Understanding Electrical System on

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.
