I see it claims 70 watts out and a little under 36 minutes run-time at
that load, i.e. just 45 watt-hours capacity. From the quoted size I see
that it might accommodate a motorcycle size accumulator, which are
typically 7.5 watt-hours capacity for a 12v SLA. You can get 25 watt-
hours from a similar-sized LiFePO4 cell, but they certainly aren't
fitting those: they retail for $US 260, but they only want 40 bucks -
unless they sell them without a battery fitted.
