Here's a link to a good SOURCE: s.click.aliexpr...
This little charge controller allows you to control the charge state of your batteries. Great for solar or lithIum batteries.
There is a relay which starts and stops the charging through a relay. The controller lets select these both limiits. Charging current limit need to be taken care y the source. Solar charging might the best application for this board.
Good clear instructions 👍
The low voltage setting is the voltage it starts charging. the high one is when it stops charging. That is all it does. Added a watt meter for fun and an undervolt protector to cut of the load when getting below 10.6 but those 3 items ( XH-M603, watt meter and undervolt) draw too much from my 6 (very bad 800 mah) 18650's in 3s2p to make it though the night with out any load!
hi can you explain how to make it activate to 12.8 and cut it if it goes down of 13v?
we have bought for a machine that is connected to a vehicle.
thanks and regards.
The relay on this board is a 12V relay. However, this board is presented as operating between 12V and 24V.
Does it work by connecting a 24V battery and obviously with a 24V charger?
wow!!! thank you for your explaination
Thank you this is amazing!
Hello, thanks for the video. I have a 5w 12v max 21v solar panel to trickle may car battery. I am using a xhm601. Would you know where does the positive and negative connect in k0 and k1 port from the solar panel? Also, i want to keep the max voltage to 14.3v and min at 0 so that it keeps the trickle charge always on, is that possible?
Hi Friend, I am trickle charging my car battery through Dewalt 20V using LM2596 and it's working really good and have been using it for about an year from now. Now my question is I want to protect my Dewalt Battery from going too low on Voltage and I tried using XH-M609 and LM2596 together but it didn't work. Now what do you suggest me to buy which might help. I appreciate any help please.
I am assuming the circuit can function even when the battery voltage is very low by boosting the batter voltage to what ever the circuit needs to function. and it only opens and closes the relay as needed to charge the battery. Any idea what the maximum charge current this can handle? I also assume it is going to be limited by the size of the traces on the board?
Sorry about my english I from Argentina, I have a problem and I can`t solve this at the moment. My battery is 1.2 amp and this module discharges it quicly because the unit is taking 70mA. How I can solve this? Thanks.
Max charging current of this module?
yes i wonder that too. does it limit the current some how or wil stuff explode when my panels deliver 6125 watts? they are old panela. they do just 6 watts together on cloudy days. but in direct son on a good day they can still get to 125 watts.
Dear Hans max charging current of this module is 20A.
tried to work with this hw632, but when battery reached Low voltage level, relais cones on for a split second, goes OFF again, and ON for another split second, so on and so on... there is no charging at all, maybe the unit has a problem?
What if your solar panels have solar charge controllers on them and the solar generator has a solar charge controller on it would that be a bad thing? Is it better if the solar panel have a charge controller on itself then feed a regular charge controller. Or once the solar panel sends voltage from the panel controller it can go directly to battery without any worries?
Can this module take input of 20V from laptop charger and charge a Lead Acid 12v battery without any problem? I am worried because the laptop charger output 20v but battery is a 12v battery. Start charge volt i am setting in the module is 11.5 and cutoff voltage i set is 14V.
it's possibile recharge a 7.5 v battery from a 12v solar panel with this board?
Hi. Can i set the connect value to 13.4v and set the disconnect value to 13.7v?
I was hoping to use one of these to charge the vehicle battery via solar, so the on voltage needs to be higher than the off voltage so it disconnects when the panels voltage falls.. it may not reach the higher 'off' threshold hence latch on indefinately... anyone know if the on/off can be inverted?
Mine worked for about one day
can you help me sir to explain what is 601,602 and 603 in my solar charger controller.
Hi sorry I'm using water wheel as generator. My issue is that I want to control the water using an electric valve. So when my battery reach the low voltage, the controller will open the water valve and the water will make the wheel charging my battery.. Does this type of controller already exist?
When I connect to battery still the lights do not come on ?
Sounds to me like you have a faulty unit or a completely dead battery.
Does it work with 18650 batteries or lead acid batteries or both?
This is similliar like step up and step down DC-DC bro?
How can I control for 24 volt
Will it stop when the battery volt will go under minimum set voltage
Подскажите реле отключения нагрузки при заряде? Нужно доработать эту плату!
if you have cells in series how do you stop one pack charging faster as is known to happen? how will you balance the charge
Project 806 Camper I find that you only need to balance charge after about 20 cycles. My new 18650 box allows me to balance charge in the side of each box so I do a balance every 20 cycles. You can also easily remove the batteries if you find one that's faulty so it makes life easier. You can see the box on my video I did after this one.
