Lithium-ion Forklift Batteries
Lithium Storage provides a fully customized smart lithium-ion battery adaptable solution for forklifts, including every brand, model, shape, and weight to replace old lead acid battery technology. Our team of engineers can also design bespoke solutions for new product development. Our fully featured customizable solution can retrofit forklift brands including Toyota, Crown, Hyundai, HELI, LINDE, Yale, Mitsubishi, NICHIYU, and Jungheinrich. Our SMART FLT solution improves operational working hours available with a faster charging time and longer life.
Forklift battery Types Description
Lead acid battery (Web cell）
The most common type of forklift battery is a lead acid battery, which is also called a wet cell battery. The main advantage of lead acid batteries is their price compared to other types of batteries. The lead acid battery also has several negative aspects. First, wet cell batteries need to be maintained regularly to keep the performance; as a result, a special watering system needs to be equipped and there is a trained person for this activity. Second, the long charging time is the biggest negative aspect of lead-acid batteries, typically 8 hours. This leads to the need for more space for meeting charging needs.
With correct maintenance and charging procedures, most Wet Cell batteries will last up to five years or 1,500 charging cycles.
Gel Cell Lead-Acid (Gel cell)
A gel cell battery is similar to a lead acid battery, but silica is added to create a gel electrolyte mixture. A special watering system is not required because the gel cell battery is sealed. This means less maintenance than lead acid batteries. The disadvantage of a gel cell battery is the slow charging, and you cannot leave it for free charging, because the gel electrolyte will be destroyed if you leave it charging after charging is completed.
Absorbed Glass Mat (AGM)
Absorbed Glass Mat (AGM) is a special glass mat for passing electrolytes between battery plates, which is another type of sealed lead acid battery. The construction of AMG batteries allows working without any watering maintenance like wet cell batteries. The main negative aspect of the AGM battery is the low cycle life. The cycle of life and performance of AMG batteries can be harmed by each charge. It is recommended to charge the battery when discharge is only above 50%, the expected cycle life is around 1300cycles.
Lithium-ion battery
Smart LFT lithium-ion battery has multiple benefits in comparison to other types of forklift batteries. They are maintenance-free.Therefore a special watering system is not required. As well as the fast-charging performance is the main advantage, only 2-3hours to fully charge batteries. Additionally, the deep charging or discharging will not harm the cycle life of the batteries because of no memory characteristic of lithium-ion batteries. The most important advantage of lithium-ion batteries is to increase the cycle life up to reach 3000cycles.

What is our design thought about forklifts lithium batteries?
our-design-thought-about-forklifts-lithium-batteries.jpg
Based on forklift trucks being manufactured in various nonstandard configurations, we select outer box and inner box combination solutions to design our forklift lithium batteries, inter-box for batteries, outer-box for dimension, and additional weight. The advantage of this design is to maximize adapting to more forklift brands and models by using the same inner box. We investigate the battery requirements of many forklift brands on the market, in particular in the dimension and capacity, and summarize 3 model of standard forklift battery products (not including additional weight). Our standard products 25.6V205AH, 41.2V410Ah, and 83.2V410Ah can meet around 80% of forklift requirements in lithium batteries upgraded from lead acid batteries.For saving shipping costs to the international market, Lithium Storage suggests that customers can purchase inner boxes from us, and add weight and outer boxes locally.

Lithium-ion Batteries for Commercial Vehicle
The Flexi Pack is developed by Lithium Storage for electric-powered mobility, especially for commercial vehicles, such as trucks, electric buses, and special vehicles powered by batteries. Flexi Pack has two sizes, Flexi pack C, and Flexi pack D. Flexi Pack C&D is our standard pack designed based on prismatic lithium iron phosphate cells LFP205Ah, LFP230Ah, LFP280Ah, and LFP302Ah. Fixed dimensions with multiple battery combinations in type and quantity can enable multiple configurable system applications.
Why choose the Flexi battery pack for your EVs?
The Flexi battery pack is our standard pack and is a mass production battery and assembly in the commercial vehicle projects in China's local market, therefore the quality has been verified through a series of Chinese National Standard for electric vehicles application and actual operation. Additionally, the Flexi pack has been certificated by MSDS and UN38.3, so will not have any international transportation issues. Compared with a customized battery pack, the Flexi pack has a competitive price advantage and also saves the certification and development costs by being a ready-to-go proven product.
Flexi Pack is active cooled.

Lithium Battery Module
Lithium Storage provides standard lithium battery modules and customization of lithium-ion battery modules based on LFP/NCM prismatic lithium cells, including the structure of the banding module and frame welding module. The high structural strength of the frame welding module meets harsh vehicle operating conditions, and the high flexibility of the banding module meets a wide range of dimension requirements.
Do lithium batteries need to be compressed in assembly?
According to the characteristics of aluminum shell batteries, during the life cycle, there will be slightly natural swelling at the center of the large side surface. During assembly of the cells, the customer needs to use a clamping plate to clamp the cells tightly before putting them into the pack enclosure. The recommended clamping force is 150kgf-300kgf for NCM cells and 200kgf-500kgf for LFP cells. (The above is for reference only. For reference to clamping force value, please refer to cell specification for details)
During the cycling of the battery, the cell's internal swell force will increase gradually. At the EOL (end of life) the max internal swell force of the NCM cell will be 2500kgf and the LFP cell will be 2000kgf. The clamping device needs to be strong enough against EOL internal swell force.

Lithium Battery Cell
A lithium battery cell is the smallest unit of a battery. There are several types of classification of lithium battery cells from shape, chemistry of positive materials, and battery C ratings.
Shape: Cylinder, Pouch, Prismatic
Lithium Storage focuses on the prismatic type of lithium battery cells.
Chemistry of positive materials: lithium iron phosphate (LFP), lithium nickel cobalt aluminum oxide（NCA）, lithium nickel manganese cobalt oxide (NCM) lithium manganese oxide (LMO) and Lithium tantalite oxide (LTO)
Lithium Storage concentrates on the LFP and NCM chemistry both types of lithium battery cells.
Battery C ratings: energy cells and power cells
Energy cells are designed to deliver constant charge and discharge current in the long-term period, generally continuous C rating less than 1~2C. Power cells are designed to support charge and discharge current at a high rate for meeting the load application requirement.
Lithium Storage has both energy cells and power cells.
What Are The Advantages Of Lithium Storage Lithium Batteries
