This is a warning that the ACE RC MODELS & HOBBIES cannot ship Lithium batteries and that if you place an order for delivery, you will lose the PayPal fee from the transaction and will not receive the item. This is  because shipping LiPo batteries is restricted BY AUSTRALIA POST due to their potential fire hazard, and the ACE RC MODELS & HOBBIES is informing you of the policy to prevent a transaction dispute.
