The Pecron WB12200 12V 200Ah Lithium Battery Delivers 2560Wh of Expandable Power For Reliable Home Backup And Off-Grid Adventures
The Pecron WB12200 Lithium 12V 200Ah Deep Cycle LiFePO4 Battery delivers serious, dependable power for off-grid, RV, marine, and backup power systems where reliability matters most.
Built with advanced LiFePO4 chemistry, this battery provides a full 200Ah of usable capacity at 12V while maintaining a stable voltage curve, even under heavy loads. Compared to traditional lead-acid batteries, it’s significantly lighter, charges faster, and delivers thousands more cycles—making it a smarter long-term investment for power-critical applications.
An integrated battery management system (BMS) protects against overcharging, over-discharging, short circuits, and temperature extremes, ensuring safe operation and long service life. The WB12200 is designed for deep-cycle use and supports parallel and series configurations, giving you the flexibility to scale your system as your power needs grow.
Whether you’re running an RV full-time, building an off-grid cabin system, powering marine electronics, or upgrading a solar battery bank, the Pecron WB12200 provides clean, efficient, and maintenance-free energy you can trust — day after day, cycle after cycle.

Pecron WB12200 Lithium Battery Features
This Battery Lasts Over 3500 Cycles for Years of Use
The WB12200 delivers more than 3500 charge cycles before reaching 80% capacity. This means you can use it daily for nearly a decade. Unlike lead-acid batteries that die after 300-500 cycles, this lithium battery saves you money by eliminating frequent replacements and disposal costs.
Expand Your Power Up to 40.96kWh by Adding More Batteries
Start with one battery and add more as your needs grow. Connect multiple WB12200 units together to build exactly the power system you want. Perfect for growing RV setups, expanding cabins, or increasing home backup capacity without buying everything upfront or replacing your existing battery.
Automatic Heating Lets You Charge Even in Freezing Cold Weather
Built-in heaters warm the battery automatically when temperatures drop below freezing. This means you can charge from solar panels during cold mornings or winter camping trips. Most lithium batteries cannot charge in freezing weather, but the WB12200 keeps working when you need it most in harsh conditions.
Smart App Control Shows Your Battery Status Right on Your Phone
Monitor your battery's charge level, temperature, and health through the smartphone app. Check how much power remains, see charging speed, and track system performance without guessing. This real-time information helps you plan your energy use, avoid surprises, and troubleshoot problems quickly and easily from anywhere.
This Battery Weighs Half as Much as Lead-Acid for Easy Moving
At just 48.5 pounds, the WB12200 delivers 2560Wh of power in a portable package. Traditional lead-acid batteries with similar capacity weigh over 120 pounds. The lighter weight makes installation easier, saves vehicle payload capacity, and lets you move the battery between applications without straining your back or needing help.
Advanced Safety System Protects Against Overcharge and Short Circuits
The built-in Battery Management System constantly watches for dangerous conditions. It prevents overcharging, blocks over-discharging, stops overcurrent problems, and shuts down automatically if a short circuit happens. The included 300A safety fuse adds extra protection. Your battery, devices, and investment stay safe through years of reliable operation.
Multiple Connection Options Work with Different Inverters and Solar Panels
Heavy-duty binding posts handle high-power connections up to 200A for large inverters. The XT90 connector provides quick 50A connections for solar panels and smaller devices. These flexible options let you build any power system you want. Switch between temporary portable setups and permanent installations without rewiring or buying adapters.
