Current draw from Li-ion battery during short circuit
How much current is drawn from a short circuit of a Li-ion battery. You need protection circuitry such as a fuse to protect against that. Use a battery that can supply 10amps at a wide range of charge levels, and use a 10 amp fuse. Even better if the battery has it''s own BMS or charge/discharge limiter built in. A 5ah 2C pack would be

How does the BMS know how much current to draw from the charging
The battery can also draw lesser current based on its design. The upper limit to how much current you can push depends on the BMS model installed in the battery, and it''s a tradeoff between speed and longevity/size. They usually have overcurrent protection, and can cut charging if a higher than wanted current is detected. The BMS also

How does a fuse prevent battery overcharging/discharging?
$begingroup$ But it is still good to have a fuse in series with the battery pack to prevent fire (wires can catch fire when too much current flows through them) in case of short circuits and a current that becomes too large. Note that the fuse protects against currents getting too high. It does NOT protect the battery from over charging in any way. . Some extra advice:

What amount of current should I use to charge a 12V car battery?
There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.
batteries
No. A BMS is not a charger. If the pack has 2.7V per cell and you connect 4.2V per cell to BMS, only the series resistance of batteries and BMS are limiting the current and most likely current exceeds safe battery charging current and hopefully the BMS overcurrent protection shuts down the charging.
