The lowest permitted “low-voltage” power cut-off is 2.5V/cell. It is not advised to keep the battery at that level as self-discharge could bring the cell to its cut-off voltage, causing the battery to go into sleep mode. [pdf]

OCV is the voltage of the battery when it is not connected to any load or charger. A fully charged 12-volt battery should have an OCV of between 12.6 and 12.8 volts. If you measure the OCV of a battery and find that it is below this range, it may need to be charged or replaced. [pdf]

Here are the key differences between high voltage (HV) and low voltage (LV) energy storage batteries:Efficiency: HV batteries typically enhance overall system efficiency by reducing current, which lowers energy losses and conductor sizes1. LV batteries require higher currents to deliver the same power, potentially leading to increased energy losses1.Applications: HV batteries are often used in larger energy storage systems, such as grid storage and electric vehicles, while LV batteries are commonly found in smaller applications like home energy storage systems3.Cost: HV systems may have higher initial costs due to more complex components, but they can offer long-term savings through improved efficiency3. LV systems are generally less expensive upfront but may incur higher operational costs over time1. [pdf]
