This video only demo how to set Battery Charging Controller. Diagram of wire, please read the manual.
XH-M601 or QW-024 Battery charging control board. Not easy to setup
Dont buy this board, not easy to setting for lithium 12.6 V DC.
Relay 12V, may be can work with 9 V DC
Below 7-8V/DC, may be not (our test)
Different XH-M601 and QW 024
Both of them, very precision compare XH M604
Small power consumption during standby.
XH-M601 only normal open relay or switch on and off, suitable for battery charging controller
QW 024 have normal open and normal close relay with 3 pin relay. Can switching battery power after charger, and move to load grid, and cut off the power battery again during charging the battery
In this video
00:00 XH-M601 or QW-024 battery charging voltage limiter board
00:09 3 component for test and learn : Multimeter or Volt meter, and Voltage adjustable
00:36 Board Function
01:00 How to setting XH-M601 or QW-024
Turn clockwise all trimpod until hear click
01:17 Set lower voltage First
01:31 Turn counter-clockwise
Turn side by side, turn full 2 times. But turnslowly, specially trimpot lower voltage controll
And until LED or Relay goes up, stop turn
That point, low voltage limiter. Relay start running connect adapter charger to battery. For get high voltage the battery during charging, or setup up voltase for relay off.
03:00 Set upper voltage
02:59 Turn second trimpot / PR2
Setting Upper voltage = setting relay off or stop charging
Turn clockwise, slowly, until LED Off / relay Off
03:28 Test 12V
04:27 Test 9V
04:44 Test 7V
With 7V, may be relay can't work, because power very low.
But system board still working.
04:58 Test with battery 12v
This tutorial only example.
Trimpot RP1 or RP2 potensio can adjust after installation.
Setting XH-M601 or QW-024
Actually not easy like manual
1.RP1:adjust storage battery start charging voltage (low voltage setting:clockwise becomes higher,counter-clockwise becomes lower)
2.RP2:adjust storage battery disconnect charging voltage (low voltage setting:clockwise becomes higher,counter-clockwise becomes lower)
This video explains how to set the XM-601 or the QW 024 model
We are looking for the easiest way to make settings
Minimum voltage, and maximum voltage
Why XH-M601 or QW 024 better compare XM big board or HW-632
Without display, small component, in idle condition
XM-M601 or QW 024 only 0.3mAh internal power consumption
Compare
HW-632 about 50mAh internal power consumption, specially LED Display need a small power active.
BEWARE, chip 555 timer going hot, if wrong wiring
This video only demo how to set Upper and Lower voltage
The DC line must be separated from the relay
