# Connecting BMS to charge controller and load

Im trying to design a circuit that the load will get power from solar panel or a battery (in case the solar panel will not deliver enough current\voltage)

Also wanted to mention that this is a hobby, so I dont have deep knowledge in electronics..

So the question is about connecting charge controller and BMS-2S to load

1. 12v solar panel connected to charge controller as input
2. 2S (3.7 each) Li-Ion batteries


about the BMS, it says that pins P+ connected to charger+ and load+. And P- connected to charge- and load-.

Connecting that way, that the BMS and the load are parallel to charge controller, will not interrupt the charge controller main goal? Im wandering how it will affect the Constant Current and Constant Voltage mechanism.

Im not sure that the load supposed to be connected that way, ill be happy for guidance.

Thanks

• Did you find your answer? I'm also wondering if load and BMS in parallel impacts charging. – rrmoelker Mar 14 at 19:12
