Module parameters

Module Properties: switching battery charger module

Input voltage :4.7-24V (when the input voltage exceeds 12V, output current of 2A, when requested to enhance heat dissipation, suggested the use of our products with a metal case)

Charge voltage: 4.2V

Charge voltage accuracy: ± 1%

Suitable for battery: 3.6V 3.7V lithium battery 500mAh ~ 15000mAh

Charging current: 0.5A, 1A, 1.5A, 2A, 2.5,3 A optional (can be up to 3A) (charging current greater than 2A, only the input voltage 5V, suggested the use of our metal products.) Default shipping is charge current 2A.

Charge-Current Accuracy: ± 5%

Charge indication: Blue LED charging light, blue LED off the battery is full (recommended blue LED into a micro-light to continue charging for an hour, which would allow a more full battery charge)

          LED to do with housing need to take instructions



Battery anti-reflux: the default is no such function, if necessary, in the series with a diode input power can be positive (eg SK34, SK54, SS34), etc.

Efficiency: Up to 90% (5V Input) 12V input efficiency is about 85% 24V input efficiency is about 80%


Switching frequency: 500kHZ

Input under-voltage protection: 4.2V (TYP)

Battery intrusion current: 10uA (without battery polarity protection)

Operating Temperature: Industrial (-40 *C to +85 *C) (metal) (ambient temperature exceeds 50 degrees Qingjiang the amount of use)

Full load temperature rise: 30 *C
Reverse battery protection: No

Input Reverse Polarity Protection: No, if you need to reverse protection, reverse polarity protection with our board, or series diode at the input (such as SK34, SK54, SS34), and so on.


Connection: Welding, DIP-24 standard package can be soldered directly on the PCB (the need to install pin when the shopkeeper asked to buy)

Input: IN + input is level, IN-type negative
Output: BAT + battery is level, OUT-battery anode

Timing: first connect the battery, and input power can be loaded with automatic reset function 4.05V
