bq24703 Two batteries connection

Other Parts Discussed in Thread: BQ24703

Dear TI support

I need to charge 2 batteries at the same time, with the possibility of remove 1. I'm using the bq24703

The spec of the batteries are the same for both:

Nominal Voltage: 12.4v
Nominal Current: 6 amp
Max charge current: 2 amp
Charge Voltage: 14.6v
And I use a source of 15v@6Amp
The question is: Which will be the best way to connect these batteries? I have this options:

Use a bq24703 for each battery
Use just one bq24703 and connect the batteries to the same "Battery Plus" Point?
Thanks a lot for your time and help.

I'm sending you a simple drawing, for you to understand me better.

Best Wishes
