Lithium Polymer (Lipo) Battery Guide
To actually determine how many amps a battery can supply, multiply the battery pack''s Amp-Hour capacity by the C rating. An example of a 2000mAh battery pack at 10C: 2000mah / 1000 x 10C = 20 amps. Both capacity and C rating play an important role in determining the maximum discharge rating. Typical C ratings are 10C, 15C, 20C, 25C, …

Lithium-ion battery pack equalization based on charging voltage curves
Lithium-ion battery pack capacity directly determines the driving range and dynamic ability of electric vehicles (EVs). However, inconsistency issues occur and decrease the pack capacity due to internal and external reasons. In …
Maximum Cell Discharge Capability
4. Measuring Maximum Current – having estimated the maximum current it is good practice to check this data against the actual cell. It is advisable to approach this value rather than push the cell too far and damage it. All of these measurements are going to take time as the maxumum current is dependent on lots of parameters.
