Flashpoint makes a charger that will charge up to 6 batteries at once for the Godox AD200 strobes (or their rebranded versions). At $39.99, the price is discounted compared to its usual price (www.camelcamelcamel.com lists the regular price at $59.99). If you prefer to order via Amazon, I believe it is available to order with Adorama still being the seller. No matter whether you order from Adorama or Amazon, shipping will be charged.
