Turf Pro tyres can be fitted for use on lawn grass or where extra traction is needed, for example gravel or poor tarmac. Larger and wider than standard tyres they give a large increase in available traction.
Batteries fitted to Mr Shifta3 are of the semi-traction type, vastly different to the leisure battery fitted to caravans (one reason not to attach a mover to your caravan battery), it will accept more deep cycle charges. We carry stock of semi-traction batteries suitable for all variants of Shifta.
How is it made and how does it work ?
The lead acid battery is made up of a series of identical cells each containing sets of positive and negative plates.
In semi traction cells flat plate construction is used. Each positive plate is a cast metallic frame which contains the lead dioxide active material. The negative plates contain spongy lead active material. also on a similar frame. Both plates usually have the same surface areas.
In practice a typical cell is constructed with many more plates than just two in order to get the required current output. All positive plates are connected together as are all the negatives. Because each positive plate is always positioned between two negative plates, there is always one or more negative plate than positives.
The resultant voltage of lead acid cell is normally 2 volts In order to achieve the voltage required for the application each cell is then connected in series by substantial metal straps to form a battery. In a typical monoblock battery, such as that used in a car for starting, the voltage required is 12 volts, achieved by connecting six cells together in series and enclosing them in one plastic box. Leisure batteries where a sustained current requirement is needed and a deep cycle, the ability to be discharged to 90%, have a different make-up to that of a traction battery that is used in a car.
