Just like the title says, I am building a single XML (lFlex driver) for a friend that has a couple of Magicshine battery packs. I am thinking that I can open the pack up and rewire it to 1S4P (ie: 3.7v, ~8800ma, assuming they are 2200 mAh each) and put them to good use. I assume the packs can be rewired like any pack, but am wondering if anyone knows if the charger will still work with this new configuration. I have searched around and have been unable to find the info, and I do not have the MS batteries and charger in my hands. I would imagine there are a few people out there who might consider using their MS packs this way. Appreciate any insight someone might have.
