Hey guys, I've lurked here for a LONG time but I've never posted. On the AceKard 2 review by Urza, there is no mention about the performance of the battery life. Has anyone done any tests on the AK2 compared to standard DS Karts or can anyone at least give me a few estimates on how long the battery lasts with the AK2? Also, does battery life change dramatically with standard firmware and AKAIO? For months I've been using an R4 that pretty much equals a standard cart in battery life and I've been pleased so far. My AK2 just shipped from DX (I ordered two weeks ago , typical), and should be arriving soon. My 4GB Sandisk MicroSD is waiting.
