Meepo 40T vs Ownboard 30Q battery DIY?

I may be building a Foosted copy DIY e-skateboard from the ground up.

Does anyone have any feedback on which one I should get?

Option 1 - Meepo’s Samsung 40T - 10s2p. 8Ah . (I really like the enclosure). Option 2 - Ownboard Samsung 30Q - 10s3p. 9Ah.

I would like to have the battery with the lowest voltage sag and longest range.

Any comments?

Between the two, 30Q would give you more range & the same amperage.

Its also a bit bigger, if he cares about that.
