I wish something would be done about the quotes locking up browsers AAAAAAAAAAAAAARRRRRRRRRGGGGGGGGGG!!!!!
ok,,, as I was saying...
jtice goes to retype....
Thanks for the quick and thorough response.
Perhaps I'm wrong, but I was under the impression that the Li-Polymer batteries were somewhat flexible. I envisioned them conforming to the curvature of the inside of the helmet. If they do, I think there'd be enough clearance so that the straps wouldn't touch the batteries.
hmm, I have never heard of actual flexible cells,
that would be really cool if they are though !
Let me know if you can confirm that, and how flexible they are.
Interesting. I didn't know about the venting. That rules out dipping the whole battery pack in that rubber/vinyl stuff. What type of epoxy is appropriate for coating the PCB? Where is it available?
I THINK the Stenlight packs are dipped in rubber,
but I am not sure what portions of them are.
Also, I dont know if that would hold back the vented gas or not.
Would be nice to know, I would like to use it if its safe.
So the matching process is just making sure that the 2 batteries are in the same state of charge? That's not so bad. I was afraid I'd have to find 2 batteries with *exactly* the same discharge curve or something.
Its not a big deal with Li-Ions,
due to the voltage representing the charge state real well.
Since you are buying them new, just get them the same voltage.
Now, adding a new cell to a 2 month old one is another story.
Then they would probably have diff. discharge curves.
Probably not that much. I figured it'd be good to have more than one battery pack, and I thought it'd be fun to build the 2nd one myself. If the 6000mAh ones will fit, I'll have a very comfortable margin of safety.
Oh, I am not saying it wouldnt be nice
more is always better, especially if you arent increasing the packs weight/size much.
Keep us posted on how it goes !!!
