Look for a mini "pot" (potentiometer, in other words a variable resistor), usually near the output wires. Turn it one way or the other with a small screwdriver. Look like this, though maybe only 1/4" or smaller across:
You might "cook" the charger like I did, mind you, as you can probably expect a lithium battery to suck down the amps faster than a cheap lead-acid charger will want to put out. Might not too. Should be OK with one meant for lithium.
You can probably get away with one made for slightly higher voltage, seeing as your BMS should determine when it's time to cut off the power. (Err...do this at your own risk, mind you!)
Never mind on most of that; found your thread again!
