Monitoring is in the battery, actual cutoff is done by the tool. Battery measures voltage of all cells and when any cell goes below 2.0V (for 18650 packs) or 2.5V (for 6ah, 9ah and high-output batteries), the battery signals the tool to stop. Most batteries have no way of cutting power. 12ah may be able to cut power, but I''m not sure.

Usually we don''t discharge RC batteries that far because at 3.3V - 3.0V you have less than 5% of the battery capacity remaining and the voltage will drop rapidly under load so you can quickly lose power completely. It also helps the battery lifetime to not discharge all the way to 2.5V.
