is lipo ok?

Post by slip »

is it ok to use lithium cells? and if so how much voltage can each spoke, or 3 combined, take?

a single 3.7v lipo battery is fine.

So, just to be clear,
You can run a Spoke POV off one of these:

?

Will that be enough juice to power blue LEDs?

If so, then it looks like it would be a way better option for weight and waterproofing.
What would the drawbacks be?

Thanks,
Dan

Awesome - that is great to know.
One more question.
If I wanted to put 3 blue Spoke POVs on one wheel, could I power all 3 of them with just one of these?

That would be suuuuuuper convenient! Way better than 9 AAs. :)

-probably- but the battery would not last terribly long. youll have to test!

So I went ahead and ordered some Spoke POVs along with a few Lipo batteries (3 small & 1 big).
Questions...
1) Do they come with male/female connectors? (i.e. The bits I'd need to wire the batteries into a circuit).
2) How do I wire them up to the Spoke POV?
3) Would I need to add any resistors or anything extra?
4) Has anyone else tried this yet?

Thanks,
Dan

you will have to make your own connector for the spokepov but you should just be able to connect the lipo to the power input jumper near the top. you'll need some JST male connectors

Awesome. :)
Will I have to cut the trace on the board if I plan on using the LiPo to power blue LEDs?
