Q: It's great that Banggood is now supplying this as a spare. You MUST charge your battery with this cable - a standard micro USB cable is not safe, as it does not have the charging circuitry that limits the current to the battery. Using a standard micro USB cable will certainly shorten the life of your battery, and may burn your house down! So if you lose the original cable, you MUST replace it with one of these spares. Even better, it now has a transparent end, so you can clearly see the circuitry and easily distinguish it from any other micro USB cables you may have.
