Made my own adapter
Somewhat humorous post, also just to give inspiration to anyone else struggling to find an adapter for their particular batteries
Decided I was tired of shoving wires into a battery and hoping for the best, and had been thinking for a long time about taking apart a battery charger and turning it into an adapter, so I finaly did it! Tools used were cordless/handheld cut-off tool (like a tiny circular saw, a drenel would also probebly work) screw driver, soldering iron, overconfidence.
Used the cut-off tool to turn the star head screws on the charging piece into flat head screws, and also to cut a new slot for the metal into the negative spot since the charge normally went into the upside down T slot) tried to soldering the wires into place... theyre not moving atleast even if its a mess xD accidently got some soldering in the drill hole on one side, hence its slight melting when I tried to get the solder out of it. I'm not good at soldering and my iron is cheap, anyways, superglue the cords in to help!
Now I can swap the batteries out if/when I need to and dont have to undo my hard work and waste duct tape everytime they need to charge :D
