Both the BUKNUWO 24V 100Ah Standard and Smart Bluetooth batteries use LiFePO4 technology and provide the same 25.6V nominal voltage, 100Ah rated capacity, and 2560Wh nominal energy.Both versions support up to 100A continuous discharge and include built-in Battery Management System (BMS) protection against overcharging, over-discharging, overcurrent, short circuits, and temperature-related conditions.

The main difference is battery monitoring.

The Smart Bluetooth version allows you to connect through the BUKNUWO app to view supported battery information, including voltage, charging and discharging current, battery status, and protection alerts.

The Standard version does not include Bluetooth monitoring, making it a straightforward option for compatible 24V power systems that do not require app-based monitoring.

Choose the Smart Bluetooth version if you prefer convenient battery monitoring from your phone. Choose the Standard version if you need reliable 24V energy storage without Bluetooth functionality.

No. A 24V battery cannot directly replace a 12V battery in a system designed only for 12V operation.

The BUKNUWO 24V 100Ah battery has a nominal voltage of 25.6V and is designed for compatible 24V electrical systems.Connecting this battery directly to equipment designed exclusively for 12V may damage the connected devices.Before upgrading from a 12V system to a 24V system, make sure your inverter, charger, solar charge controller, and other electrical components support the correct voltage.

If your existing system uses two compatible 12.8V 100Ah batteries connected in series to create a 25.6V battery bank, a single BUKNUWO 25.6V 100Ah battery may offer a simpler alternative with fewer inter-battery connections.Both configurations provide 2560Wh of nominal energy.Always verify your complete electrical system before making the replacement.

Use a charger specifically designed for 24V (25.6V nominal) LiFePO4 batteries.The charger must provide a lithium-compatible charging profile and meet the battery's specified charging voltage and current requirements.
Important charging requirements:Use a compatible 24V LiFePO4 charger.

Do not use a 12V or 14.6V battery charger.Avoid lead-acid-only charging profiles that are incompatible with LiFePO4 batteries.Make sure the charger meets the battery's voltage and current requirements.Do not charge the battery when low-temperature charging protection is active.If you are using a solar charging system or an RV shore-power charger, confirm that its charging profile can be configured for your 24V LiFePO4 battery.Charging voltage must be verified against the current production-batch specifications before use.

Yes. Under the current proposed 2S4P configuration, up to four matching BUKNUWO 24V 100Ah batteries can be connected in parallel to increase total battery capacity.When connected correctly in parallel, the nominal system voltage remains 51.2V, while the total rated capacity and nominal energy increase.

Important installation requirements:Use matching batteries of the same approved model, capacity, and chemistry. Check that battery voltages and states of charge are appropriately matched before connecting them.Use correctly sized cables, appropriate circuit protection, and a balanced connection arrangement according to the approved installation instructions.Do not mix Standard and Bluetooth batteries in the same bank unless BUKNUWO has specifically approved the combination.

Important: Parallel expansion must follow the final connection limits approved for your battery model and production batch.

No. Under the current 1S4P configuration guidance for this product, series connections are not supported.

The BUKNUWO 24V 100Ah battery is intended for compatible 24V systems.Connecting two batteries in series would increase the nominal voltage to 51.2V, but this configuration must not be used unless the battery manufacturer explicitly approves series operation for the exact model and production batch.

Unauthorized series connections may cause BMS protection issues, battery imbalance, equipment incompatibility, or damage.If you need a 48V battery system, we recommend choosing a battery specifically designed and approved for a 48V application.For questions about system expansion, contact BUKNUWO Support before purchasing or connecting additional batteries.

The BUKNUWO 24V 100Ah battery can be used with a compatible 24V inverter, provided the inverter's electrical requirements remain within the battery's operating limits.The battery is rated for 100A maximum continuous discharge.

When selecting an inverter, check the following:

• Input Voltage: The inverter must support the battery's 24V LiFePO4 operating voltage range.
• Continuous Power Demand: The inverter's DC input current at your expected loads must stay within the battery's 100A continuous discharge rating.
• Surge Current: Some equipment, including motors, refrigerators, and compressors, requires higher power when starting.
• Battery Protection: Inverter startup surge or excessive current may activate the battery's BMS protection.
• Cables and Circuit Protection: Use correctly sized cables, fuses, and disconnects suitable for the electrical system.

A larger inverter does not automatically mean more usable power from the battery.We recommend checking your inverter's model, continuous power consumption, and startup surge specifications before installation.If you're unsure whether your inverter is compatible, contact BUKNUWO Support with the inverter model and connected equipment details.

Yes. The BUKNUWO 24V 100Ah LiFePO4 battery can store energy from a compatible solar charging system.However, solar panels should not be connected directly to the battery without suitable charging regulation.

A typical system includes:

Solar Panels → MPPT Solar Charge Controller → 24V LiFePO4 Battery → Compatible DC Loads or Inverter

The solar charge controller must support a 24V LiFePO4 battery system and provide the correct charging voltage and current settings.

Before connecting your solar panels, verify:

• The solar charge controller supports 24V lithium batteries.
• The charging profile is compatible with LiFePO4 chemistry.
• The charging voltage and current meet the battery specifications.
• Solar panel voltage and power are within the controller's supported limits.
• The system includes appropriate electrical protection.

The battery's 2560Wh nominal energy can be used to estimate your storage requirements, but actual solar charging performance depends on available sunlight, panel output, controller efficiency, and battery conditions.For best results, use a properly configured MPPT solar charge controller designed for your complete system.

Yes, the BUKNUWO 24V 100Ah battery includes low-temperature charging protection. However, it does not include a self-heating function.

The built-in BMS monitors battery temperature and helps prevent charging when the battery becomes too cold.The product specification lists a low-temperature charging protection threshold of approximately 0°C (32°F), with a specified protection tolerance.When low-temperature charging protection is activated, the BMS may restrict charging until the battery temperature returns to an acceptable range.

Low-temperature protection and self-heating are different features:

• Low-Temperature Protection: Helps prevent charging under excessively cold battery conditions.
• Self-Heating: Uses a heating system to warm the battery before charging. This model does not include that function.

For cold-weather RV, cabin, or off-grid use, install the battery in an appropriate protected environment and follow the recommended charging conditions.Do not attempt to force charging while low-temperature protection is active.
