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.
