My understanding is that battery capacity is the issue; it's usually above the max allowed on the plane. This company makes a snap-together battery https://ebikes.ca/product-info/grin-products/ligo10x-battery.html https://ebikes.ca/product-info/grin-products/ligo10x-battery... where each individual module is below the limit and so the pack can be broken down and shipped individually and separately.
