The HypersonicTurboTM system has all the features and benefits of the
HypersonicTM products with the flexibility of adjustable output voltage
and constant power output for your entire run.
The adjustable output gives you the ability to “tune” your battery pack
to your exact need, whether it’s 7.2V or 8.4V all the way up to 10.8V!
While the constant output allows your vehicle to perform at its best
for the entire run, start to finish, with no voltage sag as the battery
is depleted.
Check
out these videos. If you ever wanted to see what happens when you put a
nail through a Li-Ion cell, now's your chance. The standard cell goes
off like a roman candle; the A123 cell doesn't. There's also a video of
the A123 drag bike doing a burnout.
