DC12V Lithium Battery

9 products

DC12V lithium ion rechargeable batteries can provide low voltage 12 volts to power electronic devices such as LED strip lights. These 12 volt lithium batteries are ideal for portable lighting applications, allowing you to add a variety of mood lighting to your camping, picnic, patio activities, and for cars.

A DC12V lithium battery pack is the simplest way to run 12-volt LED strip lights when you don't have access to a wall outlet. These rechargeable, portable power supplies are perfect for temporary installations like trade show booths, event lighting, parade floats, or even adding accent lighting to vehicles and boats. For any project that needs to be self-contained and mobile, a battery is a cleaner solution than running long extension cords. SuperLightingLED provides a complete range of 12V lithium batteries, designed specifically for low-voltage lighting applications.

Our product system includes 9 distinct models, giving you a wide power range to choose from. Capacities start at 3Ah (Amp-hours), or 36 Watts, which is enough for a small accent piece, and go all the way up to 60Ah, or 720 Watts, for powering substantial, multi-strip installations for hours. Every unit is a self-contained system with Lithium Iron Phosphate (LiFePO4) cells and built-in protection circuits, delivering stable 12V DC power through a standard DC barrel jack connector.

What is a 12V Lithium-Ion Battery for LED Lights?

A 12V lithium-ion battery pack for LED lights is a self-contained, rechargeable power source that combines the battery cells, a safety management circuit, and output connectors into one portable unit. Unlike a raw battery, these packs have an internal Battery Management System (BMS) that protects against over-charging, over-discharging, and short circuits, which is critical for safety and battery life. They are designed to be a direct replacement for a plug-in 12V plastic shell power adapter, allowing you to use 12V LED products anywhere.

DC12V Lithium Battery: Features and Powering Options

Our portable 12V lithium power packs are designed for straightforward use in mobile lighting projects. They integrate the core components you need to safely power LED strip lights away from an AC outlet. For a deeper look at battery-powered options, see our guide on using battery operated lights.

  • Wide Capacity Range: We offer 9 models spanning 3Ah (36W) to 60Ah (720W), letting you match the battery size precisely to your project's power draw and required runtime.
  • Simple Connection: Each battery features a standard 5.5mm x 2.1mm DC barrel jack for output. This allows for direct plug-and-play connection to many single color LED strips and accessories.
  • Integrated Safety BMS: An internal Battery Management System (BMS) protects the lithium cells from common issues like over-voltage, under-voltage, and short circuits, ensuring safe operation and protecting your investment.
  • Rechargeable System: Every battery pack is rechargeable and most models include a dedicated AC charger to replenish the battery.

How to Use Battery Powered LED Strip Lights

Using a battery to power LED strip lights is quite simple. First, you'll need to match the battery's capacity to the total power consumption of your LED strip to ensure you get the runtime you need. Once you have the right battery, you connect its DC output jack directly to the strip's power input connector. If you want to add brightness and color control, a controller can be wired between the battery and the strip. When the lights dim or go out, you just disconnect the strip and plug the battery into its charger.

Limitations of a Portable 12 Volt Battery for LED Lights

While these batteries are incredibly useful, there are a few practical limits to keep in mind. All models in this category are rated IP20, meaning they are not waterproof and are intended for use in dry locations only. For outdoor or wet applications, you'd need to place the battery inside a suitable waterproof enclosure or use a hardwired IP67 waterproof 12V power supply instead. Finally, remember that higher capacity batteries have longer charge times, so plan accordingly for your events.

Frequently Asked Questions About DC12V Lithium Batteries

Got a question about running your LED strips on the go? I've been answering these for 12 years. Here are the things people ask most.

It's a portable, rechargeable power source for any 12V DC device, especially LED strips. You charge it at home, then take it anywhere you need light without a wall socket. It's perfect for event lighting, camping, trade show booths, or adding lights to a vehicle. Unlike a standard plug-in power adapter that needs AC mains, this gives you total freedom.

It's all about the Amp-hours, or 'Ah'. First, find the total wattage of your LED strip. Let's say your whole setup uses 60 watts. Divide watts by volts to get amps: 60W / 12V = 5 Amps. If you want it to run for 4 hours, you need 5 Amps × 4 Hours = 20 Ah. I always tell people to add a 20% buffer, so I'd grab a battery that's at least 24Ah to be safe.

It's usually very simple. Our 12v lithium battery packs have a standard 5.5mm x 2.1mm DC barrel connector on the output. Most single-color LED strips have a matching female plug, so it's just plug-and-play. If you want to add a switch, you can easily wire an in-line DC switch between the battery and the strip. You can see the whole process in our guide on connecting strips to power.

Absolutely. Any device that runs on 12V DC and stays within the battery's maximum current rating is fair game. We see customers using them for small water pumps, DIY electronics projects, portable fans, and even some CCTV cameras. At the end of the day, it's just a stable, portable 12V DC source.

You should expect somewhere between 500 and 800 full charge-and-discharge cycles before you'll notice a significant drop in its total capacity. For the longest life, try not to run it completely flat every time you use it. Also, don't store it for months on end either fully charged or fully empty — about a 50% charge is the sweet spot for long-term storage.

Not at all, and you should never swap them. A car battery is lead-acid, designed to deliver a massive surge of power for a few seconds to start an engine. Our 12v lithium battery packs are made for deep, steady discharge over many hours. They're also much lighter, safer for use indoors, and have a built-in Battery Management System (BMS) to protect against faults.

Yes, these units support what's called pass-through charging. You can have the charger plugged into the battery and have the battery powering your lights at the same time. This is really useful for semi-permanent setups where you want the battery to act as a backup in case the mains power goes out.
