For the month of July at Sun City Batteries you can get the Thunder Weekender for $480 (RRP $534), when you purchase a 120AH Bosch AGM Battery for $370 (normal RRP $400)

So why the Thunder Weekender?

The Thunder Weekender is a cost effective portable alternative to a dual battery system
Has a 300 watt pure sine wave inverter, 10 Amp 240 Volt socket
You can place it next to your caravan/tent/car and have next to no noise as well as saving on space when packing for your holiday. No smelly fuel and extension cords or even the generator
The internal dimensions of the weekender have been stretched so that you can also fit the popular large deep cycle batteries – larger batteries means more power!
Its accessories are positioned to the sides of the box allowing for a well-balance unit, without a battery. This makes it perfect to access when positioned in the back of a 4x4
A 5 volt, 2.0 amp USB port with the ability to charge smart phones and power thirsty tablets
Has a full coloured LED display that lets you know exactly what’s going on in your battery
