this is my first time asked on stack exchange, please bear bare with me. Anyway, I created portable monitor using multiple TP4056 as battery charger & protection circuit. But I'm not sure it's safe or not.
this is the wiring diagram : 
why I wired this way? Apparently the monitor needs more than 5 Watt, and using 1 TP4056 can't give enough power. (the monitor needs 12 volt). So far my solution works, but I worried about the safety.
what I'm asking is this solution safe?
Thank you
edit 2: To power up 12 volt monitor, I stepped up the output from TP 4056 (from around 3-4 volt) using XL6009 module to 12 volt. As you can see, the module located under the batteries.
