WTB 12s charger 50.4v 4-10 amp within the US

WTB 12s charger 50.4v between 4 and 10 amp within the US

I know they have some for sale that will ship by October but I’m looking for somebody who already has one that can ship in the US within several days.

$40 for the tb one “4a”
$80 for the yz power one “8a used twice for 30 mins each time”
