Battery Cell Decisions, decisions (for the folding board)

Hey, y’all,

As some of you know, I’m the guy who built a boardup board for travelling. Specs aren’t amazing but the most important part is the form factor. Anyway, I’ve gone travelling with it already, have figured out what I need/want from it, and range didn’t really bother me but I did come up with the idea that I could do quick swap battery “cartridges.” That said:

  • the battery in the board will always be a 10S1P; I think shaving off 400-500 g is worth it. After years of experience, I can tell the difference carrying the thing around
  • drive train is DD; 20A per side, I’ve found this is a good sweet spot for this board.
  • the board is NOT for long rides; probably ~5km the furthest in one go. It will be folded and carried past that…until the next point where it will be ridden again.

I need a bit of nudging into either direction on deciding which cells to use, believing I’ve found the best source available to me without an ABN here in Australia (we’re a real place):

Which cell should I use?

  • 20 x P42A at AU$11.56 per cell
  • 20 x P45B at AU$18.45 per cell

That said, I’m also open to other sources (links welcome). I do not have an ABN.

I don’t know your battery current for that setup but for 10A-20A for a 1P pack the P45B will give you about 10%-14% more run time. Up to you whether that’s worth the extra cost. :slightly_smiling_face:

That’s why I’m asking. I’m aware of the points you raised but I could see myself going either way.

Its worth to do P45B since you only need to buy 10 cells. I am considering it if i ever need to build a 10s1p in the future. Go for it.

My personal choice is to always go with the better performer. For me the cost doesn’t matter since I get to enjoy the better performance every day for a couple years, hopefully much longer than that

Are those imported or local sold cells?

Locally sold. Importing is not worth the hassle. And uncertainty.
