How to Custom Lithium Battery Development:
How LiTech Power Builds the Perfect Battery Pack for Your Application
All devices need a good power source to work well. This includes electric boats, robots, home batteries, and portable medical devices.
A battery pack is one of the most important parts of the system.
It determines how efficiently the device works, how long it can operate, and how dependable it is in real use.
As a professional custom lithium battery manufacturer, LiTech Güç specializes in battery design and produces tailored battery solutions to meet precise technical requirements.
We have a factory in China, a branch office in Germany, and our own BMS factory: BesTech Power. With this setup, we provide high-quality, fully customized lithium battery packs to customers around the world.

Why Custom Lithium Battery Packs Are Needed
One battery cell usually isn’t enough to provide the voltage, capacity, or power most devices need.
Therefore, battery packs are built by connecting multiple cells in:
- Series (S) → to increase voltage.
- Parallel (P) → to increase capacity.
- Series and parallel combinations (S/P) → to achieve both
This flexible configuration allows us to deliver battery packs with precisely the required voltage, capacity, discharge rate, and high performance characteristics.

Key Information Required Before Designing a Custom Battery Pack
We first work with our customers to understand what they need and what their project goals are, then discuss more details of the project to custom lithium battery
Below is the information we typically confirm:
1. Required Voltage (V)
The system voltage determines how many cells need to be connected in series.
Common options include 12V, 24V, 36V, 48V, 60V, 72V, and fully customized levels. A wide range of choices is available.
2. rechargeable batteries Required Capacity (Ah or Wh)
Capacity decides how long the battery will last.
We use enough parallel cells so the battery lasts as long as you need and supplies the required energy.
3. Continuous & Peak Discharge Current
We need to know:
- Rated working current
- Peak current
- Motor/driver start-up current (if applicable)
This helps us select the right:
- Cell type
- Busbar design
- battery management systems BMS discharge rating
- Safety protection levels
4. lithium ions Battery Enclosure Type
We provide different housing options based on usage environment:
- PVC shrink film → lightweight, cost-effective, compact
- Plastic case → portable equipment, medical devices
- Metal / steel / aluminum case → outdoor, marine, industrial applications
- Custom housing based on your size limitation or mechanical drawing, custom lithium battery casing

5. Maximum Size Limitation
The physical dimensions you provide (L × W × H) help us determine:
- How many cells can fit
- Which cell format to use (18650, 21700, pouch, prismatic)
- Whether we need a developing custom metal enclosure or module design
6. Communication Protocol Requirements
To match your system, we support multiple BMS communication options:
- CANbus
- RS485
- UART
- SMBus
- Bluetooth monitoring (APP)
Our BMS factory, BesTech Power, ensures high reliability, fast customization, and stable communication performance.
7. Additional Functional Requirements
Depending on the operating environment, we can integrate:
- Bluetooth monitoring
- Self-heating system for low-temperature use
- Active or passive cell balancing
- High-IP waterproof design
- High-temperature protection
- Custom connectors and wiring harnesses
