The other way of using our batteries. We provide the reference that has been sent from our customer, Mr. Nikolaus R., Hundheim, Germany. The photographs show the approach and solution used by Mr. Nikolaus. He wrote: “I want to present you the way I changed the battery of my mobil home, which is an ARNOLD Oldtimer on a frame of a Mercedes 308 built in 1980. In that time it was a luxury mobile home. I bought it 8 years ago, to use it as my "hotel" and "office", when we are on tournee with our little puppet‘s theatre .
