Most battery protection circuits use a chip (eg. Seiko) with a pair of external MOSFETs for charge and discharge voltage protection. Also overcurrent protection with PTCs. Specific product recommendations are off-topic, but you can look at Seiko's line-up and compare.
Lithium batteries have the advantage of high energy density. However, they require careful handling. This article discusses important safety and protection considerations when using a lithium battery, introduces some common battery protection ICs, and briefly outlines selection of important components in battery protection circuits.

Fig. 1 is a block diagram of circuitry in a typical Li-ion battery pack. It shows an example of a safety protection circuit for the Li-ion cells and a gas gauge (capacity measuring device). The safety circuitry includes a Li-ion protector that controls back-to-back FET switches. These switches can be
The DW01A is a lithium-ion/polymer battery protection IC designed to protect single-cell lithium-ion/polymer batteries from overcharging, overdischarging, and short circuits. In this project, we'll guide you through designing a battery protection circuit using the DW01A, ensuring the safe and reliable operation of your battery-powered devices.
You can buy a batch of ready-to-go protection circuit modules, or just use the protection circuit laid out on the TP4056 module PCB. You can also accumulate a decent stock of protection circuits by taking them out of single-cell batteries whenever the cell puffs up or dies – take caution not to puncture the cell while you do it, please.
Considerations in choosing battery protection ICs Two important parameters in battery ICs are overvoltage threshold and undervoltage threshold. These numbers are the voltage levels at their limit; the IC will cut the cell out of circuit if the cell is being overcharged or over-discharged.
