Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.

Watch out either case, because if the battery is connected to the meter through a boost circuit then the ripple could cause even more volatile reading, but if you connect the battery directly then the voltage could be too low for an accurate reading (these instruments are callibrated at their rated voltage).
