Why LiFePO4?
Of all the lithium options available, there are several reasons why LiFePO4 has been selected as the ideal lithium technology for replacement of AGM DEEP CYCLE. The main reasons come down to its favourable characteristics when looking at the main applications where AGM DEEP CYCLE currently exist. These include:
Weight Comparison:
LifePO4 is one third weight of AGM DEEP CYCLE
Weight has a large bearing on many applications, especially where towing or speed in involved, such and caravan and boating. Other applications including portable lighting and camera applications where the batteries need to be carried.
Greater Life Cycle:
Comparison
Benefits
The greater cycle life means that the extra upfront cost of a LiFePO4 battery is more than made up for over the life use of the battery. If being used daily, an AGM will need to be replaced approx. 6 times before the LiFePO4 needs replacing.
Flat Discharge Curve:
Comparison
Benefits
This feature is little known but is a strong advantage and it gives multiple benefits. With the flat discharge curve of LiFePO4, the terminal voltage holds above 12V for up to 85-90% capacity usage. Because of this, less amps are required in order to supply the same amount of power (P=VxA) and therefore the more efficient use of the capacity leads to longer runtime. The user will also not notice the slowing down of the device (golf cart for example) earlier.
Along with this the effect of Peukert’s law is much less significant with lithium than that of AGM. This results in having available a large percentage of the capacity of the battery no matter what the discharge rate. At 1C (or 100A discharge for 100AH battery) the LiFePO4 option will still give you 100AH vs only 50AH for AGM.
Increased Use of Capacity:
Comparison
Benefits
The increased use of the available capacity means the user can either obtain up to 60% more runtime from the same capacity option in LiFePO4, or alternatively opt for a smaller capacity LiFePO4 battery while still achieving the same runtime as the larger capacity AGM.
Greater Charge Efficiency:
Comparison
Benefits
Another strong benefit in many applications. Due to the lower internal resistance among other factors, LiFePO4 can accept charge at a much great rate than AGM. This allows them to be charged and ready to use much faster, leading to many benefits.
Low Self Discharge Rate:
Comparison
Benefits
This feature is a big one for the recreational vehicles which may only be used for a couple of months a year before going into storage for the rest of the year such as caravans, boats, motorcycles and Jet Skis etc. Along with this point, LiFePO4 doesn’t calcify and so even after being left for extended periods of time, the battery is less likely to be permanently damaged. A LiFePO4 battery is not harmed by not being left in storage in a fully charged state.
