Battery Pack? Answered
I want to build a battery pack so that I can charge it with solar. i bought some 12v 1.3ah sealed lead acid batteries but they don't do the job that I want to and they are not very appealing. So I have seen the tesla powerwall and it is great and also slim, so what I want to do is to buy different batteries which are the panasonic 18650 and the stack them together to my own specifications so that they can power small things such as lights and pumps. The packs that I will make would be small at first just to test and have an idea.
So is it worth investing in these battery types or just buy some sealed lead batteries and then stack them together.
