Simple Power System Build for Your Next Adventure

How to Build a Lightweight, Connected, and Cold-Ready Power System Using Expion360’s Group 27 100Ah SmartTalk™ and VHC™ Battery

When you're planning your next off-grid trip, the last thing you want is power failure. Whether you're overlanding, vanlifing, or camping deep in the wild, a dependable battery is the foundation of your power system. And it all starts with one smart, rugged solution: the Expion360 Group 27 100Ah SmartTalk™ and VHC™ LiFePO₄ Battery.

 

 

Start With Your Power Budget

Before wiring anything, ask yourself:
What are you powering each day?

  • A 12V fridge to keep food fresh

  • LED lighting for evenings

  • A water pump for showers and sinks

  • Phone and laptop charging

  • Cooking gear, blenders, or power tools

Knowing your daily energy needs (in watt-hours) helps you size your system correctly. A great starting setup includes:

This combo gives you intelligent battery management, solar charging support, and a solid base to expand later.

 

 

Go Lightweight & Long-Lasting

Why ditch lead-acid? Because it’s heavy, short-lived, and not built for life on the move.

Expion360’s LiFePO₄ batteries deliver:

  • Up to 10× more cycle life than traditional batteries

  • Lightweight build perfect for vans, trailers, and off-road rigs

  • Compact footprint with power-packed performance

  • 12-year warranty – built to go the distance

The Group 27 100Ah SmartTalk™ and VHC™ Battery is the ideal entry point: full-featured, rugged, and ready for real-world adventure.

 

 

Charge Anywhere

Stay powered no matter where the trail leads. With the right gear, your system can charge from:

Pair your system with dual SmartSolar MPPT 75/15 controllers to handle both fixed and portable solar input. That’s ultimate flexibility.

 

 

Stay Connected

Gone are the days of guesswork and voltage meters. With SmartTalk™ Bluetooth, you get real-time data from your battery straight to your smartphone. Monitor:

  • State of charge

  • Voltage and current

  • Battery temperature

  • Cycle history and more

Add a Cerbo GX + Touch 50 display for full-system visibility and control. It’s like a mission control center for your off-grid setup.

 

 

Cold Weather Ready

Winter adventures shouldn’t mean power problems. Cold can kill performance—or worse, damage your batteries.

That’s why the VHC™ (Vertical Heat Conduction) tech in Expion360 batteries matters. It offers:

  • Active self-heating to keep cells warm and chargeable

  • Temperature protection for longevity

  • Confidence to run your rig in sub-freezing temps

Whether you’re skiing, snow camping, or traveling in colder climates, Expion360’s heated lithium batteries keep your system alive.

 

 

Mount It Securely

Off-road terrain puts your gear to the test. Make sure your power system is secure, safe, and serviceable:

  • Use rugged battery trays for mounting

  • Protect wires with proper routing and fuse blocks

  • Keep components accessible for quick service

Your system should be as ready for the trail as your tires are.

 

 

Final Thoughts

Building a simple power system doesn’t mean sacrificing performance. With the Expion360 Group 27 100Ah SmartTalk™ and VHC™ Battery, you get:

  • Smart Bluetooth monitoring

  • Cold-weather capability

  • Long cycle life
