Starter Battery Low: Won't Install Update

I posted about this before, and ultimately my car charged itself enough via driving to install the past software, but I can't find the thread anymore, and I searched google/here/reddit/etc.

I recall someone sending charging instructions. I have a 12V trickle charger, but I thought the starter battery here was 48V.

Is there anyway to boost this as I don't have any long haul driving ahead of me.

Main starter is 12v. The auto start stop system is 48v.

Your owners manual will show you the steps to charge “jump start” your car.

As mentioned above, the starter battery is the 12v battery. That battery is used for cold starts and the 48v battery is used for the others.

You will want to connect the charger to the terminals under the hood and keep the hood open while charging. The 12v battery will be charged and if your charger is running at at least 20amp then the 48v battery will be also.

May I ask if you know the 12V battery is AGM or lithium battery?
