1470-2068-5-ND 1 Output 15V 400mA 9V – 36V Input

This 3.7V Battery Charger TP4056 module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. In addition to safely charging a lithium battery, TP4056 BMS Board also provides the necessary protection required by lithium batteries. The TP4056 is suitable for USB power and adapter power supplies. Due to the internal PMOSFET architecture and anti-reverse charging path, no external isolation diodes are required. Specification of TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection BMS: Charge module: Linear charging. Current:1A adjustable. Charge precision:1.5%. Input voltage:4.5V-5.5V. Full charge voltage:4.2V ± 1% Led indicator: red is charging Green is fully charged. Input interface:micro USB/mini usb/type-c usb Work temperature:-10° to +85°. Inversed polarity: NO.

Quick specifications of the HW-632 (XH-M603) module (copied from the seller’s page) are: Input Voltage: DC 10V to 30V Display Precision: 0.1V Control Precision: 0.1V Voltage Tolerance: ±0.1V Output Type: Direct Output Battery Voltage: 12V to 24V Dimension(mm): 82 x 58 x 18 It accomplishes this with a small microcontroller, two voltage regulator chips, a bunch of discrete components, two microswitches, a PCB screw terminal block, an electromagnetic relay, one red LED and a 3-digit LED display. All in all, it looks like a compact module. Below you can see an annotated figure of the HW-632/XH-M603 module.
