7-cell, energy-dense battery.
The Dyson Cyclone V10™ vacuum’s lithium-ion battery has one more cell than the Dyson V8™ vacuum, to run at a higher voltage and create more power. But because each of the seven high-capacity, nickel-cobalt-aluminium cathodes is slightly smaller, there’s no additional weight. Innate LED system diagnostics and altitude sensors enable the machine to automatically optimise power to the cleaner head at all times. So suction power doesn't fade.
