Regarding the control of current from a SMPS into a very low impedance battery…I believe the following “type” of feedback loop will be able to do it…the ringed RC network prevents the current from "running away".
As we know, a voltage regulation loop controlling a battery voltage (ie, a large capacitive output) is more difficult, but a current regulated loop into a low impedance load (eg big capacitor) is not so difficult.