I always charge at 4.2v and that never happens for me. My packs are made in parallel only and I boost them to 12v. I prefer that.
Why can't connect first solar wire?
Tried to set no lights when I fix to battery no lights ?
I noticed the voltage shown on the LCD is different from that on my multimeter. Any idea whether there is a way to calibrate this?
Interesting. I haven't found that with mine but I will check a few more units as you have mentioned this. You could use a buck or boost converter between it and the batteries just to be sure. But for me less is more. I will check though.
OpenSourceLiving I think I found the mistake I made. I failed to unplug the battery from the solar panel when I told the measurement.
HOW TO CONTROL BATTERY CHARGER SO THAT THEY NOT OVERCHARGING 80% AND NOT OVERDISCHARGE 20%
Will it safe the set voltage (is there a memory function), if its disconnected from any power source?
It seems to save the last set voltage so yes.
@@SocialHigh thank you very much :)
Can this be used to charge 100 amp battery?
Well it works pretty well on a 200 amp battery.
Could I have a diagram drawing
If the battery is low will it still show lights
Not if the battery is dead.
I dont think this charger does CC CV charger for a proper charging of the 18650's?
Not sure why it wouldn't. It's working for me :)
This relay stops charge when set voltage is reached. It does not continue to charge until amps die down and charge is complete. This is far from a charger but for the price, what do you expect.
@@andrewyanke1787 for continuous tickle charging type use , one can select 12.8v and 13v as both limits.
I don't understand what this thing is doing. Unlike most charge controllers I've seen, there is no load connection on it, so it won't cut off the draw on the battery when the batteries get dangerously low. Is the idea that it will start charging when the battery voltage drops to the low threshold, shut off when the batteries are charged, and do nothing when the batteries are draining until it gets to the low point? A real solar charge controller would charge whenever the batteries are below the high point, and shut off the load when the batteries get to the low point. So I guess you're going to use it as a charger, and not a charge controller, although I don't really get the point of the start voltage. I think you'll want it to charge even if your batteries are above the start voltage. But maybe I don't understand how it works or what you are planning to do with it.
If you put an 18v charger on the input, does it buck it down to the high voltage and leave it there until the batteries reach that state of charge, and then cut off?
It will buck the voltage from 10v to 30v and acts like a regular charge controller. I use it between a regular charge controller and my batteries to buck from 13v to 12v max.
It is common with Li chemistries to let them cycle a bit and not stay topped off. They dislike being fully charged.
@@SocialHigh so it is a buck converter internally for bringing down supply voltages?
Very good video sir thanks for showing, now i will try set mine up-- 10/10
can the display be turn off/on ?
No. It's on when the battery is connected.
it'd be nice tho. do you know what the top 4 pin holes are for? usb serial i hope...
batteries need current and how much current goes into them. This I would stay away
2 saattir konuşuyor sun kaç volt ile çalışıyor göstersen ya arkadaş
Dangerous! Always use a balance charger with lithium cells in series.
I have 2 deep cycle gel battery is it avaible ?
If you mean can yyou connect 2 deep cycle gel batteries. Yes. It works on any size and type of battery.
lipo battery 11.1v 6000mah?
Yes as it can be set to 11.1v max charge

Looks like a garbage piece that works backwards. This device will not provide power unless it sees proper voltage from the item your're looking to charge , awful design stay away. It's like having a battery charger that only works charging batteries that still have amble voltage...well then worth less as will not produce or provide power if you have a dead or almost dead battery. Hell....it won't even turn on even given 12volts from the supply side, only turns on if sees amble power from the source it's looking to charge.
He forgot to tell that this is is not for dead batteries seating dead in junk yards.. But all devices can not be for junkyard savvy applications.
My comment has to do with the fact it only has very limited usage parameters. The unit does not turn on or even work by giving it 12volt power, it only turns on by the power it gets from the battery it's looking to charge....pretty stupid...as if battery is low it won't even charge or even turn on. It should act like a trickle charger, or battery charger while remaining a battery tender. A $10 battery tender from Walmart is more practical (over all) as charges the battery, maintains the battery, and turns off on it's own once seeing proper voltage.
the item is a charge controller / NOT a battery charger
