Epoch 105Ah Lithium Battery "Essential Series" (12-Volt)

Epoch 12V 105Ah Heated Bluetooth LiFePO4 Battery

Reliable lithium power for DIY van builds, RVs, and off-grid systems.

The Epoch 12V 105Ah Heated Bluetooth LiFePO4 Battery is a powerful, compact lithium battery designed for mobile electrical systems where reliability and simplicity matter. With long cycle life, built-in heating for cold weather charging, and real-time Bluetooth monitoring, it’s an ideal upgrade for DIY van builders who want dependable power without constant maintenance.

Compared to traditional lead-acid batteries, lithium batteries like this one deliver more usable energy, faster charging, and dramatically longer lifespan—while weighing significantly less. That means more usable capacity for running fridges, lights, fans, and electronics in your van or RV without adding unnecessary weight to your build.

Built for Real Off-Grid Use

Many lithium batteries shut down or become damaged if you try to charge them in freezing temperatures. The Epoch Essential Series solves this with integrated internal heating, allowing safe charging in cold conditions as low as -4°F (-20°C). This makes it a great option for winter camping, mountain travel, and shoulder-season van life.

Know Your Battery at a Glance

With built-in Bluetooth, you can monitor your battery from your phone using the Epoch mobile app. Check state of charge, voltage, temperature, and current in real time so you always know how much power you have available.

For DIY builders, this removes the guesswork and makes it much easier to manage your electrical system while traveling or living off-grid.

Designed for Expandable Power Systems

The battery can be connected in series or parallel, allowing you to scale your system as your build grows. Start with one battery and add more later to increase capacity for larger inverter loads or longer off-grid stays.

Long Life, Low Maintenance

Lithium iron phosphate (LiFePO4) chemistry is known for its stability and durability. The Epoch 105Ah battery delivers 4,000+ charge cycles at 80% depth of discharge, meaning years of daily use before significant capacity loss.

A built-in smart battery management system (BMS) protects the battery from over-charge, over-discharge, short circuits, and temperature extremes to keep your electrical system running safely.
