Where to buy a large, reliable triangle battery

I am in the market for a large 14S >= 25AH triangle battery. Unfortunately em3ev only carries the 6p pack now. Does anyone have any suggestions?

Thanks

Maybe UPP

Or, best of all, find a reliable source of the cells you want - genuine, grade A and fresh - and

a pack builder local to you, at least on the same continent

or buy a spotwelder and learn to build it yourself
