Prius plug in high voltage battery cells

That's the two nuts that connect to orange cable ?space between nuts ?

 

They look offset too the modules funny lokin

 

It is exactly 80mm apart.

 

If you're planning on an upgrade to more modern and advance cells to double your EV range @jacktheripper is telling me that the price he bought his PHEV cells for in large quantities a while back have nearly doubled in price and then there's stupid tariffs on top of that.

So if that's why you want to know the measurement I suggest you buy from him: http://www.saltyhybrid.com/collections/all-products/products/2012-2015-prius-plug-in-lithium-upgrade-pack because he still has 3-4 packs left because early PHEV are not that common, so not many potential customers.
