I have a battery powered speaker system which is powered by a 12V lead-acid battery (7.5Ah). I am looking to increase the amount hours of use I can get out of the unit and I see there are a couple different options. I'm a little confused about each...
The speaker system has a 12vdc 2a charge port on the back. Meant to be used, say, with cigarette lighter port inside your car, or one of those battery boosters with a 12v out port. I'm wondering if I could use a Lithium-ion jump starter to charge the battery. I've been looking at this one...

I understand that this unit is meant to jump start SLA batteries but what about charging them with the 12v out port? Can you charge an SLA battery with a lithium ion jump starter? A little confused here.
Another option....
If I were to increase the Ah by adding another SLA battery inside the unit (wired in parallel ofcourse) do I have to use the another battery with the same Ah? I am looking to keep the unit light-weight and adding another 7.5Ah battery is a lot of weight. Could I add a 4aH SLA battery in parallel? How does the depletion/charge of the batteries work if they are different Ah?
What would be the best way to add more Ah to this unit. Any help is appreciated! Thank you!
