RC10 fast battery holder ?

[mendocino]

Hi everyone!

Next month, my little club organizes a 6hours endurance race

We'll participate with a vintage RC10 (alu chassis). I'm currently thinking on a fast battery holder system.

I'm not looking on a hardcore system, as fun is the most important thing there.
We will just use deans plug to save some seconds, but I'm still struggling with a simple yet effective way to attach the battery.

I've tough about some ideas but nothing really stands out...
So, I'm wondering if anyone here has done such a system or just has any ideas!!

Thx!
