Ebike battery, what you should know?

What kinds of ebike batteries are there?

When you ride a recent newly ebike, you’ll get some kind of lithium-ion battery. Old, used e bikes can contain other chemicals; The earliest electric bikes used very heavy lead-acid batteries, then came nickel-cadmium and nickel-metal hydride batteries, both of which are lighter and can still retain some capacity for shorter runs.

Although with the extra expense and complexity, good quality, good capacity lithium-ion batteries are often the most practical choice; It will give you the best range, reliability and life. 

What is the best ebike battery?

It is hard to judge that. A good battery has many variables, and what’s best for you may not be what’s best for me. Even so, a good battery will not perform well if it is not well cared for.

A battery pack consists of a single battery “cell”. There are columnar cells and columnar cells . Each type of battery has a different shape The most commonly used battery in an e bike battery pack is the 18650.When it comes to batteries,, there is a strong correlation between price and quality. You really don’t want to compromise on quality, though, because you’re going to have to pay for it eventually.

Li-ion has several variants of cell chemistry. The most common and popular lithium batteries for ebikes are Nickel Manganese Cobalt (NMC), Lithium Cobalt Oxide (LCO), and Lithium Iron Phosphate (LFP). When selecting a cell here are some indicators:

A. Specific Energy: it will affect the range of your battery.

B. Specific Power: how the battery handles high load scenariosl.

C. Safety: does the chemistry have a history of high in-field failures.

While choosing battery cathode material chemicals, there are trade-offs, and both NMC and LFP are good choices that offer the best value for performance, price and safety.

Some factors that also affect the battery lifespan:

A. Environmental conditions: temperature during charging & discharging

B. Charge rate: the speed at which the battery is charged

C. Charge voltage: The voltage to which the battery is charged

D. Discharge depth (DOD): indicates the voltage to which the battery discharges

How to appropriately charge your e bike battery?

A. Batteries have an optimal operating temperature room temperature. So charging your battery in cold weather should keep it indoors until the last second to keep it warm. In cold weather, keep the battery indoors, away from direct sunlight. If you ride year-round and often in sub-zero temperatures, it’s worth buying a battery cover.

B. All batteries will be damaged if persistently over-charged or over-discharged. Use the right charger (made by the manufacturer specifically for your battery). If you purchase a high quality ebike at first, they are more stable with a reliable BMS(battery management System) unit in the battery, which also helps prevent overcharging and discharging. 

Don’t make a lithium battery stay connected after it has achieved full charge.

C. Be wary of cheaper batteries, as their battery life and charging cycle can be set near the limits of too low and too low charging, which can lead to premature failure.

D.  Avoid vibration and shock through rough handling or careless handling, as this can also lead to shortened life.

E. Try to avoid storage of lithium batteries, which degrade over time whether they are used or not. If you do need to store lithium batteries for several months, check the discharge status recommended by the manufacturer.

Conclusion

To sum up, there are many factors to consider when choosing the best battery for your ebike, and of course there is no one size fits all. But if I decide to buy an ebike battery, here’s what I will do :LFP or NMC, charge current and speed, avoid storing it or charging it at extreme temperatures, and keep the battery at 30% if you’re not going to use it for a while, and the most convenient way is to resort to professional mauafacturer as Maxworld, to give you better solutions.
