100 W
I recently got a small Travel Trailer, a Casita 17' and I am thinking of adding a Li-Po and some Solar panels.
I have about 370W of solar panels, from another project, lying about. I will need a 12V battery and controller. I am aware that I can use the Lead-Acid batteries that are currently in it, However, there are a lot of advantages of Li-Po.
My needs are the water pump, assorted LED lights, probably some amateur radio, a CPAP, and the possibility of want to charge a 60V electric bicycle.
The water pump will probably see about 10-20 minutes of use per day 12V @ 4.4A
The CPAP will probably see about 7-8 hours per night:
As far as the e-bike, I suspect that I will be better off putting a separate charge controller in for it and running it parallel to the house charge controller. But that is not stage 1. Stage 1 is the house power.
I have not built a battery before. I could get a spot welder if I needed to. However, I see a lot of 12V 30,000ma/h batteries on Ali-Express. I can't help but think that about four of those in parallel and I would be done.
Any suggestions on cheap 12V that will meet my needs?

I will not die if it stops working. But I won't sleep well at all.Input 12V/24V 13/6.5A
