One of the key components of Li-ion batteries is the busbar, which plays a crucial role in ensuring efficient and safe operation of the battery.What is a Busbar?A busbar is a thick, flat metal strip used to conduct electricity within a battery pack. In lithium-ion batteries, busbars are typically made from copper or aluminium and are used to connect the individual cells within the battery
Compared to copper busbars aluminium offers a weight and cost save, but requires an increase in cross-sectional area of ~62%. Hence aluminium busbars need more volume for packaging. Paired with its low specific weight, it is not by chance that aluminium plays a vital role in state-of-the-art lithium-ion batteries.

This was probably fine but had to be confusing to the converter/charger (for Lithium batteries) which would eventually go into float mode when all were charged. (Although a few times I noticed it switching to float before 1 or 2 were fully charged.) This is probably a symptom of undersized wires and different distances to the bus bars.

Bus bars (busbars) are short strips of conductive metal for high current electric connections. While our renovation of a 1970 Avion truck camper generally deals in low current demands, we are building a DIY lithium battery
We are continuing our deep dive into bus bars for our DIY lithium batteries. Bus bars (busbars) are short strips of conductive metal for high current electric connections. We are going to use some to connect the battery cells in our batteries. While the concept of a bus bar is simple, getting the right bus bar is nuanced.
For a 14-series, 9-parallel lithium-ion battery pack, the busbar sizes have been taken as 16 mm 2 based on the industry standard current density of 3A/mm 2 (Total current: 48 A).
The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2. The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed electrothermal analysis.
The manufacturing processes for copper busbars are intricate and involve several critical stages to ensure the final product meets high standards of quality and performance. Each step in the process is designed to transform raw copper into a precisely engineered component suitable for various electrical applications.
Compared to copper busbars aluminium offers a weight and cost save, but requires an increase in cross-sectional area of ~62%. Hence aluminium busbars need more volume for packaging. The highest conductivity is achieved by high purity aluminium (purity of 99.9 wt% Al and higher) in soft temper.
Copper sheets or rods are cut into the desired size and shape using advanced machinery, such as CNC (Computer Numerical Control) machines. Precision is crucial here; even minor inaccuracies can affect the performance of the final busbar. The cutting process ensures that each piece meets exact specifications, preparing it for further processing.
