AGM (Absorbent Glass Mat) and Lithium batteries each have their advantages for 4WD use. AGM batteries are robust, cost-effective, and perform well in various conditions, making them a solid choice for traditional setups. Lithium batteries, while more expensive, offer higher energy density, faster recharging, and longer lifespan, making them ideal for high-performance or off-grid applications. The best choice depends on your specific needs and budget.
