Do I need LiFePO4 or Lithium Manganese Chemistry?
Last Reviewed: Mon, 27/Mar/2017
Let's keep this short and simple. ElectricRider offers two types of lithium battery chemistries, Lithium Iron Phosphate (LiFePO4) and Lithium Manganese (LiMn). Both chemistries offer the same great performance, and cost is very similar......so what's the difference?
- Size/Weight: If you're looking for the smallest and lightest weight battery to power your ebike, you'll want to look at the Lithium Manganese batteries. While all lithium batteries are much smaller/lighter than the old Sealed Lead Acid batteries, ElectricRider's Lithium Manganese batteries are only 60% of the size/weight of Lithium Iron Phosphate (LiFePO4). For example, a 48V 20AH LiFePO4 battery weighs 20lbs while the lithium manganese version weighs only 12lbs! If you don't have much space, or simply want to keep your project as light as possible, Lithium Manganese is the right choice for you.
- Cycle-Life: The number of times you can recharge a lithium battery is also a major factor when it comes to cost, and with Lithium Batteries there's always a trade-off. You now know that Lithium Manganese is smaller/lighter than LiFePO4, and there's a good reason. Lithium Manganese is generally rated for 800-1000 recharge cycles while LiFePO4 is rated for 1500-2000 recharge cycles. So if cycle-life or cost effectiveness is more important to you than the size/weight of your battery, LiFePO4 is the right choice for you.
