Fast battery change in pit stop... need ideas.

[tom255]

Ok guys
I have made Battery Box for my XT8 but its pretty similar as everyone has. Just box with straps. Main issue that now we have new rules and separate 1/8 class for e-buggyes and truggyies. Problem that mains are 20 or 30 min. Last time was 20min.
I have 4S 5000mah battery option right now which is optimal for weight and time. But my setup lasts 15min (15min 40sec before 3.1V LVC kicks).
Have two ways bigger battery or fast battery change.
Big battery for me not OK because of weight and it anyway will not last for 30min with 8000mah battery.
Battery cange took about ~40sec with removing clips and etc then tried without clips and with some training I archived ~25sec, but in rush its pain if strap slips out etc Too much mess.
I thought maybe design box that can be changed without removing a body and disconecting a connector what is simple and fast takes time maximum 10 seconds
I have CNC and can do new chassis from Al and boxes from derlin so any idea is welcome.
First tought is changing from the side, second thought was from the bottom.
Locking mechanism must be a simple. Your inputs are welcome
Thanks and sorry for my bad English
