I've finally been able to pull the cells out I bought last year out of storage and build my battery banks. My concern is that there is a difference between cells. None have been hooked up and the only exposure they have had has been seasonal temp changes. Each cell is 305ah and all showing 3.30v.
Please correct me if my process below is wrong:
The only steps I have left are:
1) Compress the cells in place
2) Mount BMS
3) Connect BMS to cells & connect cells in series
4) Review configuration/configure BMS
5) Connect BMS to + & - bus bars
associated with CC's.
6) Review configuration/configure CC's
7) Connect CC's to panel arrays
8) Let CC's charge cells until BMS stops charging (I don't have an alternative to charging the cells and the bench charger is to slow to my understanding for this part).
9) Disconnect the BMS from the CC's, Cells, and disconnect the cells from each other.
10) Connect 4 cells at a time in parallel and use the bench power supply to top balance the cells to 3.65 (when the power supply shows no current is being drawn the cells are fully charged)
11) Repeat step 9 until all 16 cells have been top balanced then make sure all cells are no longer connected to one another
12) Repeat steps 3-8
* If all is good then repeat for send bank and connect in parallel
