A battery with low internal resistance delivers high current on demand. High resistance causes the battery to heat up and the voltage to drop.
Industry Why is charging with Lithium batteries with a small load dangerous?
If your charger outputs 1 A in CC mode, and has a 500 mA constant current load connected, then 500 mA goes to battery and 500 mA to the load. So the battery will also charge slower because only half the current goes into it. But floating a lithium ion battery at 4.2 V indefinitely is EXACTLY what the charger is supposed to avoid doing
Industry How can I determine LI-ion battery charge while varying the load?
Every battery is built to drop the voltage when you draw a larger current, this is why automotive batteries have a nominal voltage of 12V under high load current and normal voltage of 14.4V. In order to check the battery voltage you have to stop the load and charging circuits, wait until the battery voltage settles and then measure it.

Can a battery have voltage but no current?
Yes, a battery can have voltage but no current. This happens in an open circuit. Here, the battery shows voltage, but no load is connected to draw current. Voltage measures the potential difference, while current indicates the flow of electric charge. Thus, a voltage source can exist without current under these conditions.
