I need a good 72v vendor

Hiya people, I'm a paraplegic and super fortunate to have a life changingly good Bowhead Reach. The cyclone 3k for such a capable beast runs best with 72v 50a continuous. id like more ah/wh. Normally use the great em3ev for 52v packs but I'm new to the 72 world. Who can I look out for?

Cheers

WB

I would run a battery that could do 80amps or more. Headroom I'm would like to find a good vendor. Bicycle motor works made me a 72v 24ah battery only ever got 18ah out of it at 50amps. Don't go there 1,200usd triangle battery. Made of Samsung 40t 30amp cells 6p. Or counterfeit cells. I like the BT bms.
I might have to buy a spot welder.
Also looking at Calibike ? I never brought from him

Thx I'm uk and thinking good welder also

FWIW CaliBike was a UPP reseller and had a lot of generic packs. I'd be certain to clarify the claims.

I’ve got a bunch of a123 cells and bms for 24s or 22s and could weld u something whatever shape u want for cheap
