Mine arrived now, Wed 1020 from their Netherlands warehouse. Ordered Friday 2130, I got a mail on Sunday saying order was being dispatched. It was delivered by Royal Mail ParcelForce and the box had a large label saying “Lithium Ion battery” with instructions not to pack it / ship it if the box was damaged. ParcelForce say they do not handle Lithium batteries unless attached to or with electronic devices.
" Batteries, specifically new and used lithium batteries when not sent with or connected to an electronic device. No "
My previous 4S1P came with 5.5mm bullet connectors, this one is bare wires with standard JST XH balance connector.
