Previously I took my Boosted Board to the Grin Technologies office nearby for Justin and Robbie to check out:

I was complaining to Justin about the dismal range and he said to hack it.
So I did!
I bought three of these prototype packs of 10s 18650 packs with bms and stuck them in hollowed out ethernet switches:
I hacked into the discharge wires and plugged them into the Boosted Board:
I also bought a Grin Tech Cycle Satiator to charge the blue packs to 42V plus as a bonus I can use the Satiator to work as a second charger for my boosted, charging at 2.7A to 43.2V through the charging port, or I can charge the Boosted through the discharge wires at 8A! This allows me to get an 80% charge in ten minutes which is totally wild (A123 cells are famous for their ability to accept and dump out charge at a high rate).
And here's the money shot:
15 miles on one charge!
I probably could have gone further too, I terminated the charge at the end of the constant-amperage phase instead of waiting for the constant-voltage-decreasing-amperage phase to run because I was excited to go for a bomb around Stanley Park.
