So whether you're powering your RV, home backup system, or off-grid setup, you can enjoy dependable energy with added peace of mind. More Usable Power, Less Weight to Carry Upgrading your battery shouldn’t mean adding more weight. Compared with traditional lead-acid batteries, this TEMGO LiFePO4 battery delivers 300Ah of capacity while weighing about one-third as much. That makes it easier to move, install, and store—especially when space and weight matter in an RV, boat, or off-grid system. With 100% usable capacity, 5,000+ cycles, and up to 10 years of service life, you can get more from your battery over the long run without the bulk of lead-acid. Know Your Battery at a Glance No more guessing when your battery needs a recharge. Connect your phone through Bluetooth by scanning the QR code on the battery, then use the TEMGO App to keep track of important information in real time. You can check the voltage, current, remaining capacity, and temperature from your phone or the built-in touchscreen. It’s an easy way to see what’s happening with your battery and catch unusual conditions before they become a bigger problem.

This 12V 300Ah battery supports up to 4S4P configurations, giving you the option to add more batteries when you need more storage or output. Start with what works for you today, then expand your setup for bigger energy demands such as refrigerators, washing machines, air conditioners, and other appliances. It’s a flexible way to build backup or off-grid power at your own pace. Charge Your Way Whether you’re parked at home, traveling in your RV, or spending time away from the grid, you have more than one way to recharge. This battery can be charged using an AC charger, solar power, or a generator. Use solar energy when conditions are right, or switch to an AC charger or generator when you need a dependable backup.
