Battery saver

It protects my dewalt batteries from the death drain while in my daughters powerwheels.

Should have ordered something in AC and not DC

I have yet to test it. I thought I was ordering an AC to use on my train layout. I don't know if DC will work on the same since track voltage is AC.

Works for 2 18v ryobi in scooter

So they do work but just as other stated they don’t shut off once it cuts voltage so set the voltage cutoff above the minimum amount to prevent damage. Give yourself time to change battery and no box either. But junction boxes can be purchased cheap to contain it. Or pour silicone over the bottom to insulate. But I would go the junction box. I buy these for my audrino chips all the time. Just get proper dimensions and I dremal slots out for wires so device doesn’t have to be removed from box. Obviously this isn’t ideal if your looking for waterproof. But that can be purchased as well if moisture is a issue

No instructions, inacurate voltage measurement, stopped working after a few weeks

I have a 24v LiPO4 solar system to power security cameras and driveway gate. I installed two of these - one to remove power from non-critical devices when battery voltage was low, and a second to disconnect the battery to prevent damage if the battery voltage was really low.I measured the battery voltage with a multimeter - one board was out by 0.3v, and the other by 0.7v (with battery voltage ~26v). There is no calibration function on this board.There are no instructions included, but I figured out how to operate it by looking at similar devices.One of the two boards stopped working after a couple of weeks, the second board has been working for a couple of months.There are much better voltage comparators available on Amazon - don't waste money on this one.

Works great!

I've used a bunch of these in various projects . Re powering some older power tools, kids power wheels toys, a diy battery bank and so on. Works good for pretty much whatever you want to use a power tool battery on. Easy to set up and use.

So far so good

I bought this to protect my Milwaukee batteries in a power wheels swap. I have went through 4 charged batteries and the disconnect has worked perfectly (I wired mine with a relay). Watch a YouTube video for programming the voltage limits.

El circuito si desconecta pero no se restablece cuando el voltaje es mayor al ajustado

El ajuste del medidor de voltaje está con un error de 3 décimas
