Need BionX Battery & Charger

[GrahamT]

After trying out my friend's e-bike last week, I decided to get one.
I mean, riding his BionX was really cool. Last week I found a used bike near my house and bought it. It looks nice and is in good condition.

But still, I will have to replace the old battery. Because old batteries suck.
The charger cable is torn so would like to change the charger too.
I found some Binox kits and parts from Amego.

But I'm confused about choosing a battery and charger from this list.
I don't know much about this stuff. It'd be great if anyone could suggest a good battery and charger for me.
Thanks in advance.

Are they free or is there a charge for these things?
