Bamboo gt up grade 10s 8p

Hi skaters, im looking for an amazing battery upgrade, 10s 8p , in this way:
Half battery pack below the board, in the original enclosure, and the rest of battery pack upside the board.
For the upside im thinking to cut an evolve enclosure and than modify it.
So im only worried about the original bms, cause im going to fit on a dual vesc 6.6 and I don t know how many A can support the original bms in continuos and in acceleration time.
Can anybody help me?

 

If I was doing such an upgrade, I would stack the battery two-cells deep (using the GTX deck because it's already routed) and use a rubber gasket or 3d printed riser to lower the enclosure and make space. It wouldn't add much depth to the enclosure.

 

Ok but how mant A has the original bms?

 

Not sure, but I don't think the current to the motors actually flows through the BMS anyway.
