I’m trying to find this pcb but typing in the letters and numbers on the top or doing a reverse google search doesn’t bring up anything so I’d thought I’d try my luck hear. Its used for a small lamp I have and has a battery attached to it making it portable, I’ve found a battery similar to it I just need this and a way to make a remote controller work with it since I’m making something and don’t want to scrap my light just for these parts

Any help would be thankful
