However, lithium-ion batteries can be damaged and do not benefit from trickle charging. Once a lithium-ion battery is fully charged, keeping it connected to a charger can lead to the plating of metallic lithium, which can compromise the battery’s safety and lifespan.
A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.
Now that you have your preferred gadget take a seat, and let’s explore the world of lithium-ion battery charging. Rechargeable power sources like lithium-ion batteries are quite popular because of their lightweight and high energy density. Lithium ions in these batteries travel back and forth between two electrodes when charged and discharged.
In fact, the internal charging mechanism of a lithium-ion battery is closely tied to the chemical reactions of the battery. Consequently, the chemical reaction mechanisms, such as internal potential, the polarization of the battery, and the alteration of lithium-ion concentration, have a significant role in the charging process.
Another research that employed a PC approach for charging lithium-ion batteries is described in , in which the lithium saturation is avoided by correctly selecting the parameters, allowing significantly higher rates of charging.
In their study, following a multi-module charger, a user-involved methodology with the leader-followers structure is developed to control the charging of a series-connected lithium-ion battery pack. In other words, they are exploiting a nominal model of battery cells.
Why is charging with Lithium batteries with a small load …
You cannot "over charge" the battery with this method (assuming of course the charger max voltage is 4.2 V per cell), but as you put it, you''re keeping the battery at max voltage for extended periods of time which reduces the life span.

Lithium battery charging best practices (How to & other tips)
Lithium batteries charge at 95% to 98% efficiency, which means that if 1000 watts of power is input to the battery, the battery retains 950 to 980 watts. Lithium batteries maintain this efficiency for their useful lifetime. Lead-Acid batteries, best case, charge at 80% efficiency when they are new. However, charging efficiency drops steeply for Lead-Acid batteries as they age, and less …
