It will push constant current into battery until battery voltage rises high enough so the supply can''t output constant current any more. But at this point the voltage will be the max output voltage, e.g. 12V, which will be way too much for a 1S or 2S pack. And the constant current is huge, much more than what typical cells accept. And the power
