If you look at that table and calculate the Min/Max values, you will see it is 100% consistent...there is a MINIMUM discharge current of 178.56W, and a MAX discharge current of 249.9W. This is likely because there are banks of resistors in there, and there are only so many they can "disconnect" from the discharge circuit on 2S. I was just very surprised to see the OP able to use a 5A discharge. If that is the case, then the table they show on their website and manual are incorrect/misleading. I did not buy the BD250 specifically because I wanted to be able to discharge at something less than 30A as a minimum. But if the website/manual are wrong, and anything from 0.01-35A can be selected for a 2S battery, I will definitely pickup one of these units. But since he was able to produce a chart that showed a 58 minute discharge time, then it means that 5A is really possible.
The table seems rather useless. If you calculate it, the 29.76V is exactly what you get on the full 8.4V of a LiPo with the max. 250W - given the same, constant max. discharge wattage (and that's what I think the table shows), current will rise with sinking voltage. I don't believe for one second that this is really the minimum discharge setting one can use - would the stupidest charger ever made.
