How Does Battery Management System (BMS) Protect Battery
When the battery reaches its maximum safe voltage, the BMS will turn off the charging circuit to prevent further charging. ... The BMS prevents overcharging by limiting the charging voltage or current when the battery reaches its maximum safe voltage limit.

How Many Amps is a 18650 Battery?
The maximum current a battery can safely provide is dictated by its discharge rate, which is linked to its ampere capacity. Discharge Rate Specifications For a typical 18650 battery, the discharge rate could range between 15 to 30 amps. High-drain batteries intended for demanding applications can even exceed this range. Relation to …
Why current does not instantly reach maximum value in an
When we study circuits with only resistors, (I mean ideal circuits only), then we assume that the current reaches its maximum value instantly as soon as the switch is on $dots$. You might assume this but it is only an approximation.
batteries
If you draw current very slowly from the battery, then up to a point you''ll get the maximum energy out of the battery -- but above that point, the battery''s self-discharge current (which I''ve modeled with R2) dominates.

How long does it take the current to drop to half its initial value? How long does it take before the energy stored in the inductor is reduced to (1.0 %) of its maximum value? Strategy. The current in the inductor will now decrease as the resistor dissipates this energy. Therefore, the current falls as an exponential decay.
