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] In a battery with a balancing circuit, the circuit simply balances the voltages of the individual cells in the battery with hardware when the battery approaches 100% SOC – the industry standard for lithium iron phosphate is to balance above a cell voltage of 3.6-volts.
[pdf] It has a shelf-life of up to 10 years, a high running voltage, a flat discharge voltage curve, low impedance which enables better performance at low temperatures, and advanced safety features like over current protection.
