This is currently the charger I have

The thing is it takes forever to charge anything up. My 800mah cx2 2s lipo takes 83 minutes to charge.

My 5000mah 3s batteries take about the same time.. Sucks when I have to charge two to run my flux.

Anything I can do to get this thing working better or is a new charger the best route to go?
