Power tool batteries are wired in series - this is the configuration that needs active balancing. The voltage adds up (two 4.3V cells makes a 8.6V pack) and the current capacity is the same (two 1 Ah batteries makes a 1Ah battery). These can be combined - a 2S2P battery pack has 4 cells - two parallel sets in series.

If you suspect that your lithium battery is failing, it's best to replace it rather than continue to use it, as a failing battery can pose a safety risk. How Much Does It Cost To Repair A Lithium Battery Pack?
The following steps should be followed in order to reassemble the battery pack correctly: Ensure that all components of the lithium battery pack are present, including cells, wires, terminals, and case cover. Assemble the cells into their respective terminal connections.
Unlike disposable batteries, Li ion battery packs are rechargeable. Thus, any manufacturer can reuse lithium-ion batteries many times. This feature makes them cheaper and greener compared to single-use batteries. Lithium-ion battery packs have a longer life. Thus, they last longer compared to other types of rechargeable batteries.
Finally, after completing repairs on a lithium battery pack, disposing of spent cells properly is imperative; hazardous material laws must be followed at all times in order to ensure environmental protection and avoid legal repercussions.
