Dual Battery

[Auda]

Deep cycle batteries are the way to go.
  However, we have a house bus and have used an N150, I think, for the house lights, stereo, computers etc. It has had a hard life being run down to 11 volts fairly often, left to go flat over winter and charged at over 60 amps at times. Its a standard truck battery, has lasted 4 years and cost a bit less than a third of the price of a deep cycle battery. Would a deepcycle one last 10 years ? I dont think so Tim.
  Charging wise the bus has 2 alternators the systems are seperate except that I have a low current switch inside to swap to the bus battery if the lights get to low and a heavy wire in the battery box to connect them for emergency starting.
  I also so have a bettery charger I made from a microwave transformer it will put out 20+ amps at 13 volts and over 100 amps at 10-11 volts good for starting vans with flat batteries.

I have been going to make another one so I'll do that and take some photos.
Is there a way to host photos here or do you have to have them hosted some were else ? Thats a hassel and not reliable.
