Do you have a link to the batteries?

Thanks cheese. I forgot make "this" bold haha

Sorry friends I fixed styling for links now

so ... will it works?

Yes that battery will work. However, it is a pretty large battery and you will need two of them for a 7.4v battery pack.

This is my go to battery for flat cells http://www.batteryspace.com/polymer...wh-10a-rate-ul-listed-un38-3-passed-ndgr.aspx

Depends on your load and efficiency of your regulators. Everything from the audio amp, screen + backlight, motherboard, controller, all take power.

If you can calculate your draw from all these things you can find how many hours the batteries will last.

Would you mind sharing a link to your go to batteries for cylindrical cells?

 

[bentomo]

I've found batteryspace's site a little difficult to find things sometimes. I usually have to google protection circuits just to find the basic ones for cell packs.

From here you can go through cylindrical or flat packs.

Batteryspace is awesome however their products are more expensive and their shipping is very expensive. This ebay link sells legit batteries that have worked out well for me so far http://www.ebay.com/itm/121611468285?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

Now if only these shipped to Canada

Now if only these shipped to Canada

Yeah, was just thinking the same thing. I found a similar model from what looks like a reliable seller, good reviews and ships out of the US, shipping is only $10. These ones are protected though so are a little taller.

I would offer, as this store is so close to me, however, USPS forbids shipping batteries outside of their intended housing internationally (as stated in their policy here). That's probably why they don't ship to Canada as well...

These ones are protected though so are a little taller.

Actually, they're not. In the description it says there is no protection circuit. In fact, they're actually the exact same model as the US only ones above (18650 size, model MH12210).

 

[ByteMe]

Yeah that seems to be the reoccurring issue, to get around that majority of places ship straight out of china, less restrictions. Thanks for pointing that out, even better! I probably should've checked a bit more throughly, just read one review saying that they were protected.

Just wondering, I don't know much about batteries in general. But when it comes to protection circuits how much does it matter which ones you get for your specific batteries? And are there ones designed specifically for 2, 4?

You have to get a protection circuit that corresponds with the voltage of your pack. Since a li-ion cell is 3.7v you would need a 7.4v protection circuit if you have two cells in series, and a 14.8v circuit for 4 cells in series.
