We are unable to offer lithium shipping to any orders outside of the UK. We understand this is an inconvenience but the complications of transit regulations and the high cost that follows renders it uncompetitive.

We can still provide you with our power equipment (chargers, solar, inverters etc.) and the rest of our range. Thank you for understanding.
