Ug. This has been talked about before and unfortunately it seems like it's going nowhere.

We desperately need a quick change system because even the slowest Nitro guy can "win" in a 20 or more minute race. We can stuff race ready trucks with packs to get us to 15 or 20 mins max but if you go beyond that, you either have to use enormous packs which are not race weight or you have a pit stop that is about 2 minutes long (for a dual pack truck).

I hope that OEM's decide to make a system where you solder your battery leads to some kind of sled which pops into a mount built into the vehicle.

As Electric 1/8th becomes more factory and less home-brew there is a chance for a system like this but somebody has to invest some time, money and a whole lot of risk in order for it to see the light of day.
