Maxmoral 2pcs TP4056 Lipo Battery Charging Board Micro USB Port Lithium Battery Charger Module 1A

#ad
Maxmoral #ad - The input reverse connection has no effect on the chip, but the output battery end reverse connection will burn the chip. The charging connection wire should not be too thin or too long, which has high resistance, and lead to the battery voltage is step-down. For example, the charging current of a 1000mAH battery is 400, that is enough.

Specification: product name: lipo battery charging Board Input Interface: Micro USB Charging Mode: Linear Charging Current: 1A Adjustable Charging Precision: 1. 5% input Voltage: 4. 5v-5. 5v full charge Voltage: 4. 2v charing indicator: red-charging, green-Full Charge Working Temperature: -10 to +85 Degree Celsius Weight: 2.

Maxmoral 2pcs TP4056 Lipo Battery Charging Board Micro USB Port Lithium Battery Charger Module 1A #ad - 3g size: 25x19x6mm attention: -the ammeter for current testing can only be connected in series to the 5V input of the charging board. After all, charging current is high. Too much charging current, fast charging speed but poor effect, the battery will be step-down. The best charging current is 037c of the battery capacity, which is 0

37 times of the capacity. High voltage will lead to the chip heating and reducing the charging current automatically to avoid damaging.
