I am building a small 120Ah 12v battery, from those very common blue Chinese aluminium cased cells. ?
During initial charging/top balancing to 3.65v I noticed cells swelling. They are 3-4mm thicker from middle compared from edge.
iam guessing this is normal.
I placed about 2 mm thick wooden stick sandwiched between double sided tape between cells so when i tied the cells together they are touching from the edges and leaving 0,5-1 mm gap in the middle for additional swelling.
is this better for cells or should the cells be clamped together more tightly to prevent swelling?
