dnmun said:maybe this is the first charger you ever owned. all the charger fans are noisy. except maybe the headway charger but it is on 3.3A anyway. by screw i assume you mean the trimpot labeled R15A? it most probably is used to set the final charger voltage. i think i have contributed a small amount to understanding how chargers work and how to maintain them. i even know how that one is gonna fail, but you will find out when it happens so why spoil the fun?
if you can get a battery to 240V then maybe worry about the plug but most people use better connectors anyway.
Well, my Gaozhao Charger charger stopped working the other day. If my multimeter is correct its outputing about 80vdc when it should be doing 60vdc. The first sign of issues was the fan getting much louder than usual. Maybe getting to much voltage. The last time it did anything when plugging in the battery was louder and louder fan for a few seconds then stopped. Now it doesn't even attempt to charge. Do you know what might be causing these problems?
