Lithium battery output current is too large to cut off power
Li-ion BMS cuts voltage for no obvious reason
For many reasons. If the voltage source can''t handle it, it may hiccup and fail to output, or get damaged. If it does manage to charge the battery, 18V is too much for 4 cells and there is nothing to stop charging, except for the BMS overvoltage protection. If it works to cut off the cells from voltage supply. $endgroup$ –

To address this issue, we present the current limit estimate (CLE), which is determined using a robust electrochemical-thermal reduced order model, as a function of the pulse duration, depth of discharge, pre-set voltage cut-off and importantly the temperature.
Comprehensive Guide to Lithium-Ion Battery Discharge Curve …
Therefore, when lithium-ion batteries discharge at a high current, it is too late to supplement Li + from the electrolyte, and the polarization phenomenon will occur. Improving the conductivity of the electrolyte is the key factor to improve the high-current discharge capacity of lithium-ion batteries.
Understanding the limitations of lithium ion batteries at high rates
Charging lithium ion cells at high rates and/or low temperatures can be detrimental to both electrodes. At the graphite anode, there is a risk of lithium plating rather than intercalation, once the electrode voltage drops below 0 V vs. Li/Li +.
Overload is when the tool is being used (power OUT FROM the battery) and the current draw goes up too high (for example, when the bit is too large or the torque too consistently high). In these cases, a well-designed tool turns itself off to protect both the tool and battery. A good battery-tool system monitors both aspects of this energy usage.
I have a simple comparator circuit I was planning to use for a 2-cell Li battery. I''d like to cut the voltage off at around 2·2.8 V = 5.6 V. To accomplish this I have the circuit below, but just a little bit of noise in the battery voltage and it will cause my comparator (which drives a P-MOSFET) to oscillate between high and low output.

Li-ion cannot absorb overcharge. When fully charged, the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium and compromise safety. To minimize stress, keep the lithium-ion battery at the peak cut-off as short as possible. Once the charge is terminated, the battery voltage begins to drop.
