100Ah LiFePO4 Lithium
Batteries

Here’s a quick rundown of why Aluminum Encased Lithium Batteries
Perform Better:
A typical aluminum encased battery that has better heat
dissipation will start out with a higher cycle life. Dependent upon the size of the cell the
expectant charger cycle life of a smaller LifePO4 cell can be as much as 4000
charge cycles and follow the same trajectory of the plastic prismatic cell
shown below. The simple fact is that if
you have an application where you want a long life, like for solar storage, and
you do not discharge the cells below their nominal 3.2 voltage you will have a
cell that will probably outlive you.
Depth of discharge has a very profound effect on a lithium battery’s
life.
What is the Life Expectancy of the Aluminum Batteries?
- Factor 1: Depth of
Discharge…Percentage of Capacity Used Per Cycle.
- DOD, short for the
Depth of Discharge, is used to describe how deeply the battery is discharged.
If we say a battery is 100% fully charged, it means the DOD of this battery is
0%, If we say the battery have delivered 30% of its energy, here are 70% energy
reserved, we say the DOD of this battery is 30%.
- Factor 2: Discharge Rate, The AMPS Divided by
the Capacity
- To Read the Chart
Above, Here are Some Examples
A. All Numbers are at a 1C
Discharge Rate, Which is Aggressive…
B. At a 90% Depth of
Discharge, Our Batteries Will Provide 2400 Cycle to 80%
State-of-Original-Capacity (SOIC)
C. At a 10% Depth of
Discharge (Say, Engine Starting) Our Batteries Will Provide 35,000 Cycles Until
80% SOIC. Beyond 35,000 Cycles the Battery is Still Functioning But Gradually
Losing Capacity, but not Performance
Conclusion: By recharging a lithium battery more frequently, thus
reducing the DOD (depth of discharge), the battery cycle life is Increased.
Solar is very often a beneficial method to reduce DOD and increase life!

Connect your new 100Ah EV, Lithium, LiFePO4, LFP Aluminum Shell Battery
pack together in parallel (neg to neg and pos to pos) for 24 hours before
connecting in series and charging. This gives your new batteries time to balance
their voltages to a degree.
It is also strongly suggested that you use a BMS or
balancing system for your new 100Ah EV, Lithium, LiFePO4, LFP Aluminum Shell
Battery pack.
Always use caution when working with high
voltages.
