I fitted a Odessy battery to my Exige. I have layed the battery on its back but it is a struggle to get all the cables together and bolted to the terminals.
I have seen the L adapters Odessy sell but I am not sure this will solve the problem.
Just wondered what sort of mountings and connections other people were using.
Got a bracket sorted out and re routed the wiring to make it easier to connect. I left the battery bracket in place so the battery sits higher up so it is easier to reach.
