another cmax in Brooklyn!!! hooray!! we've had our sterling gray 201A since dec. 3 and have seen no others. anywhere. we are in the quiet part of williamsburg--where are you?

i love this car. except for a couple of glitches with the battery, it's been a dream--practically drives itself. can't wait for the warm weather to see about the mileage. I'm happy now but expect that it will improve. welcome to the forum.

oops

hahaha!!!!

The 12 volt battery is 12 volts. The LiOn is high voltage. The power in 12 volt outlets in the car is 12 volts and comes from the 12 volt battery and, when the car is running, from a step down converter that converts high voltage from the LiOn battery down to 12 volts. When the car is off, any current in the 12 volt outlets is from the 12 volt battery and the connection to the step down converter is off.

 

Here is what can possibly be done, apparently tested by some posters:

 

A 12 volt battery booster can be plugged into a 12 volt outlet rather than connected to the jumping posts for the 12 volt battery (posts are under the front hood, battery is in back under the cargo area). The booster sends power through the 12 volt outlet to the 12 volt battery, and all that is needed usually is a quick flash to start the car.

i like that answer!  after our car suffered a dead battery for the second time, we bought a jump-starter (by peak, 600 amps) which we haven't needed to use, gratefully.  but if i am alone and ever needed to jump the battery, i would so rather plug it into the 12 volt outlet than work with the jumper cables.  i am assuming that the jump starter is the same as the battery booster yr referring to, or at least can be used in the same way.  hopefully, it will NEVER be an issue again.  that is my dream.

Not that big beautiful windshield! So sorry about that. Big frowny face.
