  Custom Battery Pack Size & Shape: How to Design a Battery for Limited Space

  Oct 08, 2026

  BATTERY DESIGN GUIDE Custom Battery Pack Size & Shape: How to Design a Battery for Limited Space Learn how to design a custom battery pack for tight spaces, irregular battery compartments and demanding device requirements. Why Battery Size and Shape Matter For many electronic devices, the battery cannot simply be selected from a standard size. Portable medical equipment, industrial instruments, smart devices, handheld tools and other compact products often have limited internal space. A custom battery pack can be designed around the available space instead of forcing the device to accommodate a standard battery. Voltage, capacity, dimensions, shape, connector, wire length and protection functions can all be considered during battery design. 01 Start with the Available Spa...

  Li-Ion vs Li-Polymer vs Ni-MH: Which Battery Chemistry Is Right for Your Device?

  Sep 29, 2026

  BATTERY TECHNOLOGY GUIDE Li-Ion vs Li-Polymer vs Ni-MH: Which Battery Is Right for Your Device? Compare Li-Ion, Li-Polymer and Ni-MH rechargeable batteries and learn how to select the right chemistry for your custom battery pack. Choosing the Right Battery Chemistry Battery chemistry is one of the first decisions to make when developing a custom battery pack. Li-Ion, Li-Polymer and Ni-MH batteries all provide rechargeable power, but they have different characteristics in terms of energy density, voltage, size, weight, shape flexibility and application requirements. The right choice depends on your device design, required runtime, available installation space, voltage, capacity, weight requirements and operating environment. A battery manufacturer can also help evaluate the cell conf...

  How to Choose the Right Custom Battery Pack for Your Device

  Aug 24, 2026

  Introduction Choosing the right battery pack is an important step when developing or upgrading a battery-powered device. A suitable battery pack should not only provide enough power, but also fit the available space, meet the required runtime, communicate correctly with the device, and operate safely in its intended environment. For OEM and ODM projects, battery specifications are rarely one-size-fits-all. The right solution depends on the device, application, operating conditions, and electrical requirements. This guide explains the key factors to consider when selecting a custom battery pack for your device.   1. Define the Device's Power Requirements The first step is to understand how much power your device needs. Important parameters include:   Nominal voltage Operating vol...
