I have the Hyperion 720i DC $100 like NEW here on RC Tech and a Mean Well S-320-12 power supply $40 and I could not be happier. If I was to change any thing I might look at a Hyperion Dual. I was using a Triton EQ 2 which is AC/DC with no complaints. Reason for upgrade is the new Nanotech & Gen ACE are now charging at way past the old 1c rates; 5c capable.
I may not be as electrically knowledgeable as some the other racers, but I do enjoy research. For quality, reliability, performance, functionality & Price the Hyperion units were always rated at the top. This Site has been excellent source for Quality info numerous projects & problem issues. There is also a battery test on the internet at this address http://www.bigsquidrc.com/lipo-batte...rger-shootout/
I have never had the need to go beyond the 4 cell Lipo's so my info was within that range, & I have never owned the a power Lab unit. I have owned Turnigy Accucel-8150 & A30 power supply, Thunder AC6 Ac/Dc & MRC brain 992 charger & power unit.
