Hi what size battery should I use for a bec build?
I know the bike has a small battery but I presume the electric reverse is going to take a lot of cranking power considering it's got tho move the car and person!

What cranking power if a battery should I be looking for?

I have a BEC with a racing battery, it has an electric reverse based on what looks like a motorbike starter. I also have a trackside battery connector on the dash. If I am planning on doing a lot of reversing then I pug in a battery pack while doing it. That eliminates the weight of a substantial battery just for reversing. However I hate using the electric reverse, it is not well designed and sounds like a spin dryer with marbles inside. The racing battery gets me out of tight parking type manoeuvres but don't plan on more than 20yards usage.

I have a Varta B34 330ca, fits nicely in the passenger foot well with plenty of leg room.

Hmm couple of options then.
Just wanted to keep weight down, and a bike battery would be enough for the running but wasn't sure it was good enough to do the reverse aswell, bet it takes some power to reverse the car

As long as you keep the engine running it shouldn't be too much of a problem
