What is the maximum current which can pass in a Li_ion battery?
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C.. …

What Is C-rate? How to read battery discharge curves?
Battery capacity is typically measured using a battery analyzer, which discharges the battery at a controlled current while monitoring the time it takes to reach the end-of-discharge voltage. The end-of-discharge voltages vary for different types of batteries: approximately 1.75V/cell for lead-acid batteries, 1.0V/cell for NiCd/NiMH …
How to calculate how much current can lithium battery provide?
Maximum discharge current : 1C. That means that it is rated to provide 250mA of current. As always, voltage can be raised by putting cells in series (but watch out for balancing issues), and current can be raised by putting cells in parallel. If both must be raised then a full array of cells must be used.

For example, a constant discharge current of 1 C (5 A) can be drawn from a 5 Ah battery for 1 hour. For the same battery a discharge current of 0.1 C (500 mA) can be withdrawn from the battery for 10 hours. For a given cell type the behavior of cells of different capacities with the same C ratio value is similar.
