Adding another 12 volt battery

My fifth wheeler came with one battery but when we lose power it does not last long for the 12 volt lighting. What harm would I be doing if I added another battery and ran it in series with the other one?

  • In series? It will give you 24 volts and the lights will be brighter than you have ever seen them before, but just for a split second.

    If you want to run them in parallel the voltage will stay the same but the amperage will double so your run time will double.
