Epoch Batteries 12V 172Ah (2.20kWh) Dual Purpose Essential Series Combines 1,000 CCA Cranking Power With Deep-Cycle Endurance for Dependable Energy Whether You're on the Water, Road, or Off-Grid
Most power users are forced to make a compromise: carry a dedicated starting battery and a separate house battery, eating up precious space and adding weight or accept that one battery will always be working harder than it should. The Epoch Batteries 12V 172Ah (2.20kWh) Dual Purpose Essential Series eliminates that trade-off entirely. Built on proven LiFePO4 lithium iron phosphate chemistry and packed into a rugged Group 31 form factor, this is a single battery that delivers a genuine 1,000 cold cranking amps (CCA) for reliable engine starts and up to 172 amp-hours of clean, sustained deep-cycle capacity for all the gear, appliances, and electronics that make your adventure or your workday actually work.
Whether you're cranking a 250-horsepower outboard offshore, powering the slide-outs and rooftop AC in your Class A motorhome, keeping lights and refrigeration running at a remote job site, or running a hybrid solar-battery backup at home, this 12V 172Ah LiFePO4 battery is engineered to handle all of it without complaint. And it does so with Bluetooth monitoring built in, an IP65 waterproof rating, and an industry-leading 11-year manufacturer warranty to back it up.
At Outbound Power, we specialize in exactly this category of product portable, backup, and off-grid power solutions for people who depend on their gear. We stock the Epoch Essential Series because we've vetted it, and we stand behind it. If you have questions about compatibility with your existing charge controller, inverter, charger, or solar setup, our team is here to help you get it right the first time.

One Battery That Starts Your Engine and Runs Your Gear

Fires Up Engines as Big as 250 Horsepower Without Hesitation
With 1,000 cold cranking amps, this battery delivers a strong burst of power that starts large outboard motors instantly. Whether it's cold outside or you've been running gear all day, your engine starts on the first try.
Check Your Battery Status Right From Your Phone
Built-in Bluetooth connects to a free app on any iPhone or Android. See your charge level, voltage, and temperature in real time. No need to pop open a hatch or dig behind a panel just to check your battery.
Water and Dust Cannot Slow This Battery Down
The IP65 rating means this battery is fully sealed against dust and protected from water jets. Rain, spray, splashes, or dusty job sites none of it gets inside. Your power stays protected no matter the conditions.
It Lasts Over 10 Times Longer Than a Regular Battery
