One of the sellers on Amazon has an image of the board, showing that 6V to 60V can be applied to the input power for the board and the load. That the best lowest voltage info I can find so far.
@@Electronzap thanks again! I believe the 6-60V module is a different model. That module is more expensive and may be overkill for the project and does not fit my budget when buying in large qty.
I'm not a good person to ask, but NiCad batteries are meant to be totally discharged. It's generally recommended to use them until they are dead. I've never wired them up in series, I don't know how you would go about that. I know even less about using NiMH. All I know is to use a proper charger for both of types, as they are tougher to charge than lithium batteries.
i like your presentation very well done but i need some help. i bought one of these and it turns on at 14 and shuts off at 12, is there one (similar size hopefully) that will turn on at 12(or lower) but shuts of at 14. i am trying to get the alternator light in a 59 ford to work again. thanks for your help
I don't know that I came across a module like that. I spent all my time focused on keeping batteries from discharging too much. Instead of a low voltage cutoff you could try searching for a high/over voltage cutoff module. I never searched for one, but anything you can think of, is probably out there somewhere. Good luck!
Old comment so you probably aren't working on that alternator light any more but what you could do is run the output from the low voltage switch out to another relay that has both normally open and normally closed contacts to reverse the contact. That would accomplish what you are trying to do on your '59 Ford. I would power the voltage sensor off the ignition so it doesn't draw power when the car is sitting.
@@shanesdiy thank for the reply, as you mentioned i did connect a relay to the circuit that operates the original alternator light. now the light come on when voltage is below 12.4 and off when above 13. there are many blogs from old car enthusiast wanting to activate the original alternator light. in spending much time last year reading these i never found a solution so I just figured it out. also, its off when the ignition it off. mission accomplished.
@@Electronzap you should skim thru this video you might find it interesting. th-cam.com/video/QOSJ4Ktob68/w-d-xo.html This particular electronic instrument allows the rechargeable battery to drop low enough that the device won't even power on. 😅 (And yes I have one, looking to modify it one day with a mechanical power switch.)
@@steffinolte5355 If it is a lithium battery (li ion, or LiFePO4), then you probably want to cut it off when the cells drop to 3V. Less than 2.5V per cell might damage them. If you have 4 cells in series, then you would want to cut off at 12V. Li ion cells can usually be charged to 4.2V and LiFePO4 cells can usually be charged to 3.65V.
I installed the same module with my china inverter i set my cutoff voltage to 11.3v so on load usually voltage drops so this module turn off my inverter once the inverter is off again my voltage increases then again this module turn on my inverter and it is working like loop ,, Could you please help to sol my problem ?
Thr voltage drops more while a battery is providing power and rises again when you remove the load. So, I think you need to set the inverter to a low enough voltage that you don't want to go lower than, and remove the load before it drops that low. Low voltage cut off isn't intended to let you drain the battery to a certain level, it's intended for making sure the battery doesn't drop to a dangerous level.

Will the Relay draw more current from the battery to keep the load connected?
Will it be efficient to use a low voltage disconnect involving a Relay?
Hello, and thanks for the video.
does it memorize the set value when you disconnect it?
Or do you have to set it again next time?
I think this remembers it.
Sir what is the best cut off for 60V?
Thanks! What is the lowest cut-off voltage?

Thanks man! Great explanation
Glad to hear! Thanks for watching!
Does it still draw current to keep the display on? So if you have it hooked up between the battery and device, the battery would still die overtime?
Yeah, it draws power from the battery for the display. So, you'd need to disconnect it or recharge the batteries sooner for smaller capacities.
Great video. Keep it up!
Thank you very much!
Can this module be used for 4 or 5 (perhaps more) cell nihm or nicd batteries? If no out of box, could it be modified?

Look for over charge protection module

I have one of theses and the lowest cuttoff votage is 7 volts. I need 6 Volts. Any suggestirons?
Unfortunately I don't remember ever seeing any low voltage versions.
But what is need to cut off the circuit for low voltage instead I see overvoltage protection more or less everywhere 🤔🤔
Rechargeable batteries are typically damaged when voltage gets too low. It's even worse to over charge them.
@@Electronzap ...my god.. thanks 😄...it increased my knowledge

@@Electronzap How low can I set one of these when using a Lithium battery? (Because they don't get damaged at low voltage)

I was just about to ask stackexchange for exactly this and decided to try TH-cam first. Thanks for the video
can u tell me max current for this modul?
It's got a 20A relay. So hopefully that much. Seller I got it from writes that the circuit breaker trips at 20A.
Nice
Thanks!
