What type of cables do I use to connect 4 12volt batteries to my electric bike?

best electric bikes in uk image

Q. Hi. I'm trying to connect four 12-volt batteries together (I think they're supposed to run parallel), so that I can power a 48volt, 500watt motor.
I'm not very electronically/mechanically minded....so I'm not sure what exactly to use to connect these batteries. Would some type of clamps work? The batteries have little prong ends, not the kind like car batteries with the hole ends for big screws.

Thank you for your help!

Answer
For a 48 volt motor, you will need to connect the batteries in series. + on one to - on the next one and so on (see series drawing here):

You will need heavy gauge (10 ga or larger) battery type wire with ring or spade lugs for attaching to the posts:
