One thing to consider when shopping for a solar battery tender is how you're going to connect it to your X3. Don't forget that the cigarette lighter outlet in your X3 will shut off after no more than 15 minutes, and isn't suitable for use with a battery tender. Your choices are limited to battery tenders that connect via alligator clips, or ones that connect to the OBD-II diagnostic port.
