Max g3 custom battery

So i'm shipping my scooter internationally to Philippines from USA, i'm aware i can't ship it with the battery, i'm planning on taking the battery off so i can ship it.

I can probably get someone to build me a custom battery over there, but how about the bms? Would the scooter accept a custom battery pack with whatever bms? Os should i take the bms off from the orig battery pack and inatall that to the custom battery?
