You need to have physical protection in place as well. One bad fall or dodgy landing and you risk puncturing a cell, which will rapidly cause thermal runaway as adjacent cells short into the damaged cell. Good luck disconnecting a flaming battery pack from your board before it takes the whole thing up. Lithium-ion batteries are really no joke.

The power for EVs comes from batteries, which are typically a combination of three distinct units nestled inside one another — individual cells, groups of cells contained within a module, and the battery pack. The cells are the core of the battery as they concentrate the substances that are used to produce electrical energy.

Battery protection unit The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on. BMS IC
Looked closer at @mr_hyde corroded BMBs. While they were all in the hump + front 2-3 rows of the pack. 1 BMB (module #9) was different than the rest. @mr_hyde car''s module #8 was also the worst corrosion and the one with 1V lower brick that disabled the car. This provided the clue of what is happening and why Tesla has changed the pack design.
The type of housing depends on where the battery pack will be located inside the device and if it is intended to be accessed by the end-user or a technician.

Whether you should store solar batteries inside or outside depends on several factors, including the type of battery, your local climate, available space, and safety considerations. Here is a more detailed explanation of these key factors: Battery Type. The type of solar battery you have or plan to install can influence its storage location.
The only difference between the two is the extra protective circuit board mounted on the battery cell. If you have some unprotected 18650 battery cells, but you want to use them individually, then you should protect them. It provides 40-watt of power and solders the protection circuit to the 18650 battery easily without damaging the circuit
To efficiently evacuate gases generated during TR, degassing valves are installed in the battery pack housing. The type and number of valves are designed based on the cell''s gas mass flow. To prevent ignition of the gas/air mixture outside the battery pack, large smoldering particles must be kept inside, for example, by using filters.
B- is the negative end of the battery, P+ is the positive end of the battery pack, P- is the negative end of the battery pack, VSS is the ground of the battery protection management IC, the negative end of the battery, and VSS and the source of Q1 are connected together. Before the PCM board is operational, Q1, Q2 are both off. Application Note

A: 99.99% of those adapters are physical mount adapters with straight wires inside from terminal to terminal. They do not provide battery protection, they have no circuitry inside aside from some resistors to trick the tool into thinking it has a genuine battery connected to it, so you will most likely overdischarge the battery and kill it.
The charger will be on the mother baord. the protector and the Eprom which counts the usage, will be inside the battery. Thus removing the battery when you have AC power will stop counting the battery life. But that will be counted in the mother board and will be updated the next time you insert the battery.

Overcurrent Protection. Detection circuitry inside the BMS continuously monitors the current flowing through the BMS discharge MOSFETs. If this current rises above a certain threshold, the BMS switches off the MOSFETs and effectively removes the battery pack''s electrical connection to the outside world. Undervoltage Protection
These design considerations encompass various factors ranging from the specific requirements of the battery pack to customization options that can enhance the functionality of the protection board. Battery Pack Specifications: Size: The physical dimensions of the battery pack influence the form factor and layout of the protection board.
When charging, the protection board will monitor the voltage of each string of the battery pack in real-time, as long as one of the strings reaches the overcharge protection value (the default charging voltage is 3.75V±0.05V), the protection board will cut off the power supply, and the entire set of lithium batteries will stop charging.
You can customize the protection requirements of various additional functions for your lithium battery, such as communication function, SOC calculation, SOH estimation, warning function, recording function, display function, etc. Tritek
Battery PCB protection boards are essential components of a lithium-ion battery pack. It protects the battery cells from overcharging, over-discharging, and short-circuiting. The board monitors the battery's charge levels and temperature and sends signals when limits are reached.
The battery cells can now receive a charge from a charger. Some devices may pull out too much of a charge in too fast of a short time span. To protect the battery cell and MOS tube, the protection board enacts discharge protection to the cell, turning off the pins and disconnecting the switch tubes.
Protection boards for lithium batteries offer monitoring protection. Low-voltage lithium batteries require a protection board. When using high-voltage lithium batteries, a battery management system (BMS) is typically chosen since these systems contain more functions for monitoring the state of the battery pack.
The main function of the protection board is to monitor the state of charge (SoC), temperature, voltage, current, and state of health (SoH) of the battery pack. The MOS is controlled by the control IC. The MOS is always turned on during normal functions.
You can also obtain custom-built protection boards with your custom battery packs. This arrangement is ideal since the battery manufacturer will have a greater understanding of the protection needs of the custom pack that they design for the customer. So, the protection board would cater to these design requirements.
Highly recommended for older lithium ion batteries. Protects against, over-charge, over-discharge, short-circuiting, and potentially other things.
