This is such a stupid, embarrassing error to neglect the kWh on your own launch brochure. By the sounds of it, pack is likely 14s. To deliver 15kw it's going to be doing at least 300 battery amps. Sounds possible, but unusually high. Math doesn't really work out with 18650's though, 3ah cells means this would only be 14s15p, borderline for doing 15kw of output for any sort of decent lifespan. It's something I would do for a hotrod project, but probably wouldn't recommend for an actual product. Possible it's some kind of higher power output prismatic cell or a power focused 2170
Charger seems pretty anemic for this kind of product, much, much worse than the Surron? Really?
