I put a battery tender on to charge the 12v to try to get some updates finally. Is it a bad idea to plug the car in? 40amp level 2 of it matters

That seems questionable.

The car will charge the LVB while plugged in AND ACTIVELY charging the HVB if it needs it.

Once the HVB hits target it will apparently stop charging the LVB even if it’s still low.

So given all that having two chargers attached seems problematic.

I thought about it the other day. I wasn't sure the current from level 2 charger wouldn't go into the battery tender. Another reason I dumped the idea was that I didn't see the point of having charge coming from two different chargers all going to the 12v.

Don’t really think the LVB don’t charge and stop charging as your post says.

See page 4 of attached.

Dicking about with LVB using tenders etc in my view is probably more problematic, messing with the mind of the battery management system sez the one with a 110,000 mile, 46 month LVB??ā€ā™‚

Just drive the car or turn down the amperage on the charger to prolong charging time's and thus 12v charging times if you are concerned and enjoy the car.

Don't mess with AI, unless you program professionally in AI.
