Lectric 3.0 folding step through battery w/ four terminals

[Santa]

I’m an old mechanical guy, electronic not so much. Maybe all the e-bikes have (4) terminals, don’t know. What are the (4) terminals for . I get it -positive and negative for the motor. Sorry if this seems like a dumb question Educate me. Thanks

Most batteries have four terminals, and often it's two positive and two negative. Some of them only use two and leave the other two blank. Probably saves them on labor because they are hand soldered.

You got some outliers that only use two power terminals and run their own circuit apps thru the other two pins.
