500-1000 Times Electric Bicycle Battery Pack 10 - 30Ah Or Customized
How to look after and store lithium ion batteries for electric bikes
There are a few basic but important tips you can follow in order to
keep your battery in tip top condition:
Batteries have an optimum operating temperature - around room
temperature. So charge the battery indoors in very cold weather,
and keep it indoors until the last second to keep the cells warm.
Keep the battery indoors in colder weather and avoid storing them
in direct sunlight.
If you are riding all year round and often in subzero temperatures
it could be worth getting a battery cover. Fahrer make a variety of
covers from neoprene and cordura – here’s a more in depth look at
them.
All batteries will be damaged if persistently over-charged or
over-discharged. Use the correct charger for your battery (in
particular never use one that wasn’t specifically made for your
battery). If you buy a good quality e-bike in the first place they
are more likely to have reliable BMS (battery management system)
units in the battery which also helps prevent over charging and
discharging.
Don’t leave a lithium battery connected after it has achieved full
charge.
Be wary of cheaper batteries with suspiciously high claims for
battery life and the number of charge cycles they will last – it
may have been set close to the limits for under and over charging
which could lead to premature failure.
Avoid vibration and shock to a battery through rough handling or
careless treatment as this can lead to a shortened life too.

Lithium ion
Li-ion batteries have excellent energy density (amount of energy
stored per their physical weight). They also have excellent
longevity meaning that they can be discharged and recharged or
cycled many times and still maintain their storage capacity.
Lithium-ion actually refers to may battery chemistries that involve the lithium ion. Here is a short list below:
Lithium maganese oxide (LiMN2O4); aka: IMR, LMO, Li-maganese
Lithium maganese nickel (LiNiMnCoO2); aka INR, NMC
Lithium nicked cobalt aluminum oxide (LiNiCoAlO2); aka NCA,
Li-aluminum
Lithium nickel cobalt oxide (LiCoO2); aka NCO
Lithium cobalt oxide (LiCoO2); aka ICR, LCO, Li-cobalt
Lithium iron phosphate (LiFePO4); aka IFR, LFP, LI-phosphate
Each of these battery chemistries represents a trade-off between
safety, longevity, capacity, and current output.
