Can You Put Bms In Parallel?
The short answer is yes, you can put BMS units in parallel. However, there are a few things to keep in mind if you decide to do this. First, if one of the BMS units goes into protect mode, the other unit will likely go into over current protect mode fairly soon after. This is because the BMS units are designed to work together and when one unit goes into protect mode, the other unit will follow suit. Second, be sure to check the calibration on both units and set them to the exact same shut off points. This will ensure that both units are working together properly. Finally, there are some benefits to building the system as 2 or 3, or even 4 separate batteries. This will allow each battery to be used independently if needed and will also provide a higher level of protection should one of the batteries fail.
