Hi, this is AnkerDirect.
Thank you for your question and glad to hear that you are so interested in Anker. But we are sorry that we have no plan to produce expanded batteries for LG V20. Now we only have the expanded batteries for iPhone 6/6s, the battery case for iPhone 7 will be available on Feb 2017.
Apologies again for the inconvenience. If you have any questions in the future then please do not hesitate to get in touch.
