Detailed description about the battery:
This is a new LiFePO4( Lithium Iron Phosphate)48V 20Ah battery for your
Electric Bicycles provided by A123 RC store. It is assembled by original A123
system20Ah prismatic cells under the configuration of 16S1P. It is a good
choice if you wanna keep a spare electric bike battery on hand to double your
range or as a replacement battery.
The material of this battery is LiFePO4 as mentioned before. LiFePO4 battery is the
safest and fastest growing battery system for electric bike/bicycle applications and
it offers high-energy density and light weight.
Features of LiFePO4
(1)Safe technology of LiFePO4 battery can protect the battery from catching fire or exploding.
(2)The LiFePO4 battery has over 2000 discharge cycles life
compared with lead acid battery which typically has only around 300 times.
(3)LiFePO4 battery has extremely low self discharge rate.
(4)LiFePO4 batteries is the most environmentally friendly battery.
(5)LiFePO4 is maintenance free.
The size of this battery is 250×220×170mm.
The weight of the battery is 9.58Kg.
We installed a 16S20A BMS in the battery which can protect it from over-charging
and over-discharging. Moreover the balance function of the BMS can balance
the performances of every series which is able to assure good performance of
the whole battery.
According to the above information, we can know that the max continuous current
of the battery is 20A. So this 48V20Ah liFePO4 battery is available for those e-bikes
whose Motor is right or below 960W. Normally it has an average range of 50-75km
per charge. Range may vary depending upon rider weight and terrain. The 48 volt Lithium Ion Battery is faster and has quicker acceleration and is better
at climbing hills than the 36 volt battery.
Features of Assembly Kits:
We use the newest A123 20ah assembly kits to make the battery pack. They are no need to drill holes or
do welding on the tabs, which makes it very easy to build or repair if faulty.
The charge plug of this battery is female Cannon connector and we normally left the
discharging wire there without any connectors. If you have any other requirements about
the connector, please let us know.
About charging, we suggest customer always use matchable proper LiFePO4 charger.
The standard charge current of the battery is 5-10A. You can fast charge it sometimes,
but we don’t suggest you use fast charger frequently. Because fast charging will do harm
to the battery’s longevity.
