Yeah I’m familiar with Ariane 6. It costs almost double what SpaceX changes external customers per launch, not even counting that their internal rate would be even lower. Plus you’d need more launches since the payload capacity is lower. You’d end up paying 3x or more the cost. At that point, why not just buy falcon 9 launches? Otherwise it seems like there’d be very little way to compete.
That puts it at a 12C charge rate. The question is how the batteries will hold up over time. Does each fast charge cycle make a noticable degradation to the capacity?
If they’re using LFP it’s probably okay, they can usually take higher charge and discharge rates at the cost of lower energy density. But I’d be worried if they’re pushing NMC battery chemistries to 12C, as I think that’d kill the life of the battery.
