There has been a growing demand for custom lithium polymer batteries from more and more product vendors, however, most companies do not have battery engineers, battery designers, or other capabilities. As a result, lithium battery manufacturers come to help customize batteries. Small factories are unable to provide customization services due to limited R&D and production capacity, as well as the higher requirements for small sample quantities. In this article, you will learn how to find a reliable & professional custom battery manufacturer for your custom battery needs.
A new battery model is customized based on the specific needs of customers as part of technology content. In comparison to the traditional cylindrical batteries, such as the 18650, 38120, etc., there are several factors that need to be considered: battery factory production processes, materials control, and a wealth of experience. In general, when customizing a battery, we will take into account the five major user requirements.
1. Personalized based on capacity
According to the product's power consumption, calculate whether the battery's capacity can meet the user's demand for endurance time.
2. Customized based on the shape
Batteries can be customized in terms of size and shape. It can be shaped in various forms, including round, rectangle, curved, triangle, etc., along with its different dimensions, thickness, width, and length.
3. Customizable by C-Rate
C-Rate (multiplier) requirements will vary for certain special products, such as RC toys (RC cars, RC boats), drones, electronic cigarettes (vapes), jump starters for cars, medical devices, and so on. In order to meet the demand for fast charging or high burst power, high current charging and discharging performance of the battery is the most critical consideration.
4. Customization by voltage
As lithium batteries are generally charged to 4.2V, many product designers are using 4.35V high-voltage lithium polymer batteries (LiHV) to make their batteries more durable and energy dense. In this case, the battery engineers and product designers must cooperate, depending on the appliance and PCB scheme.
5. Customization based on temperature
It is best to use lithium batteries at 25°C, and their general operating temperatures are between -20°C and 50°C. The capacity of lithium batteries will decrease sharply in a high and low-temperature environment, which may affect their life or even prevent them from functioning normally. Therefore, high-temperature lithium batteries or low-temperature lithium batteries are needed that are specially designed. AllrunBattery has extensive experience developing low-temperature battery products, the lowest can reach -45 °C, for special electricity industries.
What can I do to customize my battery?
A. A design for an existing product
Battery customization is required if you already have a product design, space size, and size fixed.
Focus on these points -- Manufacturing technology: how much energy density; Mold opening fee (cost); Can you provide matching boards.
B. The product has not been designed
Currently, you do not have a product design, but need to customize a battery, which involves programming experience. You should find a professional battery manufacturer with a strong R & D team and reference cases available.
Focus on these points -- Could they meet their own needs if the battery factory offered evaluation services? such as battery life, the weight of the battery, battery shape, maximum product size, and so on.
It's necessary to measure and judge the battery's performance in many aspects, such as multiplier, voltage, and internal resistance. Its performance is reflected in the product experience through the combination of a battery and protection plate (BMS/PCM), which are placed in application products. In order to tailor a battery to the needs of the product users, all aspects of the battery data must be considered at this time. We must not only provide customized factory qualifications and basic battery parameters, but also understand the product application and service targets in order to provide a customized battery.
