Big current will go from the 0V end of the battery to the other end (20V, 30V, 40V, 50V, depends on pack size). In this "direction" you need to consider arrangement and thickness of the nickel strips, and also the placement of the negative and positive wire of the entire pack can matter. Optimally each cell has even load.

Easy battery pack soldering method . The biggest problem with assembling custom battery packs has always been that the stainless steel terminals and cases of cells are very difficult to solder; there are special solders and fluxes available, but they typically also require higher heat, which has greater potential to damage the cells; there has been a lot of work devoted to developing

Desoldered the battery again, and it seems still dead, just like the original battery.. Momentarily connecting pack+ to the positive of the li-ion cells (i.e bypassing the protection board mosfets - not sure if that is a good idea tho) brings the pack back to life (can draw current from it) - solder it back into the speaker, speaker flashes red for a bit, and then it''s dead in the same way.

Aging can also cause the battery pack to swell. As it ages, the battery pack can cause an elevation in temperatures. Example of a swollen lithium battery pack.
Battery pack with cell leakage due to outgassing. Users who have electrolyte leakage should take the necessary precautions to not come in contact with the liquid or the electrolyte residue. The electronics that come in contact with the electrolyte leakage can also short circuit. You may notice that the battery enclosure is large and bulging.
Using the incorrect charger for the lithium battery pack can also cause a range of problems. Most battery pack chargers for lithium-ion batteries are designed to prevent overcharging. However, using the wrong charger can cause overcharging or over voltage of the lithium battery pack as well as swelling.
This problem is caused by the lithium battery swelling. Swelling can occur for a number of reasons. For example, moisture may have intruded into the battery pack. Overcharging is also a common reason for battery pack swelling. Aging can also cause the battery pack to swell. As it ages, the battery pack can cause an elevation in temperatures.
During certain lithium-ion battery failures, the pack will create a hissing noise. When this occurs, take the device to a safe place where there is nothing combustible and try to remove the battery pack. At this time, gases may vent from the battery pack or it may ignite or explode.
Most of the problems with battery packs will be prevented by the BMS. Other problems such as small shorts or aging will simply cause the battery to stop working. Yet, consumers should be aware of the dangers that can occur. Issues such as leakage and thermal runaway are the most dangerous.
