  Custom Battery Connector & Wire Design: What You Need to Specify

  Oct 16, 2026

  SHANGGUO TECHNOLOGY / BATTERY KNOWLEDGE Custom Battery Connector & Wire Design: What You Need to Specify OCTOBER 16, 2026 Connector type, wire length, pin configuration and electrical requirements can all affect how a custom battery pack integrates with your device. Here is what you should specify before battery production. QUICK OVERVIEW A battery pack is more than cells, voltage and capacity. The connector and wire assembly determine how the battery physically connects to the device, how current is delivered, and how easily the pack can be installed or replaced. For a custom battery project, these details should be defined early in the design process. IN THIS ARTICLE 01 / Connector Type 02 / Pin Number & Polarity 03 / Wire Length & Gauge 04 / Electrical Requirements...

  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 Much Does a Custom Battery Pack Cost? Key Factors That Affect Pricing

  Sep 23, 2026

  CUSTOM BATTERY GUIDE How Much Does a Custom Battery Pack Cost? Key Factors That Affect Custom Battery Pack Pricing Custom battery pack pricing depends on much more than voltage and capacity. Cell selection, battery chemistry, dimensions, BMS, connectors, housing, prototype development and production quantity can all affect the final cost. How Much Does a Custom Battery Pack Cost? When you start a custom battery project, one of the first questions is usually: How much does a custom battery pack cost? There is no single price for every custom battery pack. The final cost depends on the battery chemistry, cell selection, voltage, capacity, dimensions, connector, BMS, housing, customization requirements, prototype development and production quantity. What Determines Custom Battery Pack...

  Lithium Battery Pack Testing: What We Test Before Shipment

  Aug 30, 2026

  Introduction For a custom lithium battery pack, good design is only the beginning. Before a battery pack is delivered, it needs to be checked for electrical performance, BMS protection, charging and discharging behavior, dimensions, connections, and overall assembly quality. At Shangguo Battery, testing is an important part of our custom battery pack manufacturing process. Depending on the battery chemistry, application, specifications, and customer requirements, different tests may be performed to verify that the battery pack meets the defined performance and safety requirements. This article explains the key areas we evaluate before shipment.   1. Why Battery Pack Testing Matters A battery pack is more than a group of battery cells connected together. It may include cells, a BMS, co...

  Custom BMS for Lithium Battery Packs: A Guide to Battery Protection & Communication

  Aug 28, 2026

  Introduction A lithium battery pack is more than a group of battery cells connected together. For many devices, the Battery Management System (BMS) plays an important role in protecting the battery, monitoring operating conditions, managing cell performance, and communicating battery status with the host device. For custom battery packs, the BMS needs to match the battery chemistry, voltage, current, cell configuration, operating environment, and communication requirements of the application. A properly designed BMS helps create a battery solution that is safer, more reliable, and better integrated with the equipment it powers.   1. What Is a Battery Management System (BMS)? A Battery Management System, or BMS, is an electronic system designed to monitor and manage the operating condi...

  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...
