Yeah a lot of chargers have pretty weak discharge systems. They get the job done, but it's very slow. I think I might look into getting a discharger as well. I really want to hear back on that one that
@cordell12 ordered.
One thing to keep in mind with charging and discharging amperage is that just because you can set the charger to a certain amount of amps, doesn't mean that your charger can do that much for the battery size that you have. Your B6AC and my Hitec X4 AC Plus have 5 watts of discharge per channel, which for a 4s battery equals approximately 0.3 amps of discharging. That's why I do all of my discharging on my Hitec X2 700, which has 30 watts per channel, so I can discharge a 4s battery at about 1.8 amps.
