48V Electric Golf Cart Battery Supercapacitor 100Ah 200Ah 300Ah
400Ah
Description
For applications that requires deep-cycle power, this is the
battery of choice. Use it in your personnel carrier, aerial lift,
electric vehicle, golf car, boat, RV, floor scrubber, or road sign.
The biggest innovations lie inside the battery, where we use
heavier grids, plates with higher density oxide and improved glass
mat envelope separators. The result? Longer life cycles and
superior cycle-life performance. The exterior features represent
powerful thinking as well. Engineers have designed a battery that
is as durable and user-friendly as possible. The heavy-gauge
polypropylene cases have been specially engineered to take a
pounding without damaging the cells. Twist-and-release vent caps
make removing caps a snap, and we’ve maximized convenience by
designing a new lifting system.

Comparing LiNMC to Lead Acid
Table 2 provides a brief comparison of lead acid to LiNMC on a pack
level. It should be noted that both chemistries have a wide range
of parameter values, so this table is only a simplified
representation of a very complex comparison.

Figure 1 (from Battery University) compares the specific energy of
lead, nickel- and lithium-based systems.
While NCA is the clear winner by storing more capacity than other
systems, this only applies to specific energy. In terms of specific
power and thermal stability, Li-manganese and Li-phosphate are
superior. Li-titanate may have low capacity but this chemistry
outlives most other secondary batteries in terms of life span. It
has also the best cold temperature performance. As we move towards
electric powertrains, safety and cycle life are becoming more
important than capacity alone.

lithium-based batteries
Lithium Iron Phosphate (LFP or LiFePO4) :
Lithium Iron Phosphate - LFP - LiFePO4-cell
Lithium Ferro Phosphate technology (also known as LFP or LiFePO4),
which appeared in 1996, is replacing other battery technologies
because of its technical advantages and very high level of safety.
Due to its high power density, this technology is used in
medium-power traction applications (robotics, AGV, E-mobility, last
mile delivery, etc.) or heavy-duty traction applications (marine
traction, industrial vehicles, etc.)
The long service life of the LFP and the possibility of deep
cycling make it possible to use LiFePO4 in energy storage
applications (stand-alone applications, Off-Grid systems,
self-consumption with battery) or stationary storage in general.
Major advantages of Lithium Iron Phosphate:
Very safe and secure technology (No Thermal Runaway)
Very low toxicity for environment (use of iron, graphite and
phosphate)
Calendar life > 10 ans
Cycle life : from 2000 to several thousand (see chart below)
Operational temperature range :up to 70°C
Very low internal resistance. Stability or even decline over the
cycles.
Constant power throughout the discharge range
Ease of recycling
Life-cycle ofLithium Iron Phosphate technology (LiFePO4)
Lithium Iron Phosphate technology is that which allows the greatest
number of charge / discharge cycles. That is why this technology is
mainly adopted in stationary energy storage systems
(self-consumption, Off-Grid, UPS, etc.) for applications requiring
long life.
The actual number of cycles that can be performed depends on
several factors:
Level of power in C-Rate
Depth of Discharge (DOD)
Operational environment : temperature, humidity, etc.
