Our brand-new supplies of Battery PCB are expertly finished and constructed from premium materials.
We have put a lot of effort into making this the best product currently available.
Your digital device needs the proper Battery PCB. Please read this entire page for all the details you require.
Battery PCB By Feature
Lithium-ion batteries can use this. These boards have components such as switches, ICs, MOS, and capacitors.
This product is typically used in chargers, which are classified as medium to small devices with 3.7V. These mini-circuit boards can be easily modified depending on design specs.
Battery PCBs are designed to work with lithium batteries. Ideally, batteries made of lithium polymer cannot be overcharged or undercharged.
We guarantee the removal of the excess capacitance in a rigid PCB that controls batteries. This is crucial for the current flow.
Our Rigid-Flex PCB for batteries follows a set protocol. For your safety, the majority are UL 94 V-0 flame-retardant rated.
What is a Battery PCB?
Batter Circuit Board, Battery Protection Circuit Board, and Battery Printed Circuit Board:
They are all names used to describe the same product: a circuit board for a battery.
So why would a battery need a circuit board?
This part controls the battery’s power so that it won’t unintentionally overcharge, discharge, or short-circuit.
A device’s battery management system is made up of circuit boards.
The type of board and its complexity depend on the battery it supports.
How Does a Battery PCB Work?
There are two essential parts inside the PCB that is connected to the battery.
These are the PCB switch and the controller.
The controller keeps an eye on the voltage, current, and power levels.
When the controller issues the command, the switch toggles.
The battery management system of the device combines the actions of both.
The Battery Management System’s PCB keeps your batteries in good condition.
Applications of Battery PCBs
Devices used for a variety of applications include the Battery PCB inside the BMS for safety reasons (battery protection).
The Battery Management System cannot run without the Battery PCB.
These applications include:
- Cellphones, including smartphones and satellite phones
- PCs (laptops, desktops)
- Automotives – Battery-powered electric vehicles and ICE vehicle components
- Medical devices using batteries that are use for health monitoring (e.g. thermometers, blood pressure monitors)
- Medium-sized consumer electronics, such as kitchen/home appliances

As a special option, we can also create the layout in accordance with your specifications.
Battery PCB Fabrication
Not all devices have a PCB for battery safety. But every lithium-based battery-powered device must have a PCB, a Protection Circuit Module, or a BMS.
Although the terms BMS and Battery PCB are occasionally used interchangeably, they are not the same thing.
Remote controls and other 3v-7v devices are ones that exclusively use Battery Protection Circuit Boards.
A BMS will have integrated circuits if you have one (sometimes called ASIC).
Other parts include inductors, diodes, capacitors, and resistors.
In order to keep the battery safe and functioning properly, the Battery PCB will monitor voltage state by processing the data available. The types are as follows.
Depending on the battery it supports, we can categorize the types as follows:
- Battery Packs Made of LiCo (Lithium Cobalt Oxide)
- Battery Packs for LiMnNi and LiFePO4
- BMS for Li-Ion and LiFePO4
- PCBs for NiMH Battery Packs
Use this PCB to ensure that your battery device and power rechargeable solutions run smoothly.
