regarding subject, when i go for-- add to cart, it always show out of stock. than how to order

kp

Yes...I could see them out of stock....But even if the Lipo's are in stock they may not ship it to India..

I just changed my default address to some USA address in Banggood and now the Lipo's are showing as 'in stock'. I am able to add to card and getting shipping option as well.

So, I guess the default setting for lipos for Indian address is 'out of stock'. Even if you try to add, it prompts 'item cannot ship to your location'.

Yes, Banggood does not ship.
AliExpress is your hope.
