Powering Up: How to Connect 3 Batteries for 24V Gaming and Creating

As a gaming and content creation enthusiast, I‘m always looking to push the envelope when it comes to the latest hardware for the best performance. And that increasingly means moving to higher voltage systems that can provide more power and efficiency. But consumer grade gear typically maxes out at 12V ratings.

So what‘s an enterprising gamer to do when you want to build a 24V monster rig or run a host of accessories? Simple – use 3 standard batteries and connect them together into one powerful 24V battery bank!

Why You Need 24 Volts

Higher voltage unlocks potential. With 24V you can have brighter custom LED lighting, high-torque motors for motion rigs, faster charging for accessories and the headroom for expansion.

Some specific examples would be:

• LED video walls with 1000s of addressable pixels
• Electric motion platforms for racing simulators
• Battery banks to run mains-voltage mini-fridges for snacks and drinks!
• Powering steampunk MechWarrior cosplay EVA foam armor
• Faster charging USB-C Power Delivery battery packs for phones/laptops

So 24V opens up options that lower 12V systems struggle with due to current limits. Let‘s check out how to combine 3 batteries to get there!

Step-by-Step Guide

You will need:

• 3x 12V Lead Acid or Lithium Ion batteries of equal capacity
• DC terminal connectors and cabling
• Battery tray (optional)

Steps:

1. Identify your positive (red) and negative (black) terminals
2. Connect positive terminal of Battery 1 to negative terminal of Battery 2
3. Connect positive terminal of Battery 2 to negative terminal of Battery 3
4. Connect load between positive of Battery 1 and negative of Battery 3

Diagram:

With the batteries chained positive to negative terminal, their voltage adds up but capacity remains the same. So 3x 12V 10Ah provides 24V 10Ah.

Key Design Considerations

• Match battery chemistry – e.g. all lead acid or lithium ion
• Match capacities to avoid over discharge
• Buy from reputable suppliers to ensure battery quality
• Start with fully charged batteries
• Allow airflow for cooling if encased
• Use appropriately rated cabling, fuses/breakers
• Invest in a Battery Management System (BMS) for lithium batteries

Charging and Maintenance

• Charge the entire bank as one unit using a compatible 24V charger
• Periodically full charge and equalize individual batteries
• Check voltages of each battery under load
• Watch for bulge/overheating and unusual voltage drops indicating aging battery
• Keep terminals clean and tightened

Expanding Capacity

While series connections get higher voltage, parallel connections increase capacity. Some options:

• Start with higher capacity 12V batteries
• Add additional matched batteries in parallel groups, then connect groups in series
• Opt for lithium batteries for best density by weight or volume

Here is an example 6x battery setup with doubled capacity:

The Clear Benefits of 24V

Higher voltage has physical advantages due to lower current for an equivalent power output.

So 24V systems can use thinner, cheaper cabling for equivalent power since current is halved. And cable transmission losses are slashed due to the higher voltage.

No wonder 24V traction and motive systems are popular for electric vehicles and industrial equipment. And now even gaming gear!

Recommended Batteries

While any 12V batteries can be used, these options provide good performance at a reasonable cost:

Lithium batteries are superior but cost more. Consider as an investment into your passion!

Closing Thoughts

Connecting 3 batteries to achieve 24V may sound intimidating but is actually straightforward. Take reasonable precautions and the series battery bank will perform reliably.

Now you can stop compromising and power that ultimate gaming and creating gear! Build a 24V foundation for your dream projects today.
