I've fitted a flying lead to my x-max's battery and have also made an extension for the Ctek's charging lead so that connecting up is a matter of minutes and the wiring is out of the way. I also have an adaptor to charge the car via the 13 pin towing plug as well as crocodile clips for other duties.

For anyone interested in advance news of Lidl and Aldi special offers and promotions, both companies have a newsletter sign-up facility where they will email you in advance of the week's deals, 'middle of Lidl' etc which is useful if you particularly want something where they have limited stock. I've used it myself when they had some nice outdoor gear on offer. You can easily unsubscribe too.

Most of the things in the middle of Lidl come round on a regular cycle but getting to know in advance is useful.
