The role of battery cut-off current
What cutoff voltage should be adopted for a given current using a …
$begingroup$ That makes sense: as the battery discharges, the internal resistance increases and conversely the resistance of the load decreases in order to mantain the current draw. Thus, there is a bigger drop over the internal resistance, hence a lower cutoff point related to a larger current. I wish there was a constant resistance load …

$begingroup$ According to Battery University: 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.

1. Introduction. As electric vehicles (EVs) grow in popularity, the demand for lithium-ion batteries (LIBs) simultaneously grows. This is largely due to their impressive energy density-to-weight ratios (measuring at 120–220 Wh kg −1 [1,2,3]), which allows them to outperform other battery technologies such as lead–acid batteries (PbAB) and nickel …
6. Controlling depth of discharge
Instead of merely cutting off loads when a low-voltage threshold has been reached, it takes into account the amount of current being drawn from the battery. When the current being drawn is high, the shut-down voltage might be 10V, for example; whereas if the current being drawn is a small one, the shut-down might be 11.5V.

batteries
In general the answer is no, there is no minimum supply current needed to stabilize the output of a battery. (Switching power supplies do have a minimum current.) Experimentally, a voltmeter across the battery terminals will have a typical input impedance of 10 MΩ, so it would draw only 0.3 µA of current at 4 V.
