Understanding Battery Bank with

Lithium iron phosphate (LiFePO4) batteries have revolutionized van life. Unlike lead-acid batteries, they can be discharged to 80-100% without damage, last 3,000-5,000 cycles, and weigh 70% less. They maintain consistent voltage throughout discharge and charge much faster. The built-in Battery Management System (BMS) protects against overcharging, overheating, and short circuits. While the upfront cost is higher, the cost per cycle is actually lower than lead-acid for full-time van dwellers.

Common Mistakes to Avoid

5. Overlooking Maintenance Requirements

Even 'maintenance-free' systems need occasional checks. Battery terminals corrode, connections loosen, and software updates may be needed. Build maintenance access into your design from the start.

2. Ignoring Future Expansion

Your needs today might not be your needs next year. Many builders wish they'd bought a slightly larger system to accommodate future upgrades - like adding more appliances or extending their travel season into winter.

3. Focusing Only on Upfront Cost

The cheapest option often becomes the most expensive. We've seen too many builders replace budget components within months. Quality matters, especially for items that are difficult to access after the build.
