Balanced 3S 60A PCB Protection Board for Lithium Battery
This protection board is designed for lithium batteries in a 3S configuration (three cells in series), with a maximum continuous discharge current of 60A and a balanced charging function. It is an ideal solution for protecting and optimising the performance of 18650, 26650 and lithium polymer batteries.
Main features:
- Nominal voltage: 3.7V per cell, with full voltage of 4.2V.
- Charging voltage: between 12.6V and 13.6V for the three cells in series.
- Maximum continuous discharge current: 60A (recommended to reduce if cooling is insufficient).
- Maximum continuous charging current: 15A.
- Material: high-quality PCB, green colour.
- Dimensions: 41 x 62 x 3.4 mm.
- Balanced function: keeps the charge balanced between the cells to extend battery life.
Typical applications:
- Ideal for electric drills with starting current below 120A and power under 260W.
- Use in standard rechargeable 18650, 26650 and lithium polymer batteries.
- Protection against overcharge, over-discharge and short circuits in 3S battery systems.
Additional technical specifications:
- Requires batteries with discharge power of 15C-20C (three batteries) or 10C-15C (six batteries) for successful starting.
- The wiring map must be followed: 0V, 4.2V, 8.4V, 12.6V, 16.8V to avoid damage.
- It is recommended to connect a non-polar capacitor (10uF-100uF, >25V) between the positive and negative terminals of the motor to avoid reverse spikes.
- For batteries in series, make sure each group has the same voltage before using them together.
Package contents:
- 1 x Balanced 3S 60A PCB Protection Board for Lithium Battery.
This board is an essential component for anyone looking to protect their lithium batteries and improve their performance and safety in electronic applications and power tools.

Customer Questions & Answers
What are the exact dimensions, weight and contents included in the box for this product?
The board measures 41 mm x 62 mm x 3.4 mm, is made from green PCB material and one unit is supplied per box. The typical weight of a PCB of these dimensions is under 25 g, although this may vary slightly depending on the manufacturer.
What is the maximum current and recommended operating temperature range to avoid damage?
The board allows a maximum continuous discharge current of 60 A and a maximum continuous charge current of 15 A. In environments with insufficient cooling, it is recommended not to exceed these values. The typical operating range for PCB boards is 0 °C to 60 °C; operating outside this range may reduce protection performance.
What precautions or common issues should be considered for safe installation, and which standards does this product comply with?
It is crucial to follow the wiring diagram and avoid intentional short circuits. When connecting the motor, it is recommended to add a non-polar capacitor (≥25 V, 10-100 μF) between the terminals to filter reverse spikes. Although it performs the typical functions of lithium pack protection, specific compliance with international standards (such as IEC 62133) is not stated, so additional requirements should be checked for critical industrial applications.
What type of batteries is this protection board compatible with?
It is compatible with 3S lithium batteries, including 18650, 26650 and lithium polymer batteries.
What is the maximum discharge current this board can handle?
The board supports a maximum continuous discharge current of 60A, with a recommendation to reduce it if cooling is insufficient.
What does the balanced version of this board do?
The balanced function keeps the charge balanced between the cells to prevent overcharging and extend battery life.
Can I use this board for electric drills?
Yes, it is suitable for electric drills with starting current below 120A and power under 260W.
What should I keep in mind when connecting batteries in series with this board?
You must make sure the voltage of each battery group is the same and avoid short circuits by following the wiring map provided.
