18650 cell powered electron

Hardware

I’m looking to power an electron from a few 18650 cells, given there is a liPo circuit in the electron do I need to be concerned about having a protection circuit built into the cells? And should I be concerned about balancing the cells / any other issues?

Thanks

Ideally, you do want to protect multiple cells from overcurrent and over and under voltage conditions.

Here is a range of pcm's for single cells packs.
