I probably already know the answer to this but here goes.

 

 

a few months back i found a 5V router and wired an old USB cord to the power plug so i can use it Via USB powered.(5V)

 

i was wondering if could wire my tablet battery(2800mAh) to the cord i made a few months back to have a portable router.(which i have plans for) like possibly have it like a "Y" cable, that splits at 3 ends.?? and have it charge and discharge correctly?

 

I suspect No , but worth a shot.

The 5Volts DC will work, but the amperage needed is 2.5A.  2800mAh (milliampere-hour) is not the figure we need.

That's what i was worried about was the amperage :/

 

so i cant split the cord i already made one more direction so it can charge and discharge correctly?

 

this was my thinking:

 

grab the USB cord that powers the DIR-601, remove the elec. tape

twist the wires together that correspond to the usb cord with the tablet battery (polarity wise)

that way it can be USB or Tablet battery powered and have the option to charge the battery.

 

(the tablet battery has a tiny board at the top that the wires get soldered on to then those wires go to the tablet mobo)

 

What's that tiny board for?

The circuit inside the battery serves two purposes. One it monitors the battery temperature during charging and sends a signal to the micro controller based main charging system inside the Laptop to shutdown the charging process. Secondly it has an in built over load protector which protects the battery from dead shorts.

 

Here's the thing about amperage, it must meet a minimum amount.  In this case it is 2.5A.  You can't go below this, but you can have more amps than required.
