Li-ion pack regulator


#1

I am building a 4S9P battery pack with 18650 li-ion cells, the voltage varies from 10.2V to 16.4V depending on the charge and I am looking at a regulator that delivers around 12V 5A minimum at any stage of the charge. I also have size constraints, your design look excellent but I could not find a step-up / down converter that could match my requirements, specially above 5A

Thanks

Hello.

Unfortunately, as you noticed, we do not have a step-up/step-down regulator that can handle 5A while outputting 12V, and we do not have any recommendations on where you might find one. Since you are making your own battery pack, you might consider increasing the nominal number of cells and using something like our 12V 15A step-down voltage regulator.
