About this product
Extended 12V Power for RV & Off-Grid Use
Built for users who need more runtime from a 12V system, the 12V 200Ah Bluetooth LiFePO₄ battery provides 2560Wh of nominal energy, 200A continuous discharge, Bluetooth monitoring, and Smart BMS protection. It is a practical high-capacity choice for RV, camper, solar, and off-grid power systems.
More Energy. Longer Runtime.
With 2560Wh of nominal energy, the 12V 200Ah battery gives RV and off-grid users more stored power for everyday electrical needs. More capacity means longer runtime between charges, making it well suited for multi-day travel, camping, and extended off-grid use.
Built for Demanding 12V Systems
With up to 200A continuous discharge, the 12V 200Ah battery is built to support compatible higher-demand 12V systems. When properly matched with wiring, circuit protection, and power equipment, it can supply everyday RV loads such as refrigeration, lighting, electronics, and other compatible devices.
Monitor Your Battery from Your Phone
Bluetooth monitoring gives you quick access to key battery information directly from your smartphone. Check SOC, voltage, current, charging and discharging status, and protection information without opening the battery compartment..
Flexible Charging for Your Setup
Designed for a 14.4V ± 0.2V LiFePO₄ charging profile, the 12V 200Ah battery can be integrated into properly configured RV and off-grid charging systems. Choose the charging method that fits your setup, including solar, DC-DC, or shore-power charging with compatible equipment.
Start with 200Ah. Expand When You Need More.
Start with a single 12V 200Ah battery and expand your energy system as your needs grow. Compatible batteries can be configured up to 4S4P, allowing parallel connections for more capacity or series connections for higher system voltage.
Plan Your Installation with Confidence
Before installation, check your available compartment space, terminal clearance, cable routing, and mounting method.

FAQs
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.
Its performance exceeded my expectations, and its standby time was long enough for me to use it for a long time
