can you make a lithium battery pack with protected batteries
As others have previously stated in the comments, there is no inherent issue with using a battery protection IC unless the overarching mechanical design of your enclosure is very poor. A more fragile lithium-ion battery with a ribbon cable will still break if somebody rips it out with extreme force. A battery will still catch fire if you puncture it. The majority of purely electrical issues faced with the PCB can be overcome with a battery protection circuit, but you still need to make sure the mechanical design of what you are creating is sufficient for its desired application.
