I had that one in the cart ready to buy until I came across a smoking deal. I ended up getting the Hyperion 615i Duo3 that has 2 charges on it and comes with everything new in the box plus extra balance taps and charge leads all for 140$ shipped. I could not pass that up. Since it is a dual port I now have 4 chargers capable of 10 amps, 15 amps, and 20 amps. This will work perfect for me.
This is the power supply I made and use.
