I have a battery charger that can charge 4,10,20,40 amps depending on what you choose. This would be perfect to use for testing my Fuel Cell. Anyone know if that can be done? I tried it but it faults. The fault code given is F02 which in the manual that means there is "bad connection, battery voltage to low to accept charge" It would work perfect on the battery beings it has a charge positive and a ground on it. Anyways if you have any ideas on how I could get this to work that would be super! thanks
