The charger should work, there's no difference between the v1 and v2 as far as the charger.
iDS seems to be down though, so make sure that the v2 has a current firmware on it. Chances of being able to update it are slim.
There's a zip file available that contains the 2.10 firmware. I'm not 100% sure, but I think you could get that and flash your v1 with it (just not sure if there is anything about the 2.7 firmware that would prevent it). The latest firmware is 2.12 though, which isn't easily available now that iDS seems to be gone. The v2 should have at least 2.11 on it, probably 2.12. I'd check with the seller though.
