content: So, anyone have some experiences or recommendations on the best places online to buy good quality lithium polymer battery packs?I'm looking for premade packs, in different configurations to choose from with protection circuitry.I've got some "Tenergy" 6.6Ah packs (3x 18650 in parallel) from Adafruit which seems to be okay. But I'm looking for more options to choose from. Preferably good quality types from reputable manufacturers.I remember one of Dave's videos he was showing a web site with a large range of them too, but I don't remember which that was.Thanks

content: Be aware with hobby-king, lots of their battery packs are intended for high current RC motors and do not have any protection. (Switching 100A with tiny internal battery protection circuitry is tricky)

content: Protected 18650's is a okay thing, protected lithium polymer just falls flat on it's face...Most LiPO cells are optimized for many tens of C current draw rating but there are some LiPO packs that are intended for transmitters that might be protected (Once again, MIGHT!)

content: We have used batteryspace.com.They have battery packs with protection, and then also just the raw cells.They have also put cells together into packs with protection at our request, and we were only buying a few.

content: The one I've talked about is PowerStreamhttp://www.powerstream.com/They usually have stock, a large range of sizes and types, and price breakdowns. And good quality, not the fakes.Dave.

content: Check this place out:http://hidcanada.com/store/index.php?main_page=product_info&cPath=16&products_id=54I like them since they perform two charge/discharge cycles and label the actual capacity on the battery. It is rated for 3100mAh and all the ones I got were above 2900mAH which is around what I measured on a few.
