Battery recovery, repair and charging
Charge any battery, even if you don’t have the original charger
Electroplating
Anodizing Aluminium and Titanium
Electro-polishing
Etching
Electrolysis
Operate DC solenoids, valves and pumps
DC motor speed controller
It’s a DC power supply with programmable CV/CC constant voltage/constant current. A more professional 80V/5A version of this tool would cost kilobucks. We can build it for about $40, because we’re not concerned about electrical spikes or noise.
