The short answer is, yes. Here are some reasons to consider: - Lithium batteries have a much longer lifespan (about 10-20yrs) as opposed to lead acid (about 2-5yrs) and Big Battery offers a 10yr warranty. - Lithium delivers the same amount of power throughout the entire discharge cycle, but lead acid batteries start out strong, but the power decreases throughout the discharge cycle. - The price is about the same for comparable range, however you can increase the range by adding more batteries. The only downside is that you will need to purchase a new charger. - The weight savings is huge! You can drop about 275lbs by with a comparable lithium setup. - Plus they are maintenance free!
