For most lithium-ion batteries, 12V models typically discharge to around 10.0V to 10.5V, 24V batteries drop to approximately 20.0V to 21.0V, and 48V batteries reach around 40.0V to 42.0V. At What Voltage Is a Lithium-Ion Battery Considered Dead?
[pdf] For a lead-acid battery the value above the OCV is approximately 0.12 volts. This “adder” voltage will vary very slightly (+/- 0.02V) for different plate additives and construction but it is a very good rule of thumb.
[pdf] Generally, the discharge rate of lithium-ion batteries is recommended to be between 0.2C and 1C. Therefore, for a 100ah lithium battery, the discharge current is preferably between 20a-100a. Beyond this value, the current should be exceeded, which can be damaging to the battery.
