5pcs 5V 1A 18650 Lithium Battery Charger Board Power Bank: Perfect for Portable Charging Solutions

The 5pcs BMS 5V 1A 18650 Lithium Battery Charger Board DIY kit is a high-quality, 100% brand new product designed for power bank applications. This mini/micro USB power charging protection board is a convenient and versatile solution for portable charging needs.

The charge module used in the product is a linear charger with a current of 1A that is adjustable to your needs. The charging precision is 1.5%, ensuring that your battery is charged accurately and efficiently. The input voltage range for the charger is 4.5V-5.5V, and the full charge voltage is 4.2V ± 1%.

The LED indicator on the board is red when charging and green when fully charged, making it easy to see the charging status at a glance. The input interface on the board is compatible with micro USB, mini USB, and type-C USB, making it a universal solution for charging. The board is also built to work in a temperature range of -10° to +85°.

The battery protection features on the board are designed to keep your battery safe from overcharge and discharge. The overcharge protection voltage is set at 4.28 V, and the overcharge lifting voltage is 4.00 V. The discharge protection voltage is set at 3.0 V, and the discharge termination voltage is 3.2 V. The board also has a battery over-current protection of 3A.

It is important to note that the ampere meter can only be connected to the 5V input end of the module. Also, it is recommended that the charging current should be 37% of the battery capacity. For example, if you are charging a 1000mAh battery, a current of 400mA is enough. The connection wire should not be too thick and the connect point should be good. If the input voltage is too high (such as 5.2V), the current will be less than 1000mA, which is a normal protection function to avoid burn damage to the chip. Reverse polarity is not allowed on the board.

In conclusion, the 5pcs BMS 5V 1A 18650 Lithium Battery Charger Board DIY kit is a great solution for portable charging needs. With its adjustable current, universal input compatibility, and safety protection features, you can trust this board to safely and efficiently charge your batteries. The package includes 5 pieces of Lithium Battery Chargers.
