I need to decide on a battery to use, and am wondering if anyone has any thoughts on this type of pack:

which looks like a good deal. I think this will give me the range I need 6-7 miles. I plan to pedal along with the motor. 700cc wheels, 140lb rider, rear hubmotor from ebikes.ca.
Thanks!
(I'm looking at building an ebike - I have a 12 mile (24 mile round trip) commute I'd like to take on. To travel the roads from my house to work is a bit, well, insane - crazy drivers, 70mph speeds (legal limit is 55mph...), no shoulder. I figured I could drive halfway, and bike the rest, as I can leave my car at my moms work - it could save me city driving (I don't care too much for Ann Arbor driving). The most dangerous road I'd have to travel on is a 3.4 mile stretch with a 1 foot piece of pavement to the right of the white line, no gravel drop-offs. Slight hills, one big hill.
Range needed - 6 or 7 miles one way in the morning, charged in 7 hours.
I've priced out a bike (Raleigh Detour 3, 700cc wheels), components from ebikes.ca (specifically, rear wheel hub motor, pedal first controller), and am trying to settle on a battery. I think a 36v 10A LiFePO4 would suit me. I've looked at the Ping batteries, emailed Ping, got no response.)
