Electric Golf Buggy Golf Car Golf Trolley Golf Cart Lithium Battery 6V 8V 12V 24V 48V
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.

The rules for use and storage of batteries
Protect from improper handling.
Do not insert with opposite polarity, follow the signs. If the batteries are inserted in reverse, can cause a short-circuit or charging.
Prevent short-circuiting. If possitive (+) and negative (-) battery terminals are connected, short-circuiting happens.
Before installing, clean the terminals of battery and the terminals facilities.
The LiFePO4 should be always mounted with the terminals facing upwards.
Do not heat excessively. – batteries operate at temperatures according to the specifications.
Do not weld the cells.
Do not disassemble. When open may be contact with different parts of the battery harmful.
Do not distort. Batteries should not be compressed, punctured or damaged in any way.
Do not dispose of in fire.
Do not expose to water or excessive humidity.
Keep away from children. Beyond their reach, it is necessary first of all to keep away batteries which can be swallowed. In addition, children should not be allowed replacement of batteries without adult supervision.
Do not incase or modify. Any modifying of the battery may cause block safety ventilation mechanism. Any adjustments should consult the dealer.
Unused batteries should be stored charged and keep them away from metal subjects, which can make short-circuiting the battery. Alreary unpackage units should not be mixed and stored with unused batteries.
Avoid extreme humidity (over 95%) High temperature or humidity may worsening of battery characteristics and / or corrosion of the surface.
Do not storage / expose the battery to direct sunlight, in places where they may be exposed to rain, excessive heat such as radiators or heaters.
Batteries stored in well-ventilated and dry environment, ideally enclosed in a protective case.
During storage, keep the temperature within the range according to the specifications of a particular article.
Do not mix with other materials.
Do not stack cardboard box with batteries. When stacking may cause deformation of the battery in the lower layers and the subsequent flow of electrolyte.
