Extra battery VW T6

[smilingit]

Hi,

I wanted to add an extra battery under the passenger seat on my Ocean. Is it possible to connect with the existing battery under the drivers seat in series? If so, is it a relatively easy procedure? Anyone done and has a report? Any idea of costs?

NOT in series. That would give you a 24 v circuit.
In Parallel only to give you a 12v circuit with double the capacity.
Both batteries should be the same type, capacity and age.
