12V 100Ah LiFePO4 Lithium Battery


12.8V 100Ah LiFePO4 Battery: The Ultimate Power Upgrade for Your Adventures
Are you still struggling with heavy, short-lived lead-acid batteries? It’s time for a change. At Haineng Energy, we’ve engineered this 12.8V 100Ah LiFePO4 battery to be the heart of your power system—whether you’re out at sea, living off-grid in an RV, or building a sustainable home energy setup.
Why Choose This Battery? (The Real Benefits)
Weight That Won't Hold You Back: At just around 11.5kg, it’s less than half the weight of a traditional AGM battery. Your RV will thank you for the better fuel economy, and your back will thank you during installation.
Power That Lasts a Decade: While standard batteries give up after 300-500 cycles, our Grade A LiFePO4 cells deliver 4,000 to 6,000+ deep cycles. That’s over 10 years of reliable daily power.
Battle-Tested Waterproofing (IP67): We know the environment can be harsh. Our IP67-rated casing is built to withstand salt spray on a boat or heavy rain in the wild, keeping the internal electronics bone-dry and safe.
