Courier Help - Sending Batterys to Austria

[.R2D2]

Sold some phones to a customer in Austria which includes 8 batteries. Just had a call from the courier to say they can't send any more than 2 batteries in one parcel. Now for me to separate them and have 4 parcels sent its going to cost a bomb. Is there a way round this or another courier that will do it?

Which courier?
What size/type of battery

We send Lithium Ion to australia very often and can send as many as we like as lon gas they are packaged a certain way, ie cant come into contact with eachother
