It says dean's connector and SparkFun has M/F Deans connector on recommended product. So I will drill 2 holes, and solder the male Deans connector on PCB?
I'm not sure this is the best idea...</p></p>

I accidentally left one of these packs connected to a prototype and managed to discharge the entire pack down to 2.2V! The poor thing was so swollen it actually broke out of the black plastic they're wrapped in! It was seriously twice the size of a normal pack.<p>I figured there was no fixing it, so I cut the cords off and properly disposed of it. I made the assumption there would be under-voltage protection at the very least; don't make my mistake! If you're planning to run these batteries raw on an Arduino or some other type of MCU, hook the output to a voltage divider and monitor it in software; once the battery hits 6V have your system turn everything off and go into the deepest sleep mode it can. This is the bare minimum I would recommend with these types of batteries.</p><p>I'm now working on a nice little protection circuit that will monitor these packs with a chip from TI and then shutoff the output (via a FET) when the voltage gets too low.</p><p>TL;DR: These packs have no under-voltage protection and can be discharged down to a point that permanently damages them. Be careful!</p></p>
