What are the wiring methods for 18650 battery 3.7v 2200mah protection boards? What is its function?

　　Introduction to the wiring circuit and method of 18650 battery 3.7v 2200mah protection board. As a safety protection device for lithium batteries, the protective board must not only work reliably within the normal operating current range of the equipment, but also act quickly when the battery is accidentally short-circuited or overcurrent to protect the battery core. Introduction to the wiring circuit and method of 18650 battery 3.7v 2200mah protection board. As a safety protection device for lithium batteries, the protective board must not only work reliably within the normal operating current range of the equipment, but also act quickly when the battery is accidentally short-circuited or overcurrent to protect the battery core. The principle of 18650 battery 3.7v 2200mah protection board is very simple, and it is also simple to make. The requirements for customers must be very clear, down to the component model, process requirements, voltage requirements, current requirements, output port connection, charging, etc.

　　18650 battery 3.7v 2200mah protection board wiring circuit and method

　　The wiring methods of each 18650 battery 3.7v 2200mah protection board are different depending on the number of series, and the wiring methods of the same port and separate ports are also different. If you want to be precise about each product, please check the protection board details page, but the overall wiring remains unchanged. Due to the active nature of lithium batteries, a protective board must be installed when using lithium batteries to prevent overcharge, discharge and overcurrent of the 18650 battery 3.7v 2200mah. Let me introduce how to wire the 18650 battery 3.7v 2200mah protection board.

　　The 18650 battery 3.7v 2200mah protection board is to protect the charge and discharge of the series-connected 18650 battery 3.7v 2200mah pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (usually 20mV), achieving even charging of each individual cell in the battery pack. Effectively improves the charging effect in series charging mode; simultaneously detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single cell in the battery pack to protect and extend the service life of the battery; undervoltage protection ensures that each When a single battery is being discharged, avoid damage to the battery due to over-discharge.

　　Lithium-ion batteries are both batteries + protection boards. The 3 wires will only appear on the protection board, and the battery will always only have 2 wires. There are two types of lithium-ion batteries. Obviously the 3.7V one is non-aluminum iron phosphate and can be replaced directly.

　　How to connect the 36V 18650 battery 3.7v 2200mah protection board?

　　1. First connect 12 lithium batteries in series. If there are 24 sections, they can be connected in parallel first and then in series!

　　2. Connect the negative terminal of the battery pack according to B. B1_B2_B3,,,,B10_B1l_B2 in sequence

　　3. Same interface: the positive electrode of the 18650 battery 3.7v 2200mah pack is: the positive electrode for charging and discharging. C: Can be used as the negative electrode for charging and discharging.

　　4. Branch interface: The positive electrode of the 18650 battery 3.7v 2200mah pack is the positive electrode for charging and discharging. C: Can be used as the negative electrode for charging. D: It can only be used as the negative electrode of discharge.

　　The role of 18650 battery 3.7v 2200mah protection board

　　1. Overcharge protection to prevent damage to the 18650 battery 3.7v 2200mah pack caused by overcharging.

　　2. Over-discharge protection to prevent over-discharge from causing the battery life to decline.

　　3. Overcurrent and short circuit protection make lithium batteries safer and more reliable during use.

　　4. Small size, suitable for a variety of 18650 battery 3.7v 2200mah packs.
