1S 3.7V 12A 18650 Lithium Battery Protection Board

Overview:

The 1S 3.7V 12A 18650 Lithium Battery Protection Board can be used to protect a battery from overcharging, discharging, short circuit and overcurrent. This protection board is specifically designed to enhance battery performance and longevity, offering a range of features that make it a reliable choice for various applications.

Features:

• Without Balance: Designed without a balance feature for uncomplicated setup and ease of use.
• Without Balance/Signal Cables: Streamlined design without the need for balance or signal cables.
• Without Temperature Switch: Simplified configuration without temperature switch for straightforward implementation.
• The BMS Charge and Discharge Port is the Same: The charge and discharge ports are integrated for seamless convenience.
• Detection Circuit: Features detection circuits for over-discharge, over-current, and load short circuit protection.

Specification:

• Overcharge Voltage: 4.25V ± 0.05V
• Over-voltage Range: 2.4V ± 0.05V
• Charge Voltage: 4.2V
• Max Continuous Charging/Discharge Current: 12A
• Max Discharging Current: 17A
• Size: 40 x 12 x 3.5 mm (L x W X H )
• Weight: 19g

Instructions:

• B + : Connect to the positive battery terminal
• B-: Connected to the negative battery terminal
• P + : For the battery pack output - input positive
• P- : For the battery pack output - input negative

Note:

• Difference Between Split Port And The Same Port: Split port separates positive and negative poles; same port maintains equal charging and discharging currents.
• Enhanced Version And Balanced Version: Balanced version discharges high voltage cells, ensuring consistent voltage and improved battery performance.
• Battery Matching: Batteries must be properly matched in terms of voltage, internal resistance, and capacity for optimal performance.
• Parallel Connection: Connect batteries in parallel before series connection to avoid damaging the protection circuit.
• Battery Model: Choose the correct protective plate based on whether the battery is Li-ion or LiFePO4.
• Ensure input/output voltage and load current adhere to specified conditions to prevent excessive power consumption.
• Avoid prolonged operation of load current between upper limit continuous working current and overcurrent protection current.
• If battery cannot discharge after connection, connect a charger to restore normal operation.
• Refrain from touching the board during operation to avoid electrostatic damage to the protection board.

Package includes:

• 1 x 1S 3.7V 12A 18650 Lithium Battery Protection Board
