Whether you're keeping the lights on during a grid outage, running your RV air conditioner through the Nevada summer, powering tools on a remote worksite, or living completely off the grid in northern Montana power storage is only as good as the battery behind it.
The Epoch Batteries 48V 50Ah LiFePO4 Lithium Battery was built for people who cannot afford to be let down. With integrated heating technology, Bluetooth monitoring, IP67 waterproof certification, and an industry-leading 11-year manufacturer warranty, this isn't just a battery it's a long-term investment in energy independence.
At Outbound Power, we specialize in helping homeowners, RVers, off-grid enthusiasts, and mobile professionals build power systems they can genuinely rely on. Our team understands the nuances of 48V lithium systems from charge controller compatibility to BMS behavior under load and we're here to help you get it right the first time.
A built-in heater lets the battery charge safely in temperatures as low as -4°F. No more power failures on cold winter nights. It keeps working when most standard lithium batteries simply shut down and leave you stranded.
Connect to the free app on any iPhone or Android device. You can see voltage, charge level, and temperature in real time no guessing, no manual checks, just quick and easy battery monitoring from wherever you are.
With an IP67 rating, this battery is fully sealed against dust and can survive being submerged in water. Mount it outdoors, in an RV bay, or on a worksite without worrying about weather or rough conditions causing damage.
The built-in Battery Management System automatically stops overcharging, over-discharging, short circuits, and extreme temperatures. It works silently in the background so your battery stays protected every single day without any effort from you.
A typical AGM battery lasts around 400–600 cycles. This one delivers 3,500 or more. That means years of daily use before you ever need a replacement, saving you real money over the long run.
Epoch stands behind this battery with one of the longest warranties in the industry. Eleven full years of manufacturer coverage means you can install it with complete confidence and forget about battery problems for a very long time.
You can run up to four batteries in parallel or two in series. This makes it easy to expand your setup as your power needs grow perfect for off-grid homes, large RVs, or mobile businesses needing more energy storage.
Epoch Batteries provides a limited warranty policy, ensuring the absence of defects in materials, workmanship, and performance during the warranty period.
