As far as I’m aware, these chargers are apparently only available from two suppliers -
Li-ion Wholesale has both versions of chargers available for purchase. But Enovapura seems to have the S4000 Pro model only at the moment.
I was looking at getting the S8000 model charger, but it seems that Li-ion Wholesale does not ship outside North America for this charger? I’m in New Zealand.
So is it possible to purchase the S8000 charger elsewhere by any chance?
