I had a 120 volt pack and changed to a 144 volt pack so the charger I made
would not charge that high from a 110 outlet. I moved some connections
around and changed a capacitor. Now the open source control board is a
boost regulator. The voltage goes all the way 186 volts for balancing
and the amps are contolled with potentiometer. My batteries are 115 ah
so I hold the charge amps at 11.5 . The charger was woking as a taper charge. The amps would start at 11 and taper off fast as the voltage came up. It was slow. Now I have to reduce the amps after bulk charge . This is
much better for opportunity charging. Most people have at least a 15 amp
outlet I can use. The bulk charging part takes less than half the time as before.
