How to control current to charge batteries?
I have a DC boost that converts the 2.5V/4.2V of my battery pack to constant 5V output (and can output up to 3A, which is nice). Here is my problem : my BMS does not limit INPUT current. I choosed this BMS specifically because it has big OUTPUT current (about 15A). The datasheet of my 18650 cell says I can charge it at 1.7A max.
