TP4056 module parallel output
The cutoff voltage is a trade-off between maximum current capability and battery under-voltage protection, at high currents (which is your case)  the battery voltage can drop down to 2.5V even the battery is not over-discharged but this wasn't your question

There is nothing that forbids you to use this configuration, I actually used-it for a two batteries / two  TP4056 configuration.
