Straight from China is a new 14500 series Li-Ion battery from a company known as SkyWolfEye or as I affectionately put it “The battery with too many nouns.” When you google just SkyWolfEye you end up finding a lot of flashlight reviews and not all of them bad. So a battery with the same name can’t be all that terrible right? Let’s find out!
A long time ago, hack a day did a breakdown on the rechargeable battery that you could buy for the Xbox 360 controller. There really wasn’t a whole lot inside as a lot of your circuit for charging is actually in the charge cable. The only thing that was in the Xbox rechargeable battery is 2 Ni-Mh batteries rated at around 2100mAh, a thermal sensor, and a circuit board which has a little EEprom chip that simply informed the Xbox what kind of battery was installed into it.
In the spirit of the original hack posted by them. We will focus on working with replacing the battery cels in the Ni-Mh charger versus mutilating our Xbox controller. Now, for those reading this and want a super simple solution check out this blog about using just one battery and a diode. For those looking for that total conversion charger and all. Keep reading!
