Photo and product description

产品参数:
TP5000锂离子电池磷酸铁锂电池 1A电流 4.2/3.6V 功能：对锂电池及磷酸铁锂电池充电。充满自停。红绿双灯指示。尺寸：21.514.54.2mm 用法：TP4056 4057充电板用法相同。 1、锂电池只需接好5V电源，输出B+B-接好电池即可。充电中红灯亮，冲满自停，充电完毕绿灯亮。 2、用于磷酸铁锂电池3.6V，只需烙铁焊开两焊盘之间锡点即可。电源电池连接方法如上述不变。如需改回充4.2V锂电池，利用焊盘沾焊锡连回即可。

产品简介：

优点：开关降压模式，效率比线性充电电路高，发热也小很多。充电电流1A，在恒流全程充电保持1A。不需要额外散热，减小了发热对充电电流的影响。减小充电时间。可选普通锂离子锂聚合物电池或磷酸铁锂电池，仅需一个跳线即可更改设定。
参数：
输入：4.5-9V
输出电压：4.2V/3.6V 正负1% （电路板默认锂离子电池4.2V）
输出电流：默认1A
效率测试以后会详细描述，如果买家自己测试效率，不建议测试电池端电压，请注意跳过Rs采样0.1欧姆电阻测试，测试中输入电源接近电路板，减小连线长度都会对效率测试有影响，建议输入端增大电容测试。电压电流测试建议串有精度的电流表不建议直接读电源数显。电流的测试可以直接串联在电池正极，只需要确保电池低于3.9V使用大量程电流表测试即可。
