I had the same issue with shipping to the USA. Said the 300 not available in USA, but the 200 was. After I ordered the 200, I got an email saying that the order was cancelled due to shipping restrictions.What is the differrence of 200CC and 300CC?
The 300CC is not available to Portugal.
I order this oneI ended up ordering one of these. Has a battery management system. Decent price. I'll update if it is a POS, lol. https://www.amazon.com/gp/product/B07JQWFS7Z/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
