well the Battery has finally arrived.
The first one got stolen and the American company sent another, premium class and it arrived in 4 days.
had to do a little rewire and a relocation. I will post pictures later.
This Lithium battery can only take 14.4 volts max and when I tested the bike with a spare battery it went to 15 volts so I have bought another reg/rec to hopefully get this down to the 14.4 volts.
