Epoch Batteries 12V 300Ah (3.84kWh) Essential Series Features

It Charges Even When Temperatures Drop Below Freezing

The built-in internal heater warms the battery before charging starts. This means you can safely charge in conditions as cold as -4°F (-20°C) perfect for winter camping, cold-weather RVing, or off-grid living in harsh climates.

Check Your Battery Status Right From Your Phone

Bluetooth connects the battery to a free iOS or Android app. You can see voltage, charge level, temperature, and current in real time. No guessing, no extra gadgets — just quick, clear answers straight from your smartphone.

One Battery Holds Enough Power to Run Your Home Essentials

With 300Ah and 3.84kWh of usable energy, this battery can keep your lights, fridge, and key appliances running for hours. It stores roughly the same energy as three standard 100Ah lithium batteries in one compact unit.

A Smart System Protects Your Battery and Your Devices

The built-in Battery Management System (BMS) automatically prevents overcharging, over-discharging, short circuits, and overheating. It works quietly in the background so your equipment stays safe and your battery lasts as long as possible.

It Lasts Over 10 Years With Zero Maintenance Required

Rated for 4,000+ charge cycles, this battery keeps performing year after year without water top-offs, terminal cleaning, or equalizing charges. Just install it, use it, and let it work that's the whole routine.

Scale Up Your Power System as Your Needs Grow

You can connect up to four batteries in series (up to 48V) or in parallel (up to 1,200Ah). This makes it easy to start small and expand your energy storage later without buying an entirely new system.

It Is Backed by an 11-Year Manufacturer Warranty
