How do I know if my LiFePO4 battery is bad?
To determine if a LiFePO4 battery is bad, look for these signs:
- Reduced capacity and shorter runtime.
- Low voltage readings consistently below the expected level.
- Difficulty charging or failure to reach a full charge.
- Physical damage, swelling, or bulging of the battery.
- Excessive heat during use or charging.
- Error messages or warnings indicating a battery issue.
If you notice any of these signs, consider having the battery tested or replaced by a professional.
What is the nominal voltage of a LiFePO4 battery?
The nominal voltage of a LiFePO4 battery is typically 3.2 volts per cell. In a 12-volt LiFePO4 battery pack, there are usually four cells connected in series, resulting in a nominal voltage of 12.8 volts. It’s important to note that the nominal voltage may vary slightly depending on the specific battery manufacturer and configuration.
