Just want to share how I connected my BMS to LiPos. In this case I will be using two 4S Lipos in series to an 8S BMS… However this guild should work out for any LiPo config you would like to use.
You will need: BMS LiPo Batteries Soldering Skills
So I did not think about making this guide until I had already soldered all my components… I will update when I do this again but until then hope the pictures help.
This picture shows how the BMS is supposed to be wired.
You will need to solder the negative leads the the B- and P- locations. As well as the last black wire on the balance leads from the battery will need to be soldered to the B- Location.
For wiring in series, it is very important you follow this chart so nothing gets shorted when connecting your batteries.
You can see I have all five balance leads on the battery with the positive wire but i only have the last 4 on the battery with the negative wire(red wire removed). With the last black wire going to the B- location.
Make sure you plan how you are going to connect everything before actually connecting it as you will only have one chance, if you short any of your components they will not work again and just lost your money.
Once you have double checked everything. YOU MUST FIRST plug in the negative wire to the B- location.
After you can go ahead and connect your balance lead to your battery and then connect them all together to the BMS.
When you are done you will have your positive lead coming from the battery and your negative lead coming from the BMS. This will allow you to charge and discharge keeping your battery balanced.
To charge you will need to get a compatible charger(Voltage varies on your LiPo config) and DC-plug to solder… I Soldered all my connections on the a Switch. One side of the Switch has an LCD and the other side had the charger leads.
After your charger should indicate when your battery is chargeing or full. (Red=Charging, Green=Full)
In the End your build should look similar to this, all that is left is securing the electronics and organizing them on the board to your taste!
Hope this helps, feel free to ask any questions.
