Good to know. I'll pass it on to the Turbo owner for future reference.
Can the battery be changed without a screwdriver? The SP Systems pack
only requires opening a plastic access door to slide the battery in or
out. No tools required.
I computed the 1.7 amp hour capacity from the capacity statement on
Quantum's website which rates the battery at 20 watt hours. I assumed
it was likely 12 volts as is the SP Systems battery. However, after
looking up the spec I see the Sonnehshein/Quantum battery is only 8
volts which gives us the 20 watt hours at 2.5 amp hours. Rated in watt
hours the SP Systems pack is 12 x 2.3 = 27.6 watt hours or 38% more
capacity that the Quantum. There has to be some benefit to justify that
extra size and weight.

Good to know. As I said I'll pass it on to a friend who I'm sure will
be very glad to know this.
