Hi everyone.
Is there a way I can mod an original de-walt DE9119 ni-mh battery charger so that it can work with a 4s li-ion bms battery? I guess as is it will not work ( haven't tried it tho ), but basically I want to know if I can tap in and get DC 18-35V from it so that I can use one of those aliexpress dc-dc step-down converter boards with V and C control.
Here are are the schematics of the charger ( see attached ).
I do not know what type of PSU is this but does not look like any of the smps I've seen/fixed.
p.s. I'm adding the datasheet of the IC... which seems to be a microcontroller.. the damn thing starts to look too smart for my needs.
