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] Every lithium iron phosphate battery has a nominal voltage of 3.2V, with a charging voltage of 3.65V. The discharge cut-down voltage of LiFePO4 cells is 2.0V. Here is a 3.2V battery voltage chart. Thanks to its enhanced safety features, the 12V is the ideal voltage for home solar systems.
[pdf] A 12V inverter cannot run on a 24V battery. This setup may cause immediate failure and void the warranty. Always verify input specifications before connecting. For safe operation, use an inverter that matches the battery’s voltage rating.
