I built up a lighting system with a shumacher emergency car start system. No body had the vector system (Pep Boys and Autozone). The battery fits in my rack pack, I used the 20 watt malibu light. My question is the battery is a 1.3 ah rated Nicad, what is my run time. I have a 14 mile commute one way and my start time at work is 6am. So pretty much in darkness on four lane road.

Thanks
Tim
