The positive of the battery pack goes to the positive of the charger, and to whatever we want to power (in out case an amplifier for our portable speaker)
- Solder a wire to P-. This will be the negative terminal.
- Some BMS’s have C- point.
What are the load terminals for on a charge controller?
Some controllers also have a “LOAD”, or LVD output, which can be used for smaller loads, such as small appliances and lights. The advantage is that the load terminals have a low voltage disconnect, so it will turn off whatever is connected to the load terminals and keep from running the battery down too far.
What is the load on a charge controller?
The load terminals on a charge controller power connected DC devices. The DC device must be compatible with the battery nominal voltage, and the battery bank capacity should be appropriately sized for the load. Loads can be many things from a DC refrigerator to a DC LED light.
What kind of Charger do I need for my BMS?
Common connectors for charging are XT-60, Anderson Power Poles, XLR and DC 2.5 mm barrel connectors, but anything that can carry the load will work. At this point your BMS is completely connected, but you’re not quite done yet. Your positive charge and discharge wires usually won’t connect to the BMS.
Where does the BMS connect to the battery?
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.

Where do the balance wires start on a BMS?
But if you have a BMS with the same number of balance wires as series cells, you’ll start on the positive end of the first cell group, which is the opposite side of the first cell group from where the thick B- wire was connected.
