Lithium Polymer (LiPo) is the best type of Lithium-Ion battery for an electric bike. They have the potential to perform better than other types of Lithium-Ion batteries. In addition, they can look great on your bike.
Batteries are one of the most important and expensive components of an electric bike. A poor choice of battery will literally stop you in your tracks. Fortunately, any Lithium-Ion battery is likely to out perform older battery technologies.
The technology inside Li-Ion batteries is developing fast. Longevity, safety and capacity continue to improve at a steady rate. At the same time, new Lithium-based battery technologies are still emerging.
When choosing a Li-Ion it is worth buying a high-quality brand. Higher quality batteries will give your bike significantly greater range and power. They are also more durable and safer.
When choosing the best type of Lithium-Ion battery for an electric bike you need to consider the conditions you expect to encounter.
The best type of Lithium-Ion battery for an electric bike
- Lithium Nickel Manganese Cobalt Oxide (NMC) batteries deliver high power in a light, small package. It’s one of the newer eBike battery technologies and is gaining popularity due to the amount of energy that is packed into a small, light-weight package. Tesla electric cars use NMC batteries. LiPo batteries may use Nickel Manganese Cobalt Oxide.
Charge Cycles: 300-700
Specific energy: 205 Wh/Kg
Energy density: 580 Wh/L
- Lithium Manganese Oxide (LiMn2O4) batteries are slightly bigger and heavier than NMC batteries. They perform better in extreme temperatures and are the safest type of lithium-ion batteries.
Charge Cycles: 300–700
Specific energy: 100–150 Wh/Kg
Energy density: 420 Wh/L
- Lithium Iron Phosphate (LiFe of LiFePO4) are widely used in eBikes and have a longer lifespan than any other Li-ion battery. However, they are larger and heavier than NMC or LiMn204. Furthermore, lower discharge rates make them less suitable for high power electric bicycles.
Charge cycles: 2,000
Specific energy: 90–130 Wh/Kg
Energy density: 333 Wh/L
- Lithium-Ion with Polymer For comparison. Li-Po batteries can use the chemical compositions above.
Charge cycles: 300-400
Specific energy: 100–265 Wh/kg
Energy density 250–730 Wh/L
