Batteries documented to run this
No battery in this catalogue is documented for this device yet, and neither route to one reaches it. Several battery makers publish a fitment rule in thrust — so many pounds at so many volts — and we have found no thrust rating published for this device. Its own maker publishes no minimum battery capacity either, so there is no stated requirement to set a pack’s ratings against. Both are gaps in what we have found, not statements that the figures do not exist. Last searched September 15, 2026.
