Charge Control Relay Module CD63L from ICStation.com 

XY-CD60 manual 1.Function: 1>.Module supports 2 working modes: Charging Control P-1 and Discharging Control P-2. 2>.Charging Control P-1: This mode is used for charging control to prevent overcharging.Display symbol IN indicates charging mode. 3>.Discharging Control P-2: This mode is used for battery discharge control to prevent battery over-discharge and delay battery life.Display symbol OUT indicates discharging mode. 4>.Battery voltage percentage: It is value get from battery voltage V, Lower Limit Voltage Value dn and Upper Limit Voltage Value UP. Calculation formula: V/(UP-dn). 5>.Automatic parameter check: Screen will display and flashing ERR if the Lower Limit Voltage Value dn is more than the Upper Limit Voltage Value UP. 2.Charging Control P-1 Mode: 1>.Input terminal connect DC 6V-60V charger which use for battery. 2>.Output terminal connect 1pcs DC 6V-60V battery. It will display 0.00V and nbE if the battery does not meet the requirements. 3>.Output turn ON and the input charger starts charging the battery if battery voltage is less than the Lower Limit Voltage Value dn. 4>.Output turn OFF and the input charger stops charging the battery if battery voltage is more than the Upper Limit Voltage Value UP. 5>.The symbol IN will flashing when charging. 6>.Support set parameters: 6.1>.Upper Limit Voltage Value UP: Maximum voltage of the battery. Stop charging the battery if it exceeds this value. It is also the overcharge protection voltage value. 6.2>.Lower Limit Voltage Value dn: Battery allowed minimum voltage. Start charging the battery when the battery voltage is lower than this value. 6.3>.Charging Time OP: 6.3.1>.Set battery charging time. 6.3.2>.Turn ON charging time control function when the OP parameter value is more then 00:00. Minimum set time value 1minute. 6.3.3>.Turn OFF OP control if set 00:00. 6.3.4>.Start the timer when turn on output to start charging. 6.3.5>.Module turn OFF output to complete a charging process when timing is completed. 6.3.6>.Module automatically turns OFF charging time control function if battery voltage is less than the Lower Limit Voltage Value dn and flashing H:ER that means the unreasonable time parameter setting. It means insufficient charging and needs to continue charging the battery. Press any key to stop flashing. 6.3.7>.Record and display charging time if disabled Charging Time OP when short press button SET. Clear time if at next charging or exit charging time display interface. 6.4>.Turn ON Delay Time dOP: Set the delay interval between the first and the second charging. The time range is 0~999second. 3.Discharging Control P-2 Mode: 1>.Input terminal connect 1pcs DC 6V-60V battery. 2>.Output terminal connect suitable load. Note the output voltage is same to battery. 3>.Output turn ON and the battery starts to discharging if battery voltage is more than the Upper Limit Voltage Value UP. 4>.Output turn OFF and the battery stops to discharging if battery voltage is less then the Lower Limit Voltage Value dn. 5>.The symbol OUT will flashing when discharging. 6>.Support set parameters: 6.1>.Upper Limit Voltage Value UP: Threshold value to allow battery discharge. 6.2>.Lower Limit Voltage Value dn: Battery allowed minimum voltage. Stop discharging when the battery voltage is lower than this value. It is also the over-discharge protection voltage value. 6.3>.Discharging Time OP: 6.3.1>.Set battery discharging time. 6.3.2>.Turn ON discharging time control function when the OP parameter value is more then 00:00. Minimum set time value 1minute. 6.3.3>.Turn OFF OP control if set 00:00. 6.3.4>.Start the timer when turn on output to start discharging. 6.3.5>.Module turn OFF output to complete a discharging process when timing is completed. 6.3.6>.Module automatically turns OFF discharging time control function if battery voltage is more than the Upper Limit Voltage Value UP and flashing H:ER that means the unreasonable time parameter setting. Press any key to stop flashing. 6.3.7>.Record and display discharging time if disabled Discharging Time OP when short press button SET. Clear time if at next discharging or exit discharging time display interface. 6.4>.Turn ON Delay Time dOP: Set the delay interval between the first and the second discharging. The time range is 0~999second. 6.5>.Discharge Turn ON Forced Start Time FOP: 6.5.1>.This function is used to prevent the device from starting instantly and reduce the battery voltage, so that it is lower than the Lower Limit Voltage Value dn and causing the module to automatically turn off the output and causing the battery can not discharge properly. 6.5.2>.The module will check the battery voltage again if enabled Discharge Turn ON Forced Start Time function. 4.Button Description: 1>.Long press means need keep press for more than 5second. 2>.UP button: 2.1>.Short press to switch display charging/discharging time and battery voltage percentage. 2.2>.Long press to switch work mode. IN is Charging mode and OUT is Discharging mode. 2.3>.Short/Long press to increase parameter value at parameter set mode. 3>.DOWN button: 3.1>.Short press to turn ON/OFF output. 3.2>.Long press to turn ON/OFF display status L-P (power saving mode): 3.2.1>.ON: Turn ON power saving mode. The display screen will turn OFF after 5~10minutes.Press any button to resume display. 3.2.2>.OFF: Turn OFF power saving mode. The display screen will keep ON all the time. 3.3>.Short/Long press to decrease parameter value at parameter set mode. 4>.SET button: 4.1>.Short press to automatically switch/query display parameters UP/dn/OP/DOP at charging mode and UP/dn/OP/DOP/FOP at discharging mode in normal display interface.

Cool unit. Can be used yo modify old school battery chargers(proper ones with transformer) and run them as automatic. May need separating the board and connecting voltage measurement directly from battery but does the job

Hours Expired Already 😂 Probably "health" as you suggested, that would be a handy feature for charging a known battery pack. An interesting device with many possibilities, thank you for sharing it with us. Regards, David

Very cool little circuit one can buy for less than $10!

I find that those relays may handle the rated current but they can't handle the initial spark and it eventually welds the contacts together.

That backlit LCD has become ubiquitous, I have seen it on so many relay modules, and in fact I have a thermostat relay with it.

Julian, did you notice that for down the 7-segment display shows an upside-down Up, ie, dn?

Julian I have the xy-l30a charge controller or upper voltage limit disconnect. 30a with a 6vdc to 60vdc range, even though the instructions say not to exceed 48vdc. With that in mind, I wonder if a small 100w 12vdc solar panel or even a larger residential 300w panel could be used by direct wire? This would be mppt in a way. The 300w panel outputs at max sunlight around 39vdc, well within max volts and current. What is your opinion? I would fuse this ofcourse.

Do you know module that will discharge to output when input x voltage reached? Like cap dump where cap go up to X(set to x volt) then it can discharge

I suspect it stands for “health” because the timer ran out before it reached the lower voltage limit. That flashing display is really quite annoying.

Is that m5433 regulator used to regulate voltage to the display circuitry?

Can you tell me how I can find one of those current limited power supply units?

HEA acronym means Happily Ever After. End of charging. Lol

Clear as mud.

everything is good, except the fact that any relay is very unreliable, contacts can weld together

High Elapsed Accumulation? 😄

Are there any with SSR relay.?

Hmm did you say we will have another video to watch 😞

NBE is No Battery Voltage where E represents Voltage. Although the website you linked says "No Battery Connected"

Happily Ever After?

nBE = No Battery Equipment

6 ads in 13 minutes. I stopped watching after that.

very good explain, now i need look for when solar feed battery that day time (LDR Light Dependent Resistor) switch on feed any on, till dark time switch off dont feed any, save battery for use other. hope you know what i mean.
