SP 140 Battery specs

Are my assumptions here correct:

100V - 40Ah battery = 4KW ???

My understanding
ideally (P)ower = (V)oltage x (I)current

Ah is the capacity – 40 amps for 1hr

So 4kw for 1 hr Assuming you would get 100v for an hr.
But as the battery drains the voltage drops thus less power.


The sp140 has an 86.4v nominal (basically average volt) battery. The capacity is 46.2Ah. This gives us a capacity of 3.99168 kWh which they round to 4kWh.
