Is draining a Li-Ion to 2.5 V harmful to a Li-ion cell?
$begingroup$ Yep -- for Li-Ion batteries there are three important protections: OCP (over-current protection), UVP (under-voltage protection) and OVP (over-voltage protection). OCP applies in both directions, charge and discharge, and the value at which it trips (especially charge) varies with temperature -- it''s a bad idea to charge a Li …
Lithium Smart Battery Manual
Absorption voltage: 14.2V for a 12.8V lithium battery (28.4V / 56.8V for a 24V or 48V system Absorption time: 2 hours. We recommend a minimum absorption time of 2 hours per month for lightly cycled systems, such as backup or UPS applications and 4 to 8 hours per month for more heavily cycled (off-grid or ESS) systems.
Battery charging voltage too high...problem? | Android Central
So I suspect its max voltage is set to 4.3, which then would have a nominal 3.8v or so rather than the most seen 3.7v. and sure the battery''s nominal voltage is 3.8 printed on the battery. So, I think this isn''t an issue but intended. am not a specialist in the field so not quite sure what chemical differences are causing this..
How does Internal Resistance affect Performance ...
These pulses push the voltage towards the end-of-discharge line, resulting in a premature cut-off. As seen in the chart, the internal resistance governs much of the runtime. ...

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. ... That is, the result of polarization makes the end voltage of the battery discharge lower than the electromotive potential of the battery, which is higher than the ...
BU-402: What Is C-rate?
A 1C discharge rate would deliver the battery''s rated capacity in 1 hour. A 2C discharge rate means it will discharge twice as fast (30 minutes). A 1C discharge rate on a 1.6 Ah battery means a discharge current of 1.6 A. A 2C rate would mean a discharge current of 3.2 A.
