Hi everybody,
Could someone help me with this bac to basics trick which should allow me to connect an LED to the leads which connect to the battery charger when my robot docks so, when charging current is running through, the LED lights up?
I wish to do this without using any controller so no ADC port, no HIGH/LOW digital port, just an LED and whatever resistor / diode I may use in order to see that the current is flowing.

So when the robot docks, the LED would light up.
Thank you,

These charge over the thick cable.
There the balancer cable is used for measuring.
Then you have to remove the rechargeable battery.
The loading of Lipo is very sensitive.
You must not use any consumers.
This can end dangerous.
Please do not experiment with the battery.
Just remember the charging time.
The charging time is always almost the same.
What you could do is put an led across the positive and negative on the robot side, if its the right voltage, and with a resistor which I haven't calculated the value for. Then whenever the robot is plugged in, the led on the robot would light up. Doesn't use the Ez-b at all.
Only issue is if the battery stops charging, the led will get all the current if the charger doesn't stop.
Consumers, also an LED must not be used in the charging process.
This is extremely dangerous with Lipo accumulators.
After charging you can test the battery with a checker or Lipo beeper.
Does not cost much and works quickly and easily over the balancerkabel.
This is a Lipobeeper.
This is my favortite checker. Small and safe as Key chain.
Now if you keep a load on a lithium batterie with a charging tension at nominal value + PCB, you're not taking much of a risk. In my case I even add to these precautionary conditions the usage of a smart charger, + an automatic extinguisher + sprinklers in the apppartment + rental insurance... are u all reassured? Lol
Now I would really like to know how you make variate an LED's status with the intensity (amps) of a current
