Voltage Reference
Use this reference to understand common battery voltage options and how they are typically used across RV, marine, golf cart, solar, backup power, and energy storage systems.
12V / 12.8V
Commonly used for RV house power, marine electronics, trolling motors, portable power setups, and small backup systems.
- Typical LiFePO4 nominal voltage: 12.8V
- Common charger reference: 14.6V LiFePO4 charger
- Check BMS current rating before powering high-load devices
24V / 25.6V
Used in larger trolling motors, off-grid setups, and systems that need lower current than a 12V configuration.
- Typical LiFePO4 nominal voltage: 25.6V
- Common charger reference: 29.2V LiFePO4 charger
- Confirm inverter and controller voltage range
36V
Often used in 36V golf carts and some electric mobility systems.
- Verify golf cart controller compatibility
- Use a charger designed for 36V lithium systems
- Check battery tray size and cable layout
48V
Commonly used in golf carts, higher-power electric systems, and some inverter-based applications.
- Verify controller, charger, and battery communication needs
- Check continuous discharge rating against system load
- Confirm physical fit before purchase
51.2V
Common in LiFePO4 energy storage systems for home, commercial, solar, and off-grid applications.
- Typical LiFePO4 nominal voltage: 51.2V
- Often used with compatible hybrid inverters
- Check CAN / RS485 communication requirements if applicable
Compatibility Matters
Voltage must match your equipment. A battery with the wrong voltage can damage devices or prevent the system from working properly.
- Match battery voltage to your system voltage
- Use the correct charger profile
- Confirm BMS limits, wiring, and installation requirements

Common Voltage Options
12V / 12.8V systems are commonly used for RV house power, marine electronics, trolling motors, camping setups, and small backup systems.
24V / 25.6V systems are often used when a system needs more power with lower current than a 12V setup.
36V systems are commonly found in some golf carts, trolling motors, and electric mobility applications.
48V systems are used in many golf carts, higher-power electric systems, and some inverter-based applications.
51.2V LiFePO4 systems are commonly used for home energy storage, solar storage, commercial backup, and larger off-grid power systems.
Why Voltage Matters
Voltage affects battery compatibility, charger selection, wiring current, inverter matching, and system performance.
Using the wrong voltage can prevent the system from working properly and may damage connected equipment. Always match the battery voltage to your system requirements.
Charger Reference
Different battery voltages require different charging voltages. For example, a 12V LiFePO4 battery commonly uses a 14.6V LiFePO4 charger, while higher-voltage systems require chargers designed for their specific voltage range.
Always use a charger that matches both the battery chemistry and system voltage.
Important Notes
This reference is for general battery selection guidance only. Actual system requirements may vary depending on your equipment, charger, inverter, controller, wiring, and installation setup.
Before purchasing or installing a battery, confirm the required system voltage, compatible charging profile, BMS requirements, and physical installation space.
