Every number,side by side.
Output, capacity, discharge rate, terminals, weight and charging window across the entire Advanced Electric range. No marketing figures — these are the ratings we publish on the data plate.
Constant output at recommended voltage
Power, to scale.
Bars are proportional to constant output in watts. Sodium ion measured at 15.5V, LTO at 16.0V. *THE DON is projected at 15.3V nominal from cell testing and AE LV from load testing of the cell configuration at 14.4V; both confirmed on the production packs.

Constant output is the figure we publish on the data plate; burst is listed only where we rate it. * THE DON figures are projected from cell-level testing (24C constant / 40C pulse at 15.3V nominal) and AE LV figures from load testing of the cell configuration at 14.4V, both at 80% amplifier efficiency, confirmed on the production packs. Charging windows and the “set it to” figure match the Support page.

Picking between chemistries
It comes down to your charging voltage. Below 15.2V, LTO can’t reach rated output — sodium ion is the answer. Above 15.5V with a boosted system, LTO’s 50C discharge holds voltage under load far better.
Why burst isn’t listed for sodium
We rate the KILO line at 17C constant and 20C burst, but we publish the constant figure because that’s what the system actually sees on a long note. Burst numbers flatter a spec sheet and mislead a build.
Running more than one
Packs parallel fine within the same chemistry and voltage window. Match cable lengths so they share evenly. Sodium ion is the only chemistry that can share a bank with a lithium pack — only inside the band both windows overlap, charged at the top of it. Lithium chemistries are never mixed with each other.
