You Ask. We help. - Your Questions Answered

Can you use this unit for 400 continuous amps on battery only?
When using the batteries for continuous ground power operation you could pull up to 400 amps. Please note that the batteries are not designed for continuous power. Even at a 40 amp load they will only last for about 20 minutes. Also when using the batteries for continuous ground power if they are deep discharged it is very hard on the internal plates of the cells and greatly reduces the life. If you draw the batteries down to 24 volts they are 95% depleted, if they are drawn down below that you are damaging the cells. When using for starting a spike below 24v for a few seconds is ok.
