Powering 12V LED strip lights with a 12V deep cycle battery

electronics.stackexchange.com › questions › 186657 › powering-12v-led-strip-lights-with-a-12v-deep-cycle-battery

Can you reconnect strips in series 12+12=24V, then you can use boost dc-dc converter from your battery around 12V to stable 24V?
This arrangement will give you stable light that is not dimming during battery discharge. That's what I did with my emergency light - there is 6 strips with 3 LED each. I connected three of them in parallel (12V), connected other three in parallel(12V), and connected those 2 pairs in series which gives 24V. Then I bought this boost converter (about 3 USD) and it still works perfectly.

Answering your question: you can't use a 12v battery to power a 12v led strip directly. a fully charged lead acid will have 13.8v which will burn out your led strip if you are doing so. You don't need a current limited device. What you need is a voltage regulator. You need exactly 12v to run your led strip. I will suggest a buck dc-dc converter. you can buy one in ebay for $3; cheapest way to go is to use 3 diodes. 0.6x0.6x0.6=1.8. it will drop your 13.8v battery to 12. making it more safe to run your led strip, but the problem is when the battery voltage drops, so as your led brightness, and another problem for simple diodes is energy efficiency; 3 diodes will produce many heat and waste your battery life.

r/led on Reddit: Would this simple setup work to power 12v LED's for a light box off a battery?

April 12, 2023 -

I'm looking to backlight a light box that will hang on a wall. Will be using some 12v LED strip lights. I'd like to run this off a rechargeable battery so it can hang without cables and/or a location without an outlet nearby. I'm not looking for hours and hours off battery life but a solid hour wouldn't hurt. This is just a personal project, it probably wouldn't see much regular use. So moving the box or occasionally running a cable to recharge doesn't bother me.

Would/could this be as simple as using something like this?

https://www.amazon.com/6800mAh-Rechargeable-Protable-Lithium-DC12680/dp/B074TC4XW4/ref=sr_1_9?keywords=12v+battery+pack+for+led+lights&qid=1684775364&sr=8-9.

If the barrel plugs happen to match up to a set of lights/controller I already have, cool. If not I have enough experience soldering to rig something up. Ideally I'll set it up using a wireless controller/remote that is common with LED strip lights. I've messed around with stuff like this before but it's always been wired directly.

If the battery makes this more complicated than I'm expecting, just let me know. Any simple (or complicated) advice would be appreciated.

you can use a tool similar to this to get a good idea / approximation of 'runtime'. https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-battery-life edit: forgot to mention. if you have a way to power them now and a meter handy, use that to determine how much power it's using, then use that as the second value in the calculator. the battery you linked looks like it's 6800mAh. also, here's another quick calculator to use and convert some stuff. https://footprinthero.com/milliamps-to-amps-conversion-calculator

2 of 3

You would have a much easier project if you used a 5V light strip and an off the shelf power bank with USB connector. Without knowing what lights you want to use, it's hard to know how long the battery will last exactly, but 1h is not hard to achieve for a lightbox because it simply won't use much power.

r/led on Reddit: Recommendations on powering 12v light strips with a 5V battery pack

June 4, 2022 -

Hello friends :)

Before I start please know that I don't know anything about power, volatge or amps, so apologies if some of these questions don't make complete sense :)

I'm thinking of adding some LED strips to a costume for a party that's coming up and needed some advice. I already played around with adding two Govee 5v strips to a costume and powering them with my 20100 mAh Anker battery and it's been working really well.

However, these 5v strips are pretty short (6ft each - assuming it's because the 5v battery can only power so much strip?) so I'm thinking of using a longer strip, but anything longer than 6ft seems to be 12v.

I found this DC 5V to DC 12V USB Voltage Step Up Converter Cable online that seems like could do the trick powering a 12v strip from my 5v battery, and was wondering the following:

Is this even a safe thing to do? Does that adapter look sketch? I'd be keeping the battery pack in my pocket, most likely.. could it overload or anything like that? I got that battery pack 4 years ago so it's starting to date a little.
How fast would this drain my battery pack when used? The battery pack outputs 4.8 amps and has two USB ports. The 12v light strip shows 18watts, but nothing in terms of amps.

If the above isn't the right way to go, I also found some 12v battery packs (this or this), but those are definitely bigger and a bit more expensive.

Any reason to believe this would be safer or more recommended than the above?

