$begingroup$ Because the intrinsic diode is in parallel with the FET. If you have two batteries connected the two FETs are turned on and there is a balancing current path available. The FETs short out the intrinsic diodes. So you have to put diodes in series with the battery to control battery to battery current. $endgroup$ –

That said, a lithium battery is super nice to have since it is small, strong and lightweight! However, if your regulator and rectifier are outdated, they can overload the lithium battery which can lead to overheating or even an explosion. How to prevent this?
The battery pack''s total cost is obtained by summing the costs of the LIBs (Panasonic 18650 LIB at $2.5 each). Assuming the EV has 16 battery packs, each consisting of 74S6P (444 LIBs) configuration, similar to the Tesla Model S. It is evident that the total cost of the BTMS proposed in this study is lower, offering better economic benefits.

Lithium batteries can indeed be connected in parallel, and this method is commonly used to achieve higher capacity and extend the runtime of a battery system. By connecting two or more lithium batteries with the same voltage in parallel, the resulting battery pack retains the same nominal voltage but boasts a higher Ah capacity.
According to the parallel principle, the current of the main circuit is equal to the sum of the currents of the parallel branches. Therefore, a parallel lithium battery pack with “n” parallel batteries achieves the same charging efficiency as a single battery, with the charging current being the sum of the individual battery currents.
The second type of rechargeable lithium battery is called a lithium ion battery, which has a negative terminal that consists of a carbon-based material, usually graphite, or another type of alloy or material that permits interrelation, i.e. storage, of lithium in the structure.
Batteries 1–4 in the series lithium battery pack correspond to the four lithium batteries shown in Figure 8. The charged charge SOC, voltage and current collection in the battery information acquisition board correspond to SOC, voltage and current modules shown in Figure 8.
Parallel lithium batteries have many advantages, including increased capacity, enhanced power output, and improved overall performance. When multiple batteries are connected in parallel, their individual ampere-hour (Ah) capacities add up, resulting in a higher total capacity.
Today, Li-ion batteries have completely taken over the computer and mobile phone battery markets, though portable NiMH batteries are expected to remain on the market as a low-cost alternative to lithium batteries.
