I finally received the WhataNut Charger by FMADirect. It's the PowerLab8 model and it has been out in the field for a bit by Beta Testers.
There is not much to say yet about this charger, as they didn't send the usb adapter with the shipment.
I did get to charge my A123's at 30A! Even cycled them once at a discharge of 30A. It's going through its paces now in my garage. AcePow and Enerland lipos going through a storage charge right now. In unbalance mode, I can charge the A123's at 20A and in balance mode at 30A. However, I cannot do 6s unbalance. But no biggie really. At 30A, the 6s A123 pack is charged in less than 7 minutes. I did some regenerative dircharges. Nice feature to have as the charger doesn't get hot from waisting your mah into heat. My car battery got a nice workout. Next investment is a DC power supply with some big balls. More details will follow later on.
There is a thread about this charger on rcgroups.
