battery pack is removed from the system while under load, there is an opportunity for a damaging transient to occur. The battery pack should have sufficient capacitance to reduce transients or have something to clamp them. An even greater danger exists if there is a momentary short across the battery pack. The Li-ion safety protector may
The design of an efficient thermal management system for a lithium-ion battery pack hinges on a deep understanding of the cells'' thermal behavior. This understanding can be gained through theoretical or experimental methods. While the theoretical study of the cells using electrochemical and numerical methods requires expensive computing facilities and time, the
At 4:18 in this video (shown below), it shows that the circuit can be powered by the battery charger while it is charging the battery pack through the BMS. I feel like the current draw from the device would interfere with the charger''s CC/CV modes and battery state monitoring, causing incorrect battery charging, or insufficient power for the
The battery charger circuit is designed for 7.4V lithium battery pack (two 18650 in Series) which I commonly use in most robotics project but the circuit can be easily modified to fit in lower or slightly higher battery Packs like to build 3.7 lithium battery charger or 12v lithium ion battery Charger.

Lithium-ion (Li-ion) batteries have been widely implemented in Electric Vehicles (EVs) and other energy storage systems due to their high energy density, negligible memory effect, and low self-discharge rate , .To meet the requirements of the high power loads, hundreds of Li-ion batteries have to be connected in series or parallel as a battery pack .
You need to add protection(s) to avoid that the battery voltage goes negative. And/or you can add comparators to make the short circuit (preferably through a resistor) and disable the constant current circuit. R1 also dissipates quite some power (0.5W if it''s a 1 Ohm resistor @500mA, 0.25W for a 0.510 Ohm resistor).
