Hello Pilots !
I thank you for your help and feedback.

I ordered a few lipo batteries + charger at RCBazaar : not only the cheapest but especially the only one that could charge my credit card.
Though international, I have 1 mastercard + 1 visa, but I was unable to order in : RC Dhamaka, Kinetic Hobbies and other suggested sites -> authentication problem.

By the way Paypal is not accepted, nowhere in these shops (though proposed for foreign currencies in RCDhamaka but not working, unable to transfer money from Paypal to the shop account).
I thank you once again guys for your help !!
