A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Such critical conditions include: Over-charge: is when the battery is charged over the allowed maximum capacity. High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature ...
Li-ion batteries contain a protection circuit that shields the battery against abuse. This important safeguard also turns the battery off and makes it unusable if over-discharged. Slipping into sleep mode can happen when storing a Li-ion pack in a discharged state for any length of time as self-discharge would gradually deplete the remaining charge.
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3.6V Li-ion cells in series, also known as 4S, to produce 14.4V nominal. In comparison, a six-cell lead acid string with 2V/cell will generate 12V, and four alkaline with 1.5V/cell will give 6V.

The lithium battery that was used at the time as a ½ AA cell with wire leads on it. The original battery holder was removed and .156 KK series Molex header pins were mounted on the board. Matching trifurcon crimp pins were placed on the battery and it was mounted on the board. This worked quite well for almost 15 years.
(Many also include software for the PC that can automatically shut it down safely, if you aren''t nearby at the time.) It might be possible to use the battery power of a UPS to run a laptop or cell phone for a much longer …
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 ...
It''s costly hardware that you must buy in addition to the battery pack. How To Choose and Use a Management System for Your Battery. Using a battery without a management system can be dangerous. Without it, your battery has no protection against overcharging or overheating. A BMS is also necessary for continuous monitoring.
I use the laptop without the battery now with no problem. However, on a Window''s update, it is best to have it in for the restart after updating. [note: F1 is the bypass key]
If the lithium battery pack does not need a protection circuit board, for some users who do not pay attention to the daily protection of the battery, the service life of the battery will be greatly reduced, and more failure …
Lithium ion or polymer cells need to be protected from under or over discharging, which can be really bad. This is done by a battery management system/board, or BMS. It''s a device that combines battery protection for multiple cell batteries like we are building. It''s called a battery management system or BMS for short.
