Lithium-ion battery protection and charging module 3S 10A 18650

The OKY3602 is a Lithium-ion battery protection and charging module designed for 3 series (3S) connected 18650 lithium-ion battery cells. Commonly referred to as a Battery Management System (BMS), it provides essential protection features to ensure the safety and longevity of your battery pack.

Key Features - Overcharge Protection: Prevents damage to the batteries from being charged beyond their maximum voltage.

- Over-discharge Protection: Prevents the batteries from being discharged below their minimum voltage, which can cause irreversible damage.

- Overcurrent Protection: Limits the current drawn from the batteries to prevent overheating and damage.

- Short Circuit Protection: Immediately cuts off the current flow in the event of a short circuit, preventing fire or explosion.

- Automatic Recovery: Automatically cancels protection after protection conditions restore.

- Balanced Charging: Ensures that all cells in the battery pack are charged equally, maximizing the pack's capacity and lifespan.

Ideal Applications and Benefits - DIY Power Banks: Perfect for creating custom power banks with enhanced safety features.

- Portable Solar Chargers: Protects batteries in solar-powered charging systems, ensuring reliable performance.

- Electric Bicycles and Scooters: Ensures safe and reliable battery operation in e-bikes and e-scooters.

- Uninterruptible Power Supplies (UPS): Provides a safe and reliable power backup solution.

- Custom Lithium-ion Battery Packs: Suitable for various applications requiring protected lithium-ion battery packs.

- Massager rechargeable battery

- LED ready light power supply

- 12 V electronic products

- Solar street lamp battery

- Power backup monitor

Important Usage Information This module is designed for ease of use and compatibility with a variety of 12V lithium batteries. For optimal performance, please consider the following:

- When assembling a battery pack, ensure all batteries have the same voltage level before connecting to the BMS. If voltages differ, cycle each battery (charge/discharge) to equalize them.

- The module is based on the chip (controller) S-8254A, and performs the function of protecting the charge-discharge LI-ION elements of type 18650.

- Strictly follow the drawing wiring 0 V (B), 3.7 V (B1), 7.4 V (B2), 11.1 V (B +), and avoid intentional short circuits!

- Once you have charged the first line, it will have output.

- When using the battery in series 3, please ensure that the voltage of each battery is the same. If not the same, please fully charge each set of batteries before use. When the discharge is tested, the battery in which the voltage drop is the fastest indicates a difference between that battery and the others.

Important Safety Information Warning: The protection board is not suitable for lithium iron phosphate batteries, lamp hernia, hand drill battery, electric battery fish, electric bicycle battery, car battery for children, 775 (4A) motor, or 1 W fish eye LED light. Please ensure compatibility before purchase!
