Tubes Plug positions on 2S Batteries?

[Origineelreclamebord]

Hi everyone,

I'm currently working out a top deck/battery holder for my FWD Buggy. The design I have is a big plate over the battery. To connect the battery, it will need holes to clear the tubes plugs. I'd like to make sure though that the plate is compatible with all batteries, not just a certain brand...

So I was wondering, are the tubes plugs the same distance apart on all 2S batteries? And if not, how much do they tend do differ?
