12/24 Volt Jump Start/On Board Power System

Have you ever attended a breakdown to find that you need 24 volt on your 12 volt service van? Do you have to keep swapping over batteries to create 24 volts to jump start a truck and back to 12 again to charge off the vehicle? Has a previous technician shorted the 2 leads during swap over and blown the charging fuses? Is your jump pack always flat as someone forgot to put it on charge, again? If this sounds familiar then we have also fell in that trap too so you’re not alone!

This is why we decided to manufacture a solution. Our jumpstart unit combines the vehicle battery with 2 additional batteries automatically providing charge to the 2 auxiliary batteries when the engine is running. There is 1 jump start socket which permanently provides 12 volt (system does not need to be switched on to provide 12 volt jump start facilities). With the engine running, the system is switched on automatically. Switching on the isolator prevents accidental selection of 24 volt and it also disconnects the vehicle from the auxiliary batteries. Pressing the 2 voltage selection buttons with the isolator on switches the voltage supply at the jump socket between 12 and 24 volt. Turning off the isolator will drop it back to 12 volt automatically and reconnect the auxiliary batteries back to the vehicle to continue charging the batteries. There is also a warning buzzer in 24 volt mode as well as a voltage read out to provide a visual and audible warning of what voltage is at the socket.

Another bonus is the batteries you use are your choice and can be of any capacity or dimension. For large commercials we would recommend using the 629, 624 or 625 batteries. For smaller fleets we would recommend the 663 or 664 type batteries. Being a lead acid normal cranking battery means replacements are not expensive and easily tested and replaced as well as being available off the shelf at almost any auto electrical retailer.
