Charging 3P pack of 18650 batteries using a single TP4056, and protection standards
There is no conflicts with any examples.


parallel operation is to boost currents by sharing
series to charge 1 card to 1 battery from a higher voltage.
arrays to combine both above
You can use as many cards in parallel as long as do not exceed the source current limit.  
Each card has a Rprog to set say for 0.5A or 1A and USB charger hubs often support 2.4A per port such as 6 ganged ports with 60W max which are low cost.(eg Blackweb)
However charging and discharging simultaneously requires independent Ibat and Ichg sensing so battery current can be cutoff while charging the load directly.
this is to prevent cooking the battery at 4.2V CHRG drives  the load draws more the 5%CC used for battery cutoff.
The TP4056 uses a high side FET switch to regulate battery current 
the DW01 balancer  disconnects  charge discharge FETs on the low side 
so you need to consider how to regulate both output ports ( Bat. and load) independently and have flow control from both voltage sources. (Charger and Bat.) 


So draw a block diagram / wiring schematic and define all interfaces specs for voltage and current and see what needs to be done with parallel load and battery charge to prevent the above failure when current sharing.

I.load + I.bat &lt; I.charge.max.
If > > I.charge.max, reduce I.bat then 
if still > Icharge, disconnect load

Consider;


priority is given to external load unless faulted or overload on hard start.   
charge service to battery is 2nd priority.    
Gang as many batteries in parallel as long as you know charger capacity
5V Molex has more current capacity than USB ports
loads are responsible for protecting / regulating themselves 
supplies are responsible for protecting themselves
chargers are assumed dumb otherwise and just responsible for regulating voltage @ some I max.
ICL’s (NTC) at Digikey may be used as a soft start 
PTC’s may be used a fuses
limit the time spent with 4.2V on Battery to reduce aging is another option for cutoff with some timer in minutes
