Hi Leroy here and I'm new to the forum.
I planning on building a 12 solar generator for camping. And maybe back lighting if the power goes out at home. I want to build a lifepo4 battery but as you all know these are costly.
There is a local seller of Prismatic cells here in NZ that are well priced with 3.2v and 50AH cells. 50Ah is enough for this summer but ideally I would like 100-150AH. But having at buy a the other parts of the set up as well is expensive.
Is it a dumb idea to start with a 50AH battery this year then next year but some more cells and add them in parallel to the existing batteries? Or are they like bricks and you are better off using cells all from the same batch to avoid balancing issues?
Thanks for your help
