Using batteries as DC power supply
How can I supply 5v voltage to circuit in a portable way?
First, if it''s really that important that this device be small and the batteries minimal, design it for 2.5-3.3 V power. Then you can use a coin cell directly. You will also find that most parts that run from this power voltage will draw less power than when running from 5 V. Second, you can convert between voltages with a switching power supply.
How to Power Your Guitar Pedals: Batteries, Supplies, FAQ
If you have a guitar pedal with 9V written on it, make sure you use a 9V power supply or battery. Keep in mind that while most guitar pedals use 9V, there are pedals out there that require a higher voltage. If you have a pedal that requires 12V, 18V, or even 24V, make sure the power supply you use matches that voltage.

Re: Using a 16VDC power supply with a PWM charge controller I have also been looking into using a power supply as a battery charger (in my case, for an odd size voltage). The most economical solution I have come up with is the EX line from Volteq/Mastech. This one looks like a good match for you.
Substation DC Auxiliary Supply – Battery And Charger Applications
Some systems at the substation may require lower voltages as their auxiliary supply source. A typical example of these systems would be the optical telecommunication devices or the power line carrier (PLC) equipment, which normally requires 48 V.If the power consumption of these devices is low enough, their supply can …
Charge car battery with lab bench power supply
Everything is great until you turn the power supply off with the battery attached... and the supply decides to self-destruct. Some lab power supplies - even a few made by respected brands - are infamous for being absolutely intolerant to back-feeding from low impedance sources such as lead-acid batteries.
Can You Use Battery Charger as Power Supply?
A computer power supply, for example, usually supplies DC voltage in the range of 12V to 24V, while most rechargeable battery chargers provide DC current within 13.0 V to 15.0 V (some can go as high as 19.0VDC).
How to Recharge Batteries with a DC Power Supply
You can easily recharge batteries if you have a DC power supply. All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric …
Can You Use a Switching Power Supply to Charge a …
First, you need to determine the voltage of your power supply. The voltage of your power supply must be greater than the voltage of the battery you''re trying to charge. For example, if you''re trying to charge a 12 volt battery, …
Powering ESP32 Projects with Batteries: A Detailed Guide
Li-ion 18650 cells provide 3.7V nominal voltage and capacities from 1,000 to over 3,000 mAh. Their larger size accommodates high capacity for long runtime. Requires protection circuit. LiPo packs output about 3.7V per cell (adjustable via cell configurations), with capacities ranging from under 100 mAh to over 5,000 mAh. Lightweight form factor great …
Easy Battery Hack Using a DC Power Supply
Batteries are direct current ''DC'' and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC power. They use a AC to DC power supply to allow us to charge the device by plugging it into the wall.
Using a dc power supply instead of batteries
I have a device which takes 4xD batteries which I would like to instead hook up to a spare wall charger. I have looked at the voltage of the batteries and it seems most batteries are 1.5V. My device has 4 of them (seemingly in series - but with 2 down one side and 2 down the next. Ie: simulate this circuit – Schematic created using CircuitLab
BU-405: Charging with a Power Supply
Put 30V DC or even more from your DC power supply onto the battery; current of the supply should be limited or you will damage the supply. First set the power supply, then connect it for a few seconds to the battery. Repeat that a few times. Then go back to step 1: 15V, limited to 1 amp. Once current is above a few 100 mA, lower your voltage to ...
Direct Current (DC): Definition, Symbol, and Examples
The battery supplies DC to start the engine and operate various components like lights, dashboard instruments, and audio systems. ... This DC power can be used to charge batteries or use inverters to convert DC into AC for home or commercial use. Electric Vehicles: Electric cars and bikes make extensive use of DC electricity. The …
Using deep cycle marine batteries as backup power supply
I took an old Watch Dog Sump Monitor and modified it to run 12 Volt water pumps, during a power failure. I had some used deep cycle batteries lined up, from someone that changes them out on their yacht every year.
What are the ways to make a dual power supply from a single …
For a quick and simple dual power supply, use two resistors in series connected in parallel with two capacitors. Connect the two ends to the battery or power source and BAM! You have a dual power supply. Typical values for bipolar converters like this are 100k-1M for the resistors and 47uf to 4700uf depending on the current draw of …
