Commercial Engine Start


Manufactured in the UK and designed specifically for the professional user, the Red Flash™ Portable Power Pack range is suitable for starting most 12V and 24V engines – automotive, marine and rail.

All our Portable Power Packs incorporate safety features to protect both user and vehicle. Surge and spike protection circuits reduce the risk of damage to the on-board electronic systems and the On/Off isolator switch means power is available only when you need it. The use of fully insulated cable clamps, welding grade cable and highest quality batteries ensure the unit can be used in the harshest conditions and can start the most stubborn of engines.

The polyethylene case is extremely robust and will protect the internal batteries and electronics from damage. The case is also fully resistant to oils and contamination found in workshops.

* Many alternative product specifications state the short circuit current of the batteries. DMS believes that although this allows some comparison it does not provide an indication of actual engine starting performance. Engine cranking performance is therefore provided which is defined as the power or current available for 5 seconds to a minimum voltage of 7.2V at the croc-clips at 20┬░C
(14.4V for 24V packs).
