From refrigeration and lighting to entertainment and remote work, the BUKNUWO 314Ah battery supports a wide range of everyday RV power needs.

Smart Bluetooth Battery Monitoring

Connect to the BUKNUWO Bluetooth app to monitor battery state of charge, voltage, current, power, temperature, and individual cell voltage data. Check key battery information directly from your smartphone while within Bluetooth range.

Smart Protection Built In

The integrated 200A Smart BMS monitors battery operation and provides essential electrical and temperature protection for your 12V energy storage system.

Expand Your Energy System

The BUKNUWO 12V 314Ah LiFePO₄ battery supports configurations up to 4S4P. A full 16-battery system provides a nominal voltage of 51.2V, total capacity of 1256Ah, and approximately 64.31kWh of energy storage. Each battery operates with its own independent BMS.

FAQs

Yes, you can connect the battery to a compatible 12V inverter. However, its 200A Smart BMS limits continuous discharge to 200A, equivalent to approximately 2560W at the nominal battery voltage. A single battery cannot continuously deliver the full 3000W inverter output. Actual AC power capacity is lower after accounting for inverter efficiency and battery voltage. Always check the inverter's startup surge, wiring, and protection requirements.

The battery provides approximately 4019Wh of nominal energy storage. Runtime depends on your appliances, power consumption, inverter efficiency, and operating conditions. For example, a constant 100W AC load could theoretically run for approximately 34 hours assuming 85% overall usable efficiency. Actual runtime varies.

Use a compatible LiFePO4 charger with a recommended charging voltage of 14.4V ± 0.2V. The recommended charging current is 20–50A. BUKNUWO 14.6V 10A and 20A LiFePO4 chargers may also be used if their charging profiles are compatible with the battery. A 20A charger will charge the battery faster than a 10A charger.

Yes. This model supports up to 4S4P configurations. Four batteries in series provide 51.2V 314Ah, while a full 4S4P configuration provides 51.2V 1256Ah and approximately 64.31kWh of nominal energy. Use matching batteries and follow the correct wiring and protection instructions. Each battery has an independent BMS; Bluetooth monitoring does not provide automatic state-of-charge synchronization between batteries.

Download the BUKNUWO app, enable Bluetooth and the required phone permissions, and search for your battery in the app while standing close to it. Select the matching battery to view its status. Do not pair the battery directly through your phone's system Bluetooth settings. If the battery is not detected, check app permissions and whether another phone is already connected.

Yes. The battery can be charged through a compatible MPPT or other suitable solar charge controller configured for a 12.8V LiFePO4 battery. Use the recommended charging voltage and ensure the controller's output is suitable for the battery. Do not connect solar panels directly to the battery without a suitable charge controller.

The specified charging temperature range is 0°C to 45°C (32°F to 113°F), and the discharge temperature range is -20°C to 60°C (-4°F to 140°F). Do not charge the battery below 0°C (32°F). Temperature protection helps protect the battery from operation outside its permitted range.

The battery measures 15.16 × 7.59 × 9.84 inches (L × W × H) and weighs approximately 58.42 lbs. Measure your battery compartment before purchasing, and allow additional space for terminals, wiring, ventilation, and secure mounting.

I got a 314Ah battery. I knew I wanted to a Li battery, when my brand new trailer battery went dead running the 12v refrigerator..
I picked buknuwo because the battery was easy switch. I just charged my solar controller setting and dropped in
The battery. I know I can run the refrigerator for 72 hours. I love buknuwo thank you Jade jiang

The BUKNUWO 12V 100Ah LiFePO4 battery makes sense for a camping setup focused on everyday essentials rather than power-hungry appliances. LED lights, a small fan and phone charging are the kinds of loads I would plan around, with refrigerator use depending on its actual energy consumption.

Bluetooth monitoring is a useful feature because it makes checking battery status more convenient. Still, I would keep an eye on daily consumption instead of assuming that 100Ah will cover an entire weekend.

The main consideration is how often charging is available. For modest loads and regular recharging, this capacity looks like a practical choice. For longer stays, more equipment or uncertain solar charging, I would consider a larger battery to leave more reserve.

The 12v 100Ah battery meets my basic camping needs, and the Bluetooth function allows me to monitor the battery's level and status in real time. If traveling long distances or using additional appliances, I would consider the 150Ah or 314Ah models. I believe they won't disappoint me, and I highly recommend them.
