How to Connecting a BMS Quick Guide2 weeks, 5 days ago | 0 Replies
Just want to share how I connected BMS to LiPos. In this case I will use two 4S Lipos in series with an 8S BMS… But this guild should work with any LiPo configuration you want to use.
You will need: BMS LiPo battery welding skills.so I didn’t think about making this tutorial until I had welded all the components together… I’ll update it when I do this again, but until then hopefully the images are helpful.
This diagram shows how the BMS should be wired.
You will need to weld the negative leads to positions B and P. And the last black line on the balance lead from the battery needs to be welded to position B.
For series connections, it is important to follow this diagram so that there is no short circuit when connecting the battery.
You can see THAT I have all five balance leads on the battery, the positive ones, but I only have the last four with the negative ones (the red ones removed). The last black wire connects to position B-.
Make sure to plan how you will actually connect everything before you connect it, you only have one chance, if any of your parts are short, they won’t work again and just lose your money.
Once you check everything out. You must first insert the negative wire into the B- position.
After you can continue to connect the balance wires to the battery, then connect them all to the BMS.
When done, the positive leads come from the battery and the negative leads come from the BMS. This will allow you to charge and discharge to keep the battery balanced.
To charge, you need to get a compatible charger (voltage varies with your LiPo configuration) and DC plug for soldering… I welded all the connections to the switch. The Switch has an LCD on one side and a charger lead on the other.
The charger should indicate when the battery is charged or fully charged. (Red = charging, green = full)
In the end, your build should look something like this, and all that’s left is to fix the electronics and organize them on the board to your liking!
I hope I can help you and feel free to ask any questions.Check out some of the components used in this release at MiamiElectricBoards.com.
