I have run 18 volt, 14 volt, and even nine volt battery tools for years on twelve volt car batteries. From TI's datasheet: https://www.sparkfun...ents/LM7805.pdf. Even though it is "an hour a day", it is still 10 starts per hour. If in fact this is a 12/24 volt 4spd or 5spd it will not make a difference. This digital transformation requires different processes and dedicated process support tooling. I know my supply is a lot higher for the motor to take but i want to try using it, At first i tried Directly hooking my motor to 24v power supply out of curiosity, the motor runs for 2seconds and the power shuts down and turns on … Thanks desertfox. I assume you do not have any definitive info from the manufacturer about higher voltage operation and acceptable quantity of starts/hour. A larger motor is not really an affordable alternative because the pump and motor are one assembly. When it's hot the voltage regulator may overheat. I was thinking a dual port charger using a pair of 4 or 5 AH 18V batteries should be capable of 5 or 6 amps at 12V which would run a mobile rig on low power TX for a good period of time I would think. Looking to replace it with 3 - 6 volt instead. i would still just wire the relay 12 volts. You might be able to power a 12V device with 18V, but not for as long. (or whatever in between). Once you've done this replacement, you'll need much larger power wires, assuming you want the same torque. The 18V to USB adapters that RIDGID and others have for sale got me thinking about a 18V to 12V down converter that could power some high amperage 12V DC equipment. The motor will take a higher voltage most of the time, but will heat up more and wear out much faster. "12 volt" batteries really run between 11.5 and 14 or so. Already a Member? 1. That's why hand controllers are designed with the regulators close to the LCDs. Try it and see if it works. Tell us about your project. DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging, Community Forum Software by IP.BoardLicensed to: Cloudy Nights, This is not recommended for shared computers, Help - In Need of Crash Course in Planetary Imaging, Quark Chromosphere and Orion 120ST... trying to make it work. The over-voltage will allow the motor to draw more current. Even little computerised things like microcontrollers (in small GOTO mounts) which might be regulating 12V down to 5V or so - the regulators may overheat leading to unreliable operation if left running for more than a few minutes. Already a member? Each of these regulators can deliver up to 1.5 A of output current. Thanks John, interesting site, handy to have around... Meade used to fuse the LX200 at 1 amp, then recommended 2. These applications include on-card regulation for elimination of noise and distribution problems associated with The fuse is rated at a set number of amps, that is far less than the wires can handle, and it blows before the wires do. If you were to run a 12v motor off a 24v battery the stall current could then be excessive if it weren’t limited by the controller. Use Upwork to chat or video call, share files, and track project milestones from your desktop or mobile. 1000lbs pushing capacity. I have had the starting battery run down after 3 or 4 trips to where it wouldn't start the motor. Re: Can you run a 24V motor on 12V battery? not very long by the sounds of it. Since 12V lead-acid batteries were originally designed for cars, there is a lot stuff that runs this way. The standard voltage regulator is the LM7805 that delivers 5vDC or ta a similar 3.3 volt regulator. I think Walterke has it right. 2. Also, running a battery hot will drastically reduce its lifespan, and running it really hot is very dangerous. If you connect a 12v device to an 18v power supply, you stand a good chance of letting the little bit of smoke escape. Probably depends on your operating conditions. This may be a bit of trial and error. An analogy: You can probably safely move 12 tons across a bridge rated for 10. I understand it would generate more heat. For astronomy equipment the only thing that would put a 12V battery in danger is a short circuit. This smoke is necessary for the functioning of the device. Maybe you could hook up a potentiometer to dial up the power as needed? I was thinking this could be good for someone with a 24V PV battery bank or perhaps a 12V when they have an additional 12V battery they could put in series to get 24V for operating these tools. You’ll need the hex wrench to connect the shaft in the center. Might reduce some of your problems. I've used a 9v drill with a 12v … Please let us know here why this post is inappropriate.
