To my knowledge, there aren’t any good ones.
You could possibly find a way to hook up some other battery to the brain? But i doubt it would work well, if at all.
I would recommend asking teams near you to lend you one if possible or waiting for them to be in stock.

I have not tried this myself but several other teams have used LiPos of a similar voltage to that of the v5 battery, but of a higher capacity. You would need to also make an adapter from the v5 cable to connect to the LiPo, but that should not be hard.
I believe a 13.2V LiPo is the one teams use, but I am not 100% sure.
