    4KW LiFePO4 Deep Cycle Golf Cart Battery Fast Charge / Discharge With BMS

    48V 4KW 3.7KW 3KW 3.5KW 2.4KW Lithium ion LiFePO4 Golf Cart Battery Pack with BMS


    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 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.
