Can I charge the lvb and hvb at the same time?

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??‍

You don't need to charge the 12V battery to receive updates. That's not how it works, doesn't make a difference.

Lvb state of charge is one of the few update requirements

For it to install, not download. Just schedule it and let the car charge it up automatically.

I thought o remembered that from one of Mach-Lee’s posts. Sorry about that.

No it won't download without the lvb being charged either

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.

Professional, and AI, in the same sentence?
