A 48v battery is fully charged at 54.6v. The low voltage cutoff is around 39v. It is best not to discharge more than 80% of the capacity for good cycle life. 80% DOD is around 43v depending on cell chemistry. Li-ion has a flat discharge curve. The voltage will drop from 54.6v down to 50v fairly quickly then level off.
The nominal voltage of a 48V battery typically stands around 51.2 volts during standard operation. This value indicates the average voltage when the battery is neither fully charged nor discharged. When the battery is fully charged, the voltage reaches different levels depending on the type: Lead-Acid: Around 54.6V. Lithium-Ion: Close to 58.4V.
For a 48V lead-acid battery, the open circuit voltage (OCV) shows a full charge at about 54.6V. As the charge decreases, the voltage drops to 45.44V, indicating near-empty status. This relationship helps you gauge remaining capacity. Here’s a brief list of key voltage levels for a 48V lead-acid battery:
Regular use of a 48V battery voltage chart can help prevent over-discharging, which can damage the battery. It also allows users to plan charging cycles more effectively. This simple yet powerful tool is essential for anyone using 48V battery systems in applications such as electric vehicles, solar energy storage, or industrial equipment.

To check your 48V battery, set the multimeter to the DC voltage setting. Connect the positive lead to the battery’s positive terminal and the negative lead to the negative terminal. For 48V batteries, you should see a voltage close to 48V when fully charged. A hydrometer can measure the specific gravity of the electrolyte in lead-acid batteries.

If you remove all loads from the battery and wait at least 30 minutes (up to 24 or more hours for more accuracy), you will see the voltage quickly fall to 53.2 to 54V. This is the "resting voltage" and is what is completely normal for a fully-charged LiFePO4 battery. So anytime you see people mention voltage like 56, 57 or 58V, they ...

48v battery voltages help please
Craig, there are two low voltage shutoffs in your ebike. The first is in your ebike controller, typically set at 40-42 volts (for a 48V bike). Look on the controller label to find it. The second is in the battery BMS, but this one operates at the cell level, with the minimum being 3.0V/cell, or 39V for a 48V battery which uses 13 series groups.
