Go Power! 250Ah Lithium Iron Phosphate Solar Battery Delivers Nearly Double the Capacity So That You Never Run Out of Power When It Matters Most
Whether you're deep in the backcountry with no hookups in sight, parked at a remote job site, or riding out a grid outage at home, one truth holds: power is non-negotiable. The Go Power! 250Ah Lithium Iron Phosphate Solar Battery (Model GP-LIFEPO4-250) was engineered for exactly these moments delivering the kind of high-capacity, long-lasting energy storage that lets you stay comfortable, productive, and connected no matter where life takes you.
Built specifically for mobile and off-grid applications, this 12.8V deep-cycle LiFePO4 battery is a direct replacement for Group 31 lead-acid batteries and integrates seamlessly into existing 12V power systems. The result? More usable power, faster charging, an impressively long service life, and the confidence that your system will perform on demand day after day, season after season.
At Outbound Power, we specialize in portable and backup power solutions for homeowners, RVers, off-grid adventurers, and mobile businesses and we stand behind every product we carry. The Go Power! GP-LIFEPO4-250 is one of the most capable, intelligently engineered deep-cycle lithium batteries available for 12V mobile and backup applications, and its 10-year warranty speaks directly to the quality built into every unit.
Go Power! 250Ah Lithium Iron Phosphate Solar Battery Features
This battery holds nearly double the power of regular batteries.
At 250Ah, you get significantly more usable energy than a standard lead-acid battery. That means longer run times for your RV, cabin, or worksite without constantly worrying about recharging. More power stored equals more freedom every day.
It charges back up fast so you spend less time waiting.
The GP-LIFEPO4-250 can fully recharge in as little as 2.5 hours. Whether you're using solar panels or a shore charger, you get back to full power quickly. Less downtime means more time doing what matters most to you.
A smart built-in system keeps your battery safe at all times.
The built-in Battery Management System (BMS) watches over voltage, temperature, and current around the clock. It automatically shuts off if something goes wrong, protecting both your battery and your connected devices from damage.
It works perfectly with all Go Power! solar gear you already own.
No need to replace your existing setup. This battery connects seamlessly with all Go Power! solar panels, inverters, and charge controllers. It's a simple drop-in upgrade that makes your whole system work better together right away.
You can connect up to four units for a bigger power bank.
Need more capacity? Link up to four GP-LIFEPO4-250 batteries in parallel for up to 1,000Ah of storage. This makes it easy to scale your power system as your energy needs grow over time.
It lasts through thousands of cycles so you replace it far less often.
Rated for approximately 3,000 charge cycles, this lithium battery outlasts standard AGM batteries by years. You save money long-term because you are not replacing your battery bank nearly as often as you would with lead-acid options.
A 10-year warranty gives you real peace of mind for the long haul.
Go Power! backs this battery with a 10-year prorated warranty. That kind of coverage tells you exactly how confident the manufacturer is in their product. Buy it once, rely on it for years, and enjoy that confidence every single day.