Now let's say I wanted to power two of those 12v strips.. could I use two 5v > 12V adapters on the 5v battery pack or is that really pushing it?

Any other advice on what to do or not to do?

Thanks!!

| powering 12v light strips with a 5V battery don't do that. use 5V strips. | don't know anything about power, volatge or amps You're going to want to start there. Learn about voltage, amps, resistance, watts, and how they relate to each other before starting a project that could start a fire - especially a wearable project. Youtube is great. Adafruit has a ton of tutorials on basics. This is a great place to start: https://learn.adafruit.com/adafruit-neopixel-uberguide/the-magic-of-neopixels | adding some LED strips to a costume This is a terrible idea, and very difficult to do for a first project. I say that as someone who professionally puts LEDs in wearables, strips are the worst idea for wearables. They just don't bend the right way and will eventually break. Much better to use some RGB fairy lights for wearables. This is what all the cool kids are using these days: https://www.amazon.com/gp/product/B09FKX5C1Q/ | 6ft each - assuming it's because the 5v battery can only power so much strip? They are 6ft because Govee cut them to 6ft. You should be able to power 15ft or more of 5V strip from a single USB port on a good power bank. Try to find a power bank with 3A. Lots of them are only 2A per port, or even 1A per port. | anything longer than 6ft seems to be 12v Keep looking, there's tons of 5V longer strips. The ones I sent above are 32 ft. BTF-LIGHTING on amazon has a bunch that are 15ft: https://www.amazon.com/dp/B01CDTEJBG/ | I found this DC 5V to DC 12V USB Voltage Step Up Converter Cable Again, a terrible idea for multiple reasons. converting 5V to 12V will half your amp output, so you can run fewer lights and less brightness for less duration. 12V strips in general is less energy efficient and uses more power than 5V strips. I would not use 12V if running from a battery, especially for wearables. 12V would be for around the house running off a wall outlet. | Is this even a safe thing to do Things are only as safe as you make them, you need to take some personal responsibility here. If you don't know, assume it's not safe. | Does that adapter look sketch? Yes | I'd be keeping the battery pack in my pocket, most likely.. could it overload or anything like that? If it's from Anker it will have tons of protection against overdischarge etc. that will turn off before it explodes. If it's a cheap no name brand from China it is entirely possible that it will catch fire and explode in your pocket if you don't know what you're doing. | How fast would this drain my battery pack when used This is difficult to calculate, for more reasons than I can get into here. It depends on how bright you run the lights, how many LEDs are on at a time, and what color they're showing. | The battery pack outputs 4.8 amps and has two USB ports. The 12v light strip shows 18watts, but nothing in terms of amps. You should google ohm's law and watt's law and memorize those equations. They're not hard it's like A times B equals C. Watts = Volts x Amps. so 18W = 12V x ?A ?A = 18/12 = 1.5A Please note that the 4.8 A rating on that power bank is combine between 2 ports, but each port has a limit of 2.4A. Do not try to pull 4.8 A from a single port, or it will shut itself off (or explode).

2 of 2

Max current: 0.6A; You're limited to 7W, so not many LEDs per step up converter. Your battery pack can theoretically do 2x strips of 2.4A, so you could get 2 of them and get up to 14W (split into two strips of 7W each). FWIW, no idea about the govee brand specifically, but longer 5V strips are easy to find, or you could connect two shorter strips.

r/18650masterrace on Reddit: 12V Led strip powered with 18650 battery pack

December 6, 2022 -

As the title says, I want to build a 12V led strip powered by a 18650 battery pack. I was thinking about a 1S6P, TP4056 as a "BMS", solar panel to charge it and a buck-bust converter to increase the voltage output.

But during my planning I thought, what would be better, 1S6P, 2S3P or 3S2P? I would appreciate any help with this and if anyone have any recommendations plis help.

Pd: the lights are going to be on my apartment balcony, so I'm planning to do this build as waterproof as I can.

It's always more efficient to directly use the voltage available rather than stepping it up or down. For longer runtime I'd use a 3S or 4S configuration.

2 of 3

I have a few setup as single parallel and 3s, the pros to a single parallel string + boost is they don't dim out as the cells discharge, but I get a little more run time with 3s due to better efficiency of not using the boost, not to mention current will drop with voltage when using LEDs resulting in even more run time, I personally prefer 3s.
