Great! Keep the options coming guys. There is no one solution that might be ideal for each individual and their needs/desires... I chose the Mastec HY3050EX (1500 watts, 1200 at 80%) because I wanted something that gives ultimate flexibility in a 'clean' package. Others may choose to save $100 and go with 2 Iota supply's.

Also...since I still run a few a123 setup's the Mastech allows me to keep the PowerLab safe at home...

Correct (you already knew that ), 1200 (24 volts, 50 amps) watts is needed to extract 100% out of the charger, per the spreadsheet noted above.

I assume the 80% rule holds firm for any of the above mentioned power supply's, correct? If so, the Meanwell above at 80% (800 watts) would allow the charger to operate at 2/3 capacity or 20 amps output. This assumes you are trying to charge an 8s pack to 4.2 volts per cell.

The spreadsheet is very nice, thanks FMA.
