I'm going to stick one of these in my PTW M4s buffer tube but I need to know how to charge it lol. I have a LiPo and a charge ballancer but in the pictures of this battery I only see a small type taimya connector, not the wide type multi pin connector on the other LiPos I've seen. So how do you charge this battery? Or is there a second connector on it that is chopped off in the pictures?
I just ordered 3 for half the price of one 12v PTW battery... I guess this retailer just has poor photoshop skills and chopped the second connector off in the photos. I hope I can cram one one in my MP5K monstrosity one i get home from the sandbox.
This thread would have gotten noticed faster in the AEG board...
I've been using Lipo packs for a couple of years now, and I have had several of the Firefox 11.1v packs. I don't know whether you've looked at the main site here at Trader's, but I have 2 videos I posted showing me installing and using this very pack in my PTW M4A1 MAX gun. Feel free to check it out:

You charge the pack via the connector you would normally use to plug into your gun, the same as a 'regular' AEG battery. The small additional connector you see sticking out of the pack is referred to as the 'tap' and it's used for the balancing portion of the charging process. The tap is supposed to be plugged into the balancing harness on a balancing charger, so that it can regulate, or 'balance' the state of the individual cells as the pack charges. This would NOT be the spot to try and charge through.
I'm actually going to be doing some work on another PTW for someone, to rewire the tube wiring to properly fit this pack into the stock tube, so that they can use a mil-spec real steel stock. You really need to remove the 'telephone cord' harness from the FET board to get the additional room you need to put the pack directly into this tube. Even then, because of the space the FET board takes up in the tube, the Firefox pack will still stick out a couple of inches out of the end of the tube. This simply means you won't be able to fully retract your stock, but for most people this isn't a big issue, in order to gain the ability to use whatever stock they want.
I've also successfully done this modification on 'regular' AEGs, so that the pack fully fits inside the stock tube. Junior, one of our members, currently owns one of the guns I modified this way. Good luck with your project!
