hello all
new guy here and I am wanting to build a powerwall . I have a chance to get a bunch of batteries for a very good price .
these batteries are made by allcell and are lithium ion made from 18650 packs . I am wanting to try to figure out how big of a pack to make . there are 13 blocks of 18650 batteries in each one . If i am reading this right each block is 150ah so if I put the whole pack in parallel how many ah would that be 2100ah seems right if i am doing the math right . so if i do that with 13 of these packs and use each big battery as a 3.7 volt cell I can just run 1 smart bms correct ? If I am thinking this out right this will be one big ass battery. its going to weigh about 1400 pounds. I only have 20 340watt Q.plusl-g4.2 panels to charge this with so i think it will take a while to build and get it balanced but it should run things for a while . I will be charging it usuing the eg43000ehv-48 I realize this will be a very large battery and I am a novice at this but I will be very carefull and I am thinking about building a small building to house this far away from my house . of course I will have to have heat and air in it but thats not a problem . thanks for any info and if theres anyone near wilmington ohio thats way more informed about this stuff that wants to help a new guy out please by all means message me
thanks
