200A BMS for Powerful, Reliable Protection
Powerful appliances demand more from a battery. That’s why this TEMGO 12V 300Ah LiFePO4 battery is equipped with a 200A BMS to keep a close eye on battery performance while you use it. The built-in protection system helps guard against overcharging, over-discharging, excessive current, short circuits, high voltage, and high temperatures. 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.


Build Your System as Your Needs Grow
You don’t have to build a large power system all at once. 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. That flexibility makes it easier to keep your power system ready wherever you go.


One Battery for Everyday Adventures
From weekend trips to backup power at home, this 12V 300Ah / 3840Wh LiFePO4 battery is built to keep your essential equipment running. With up to 2560W of continuous output, it can power everyday loads such as refrigerators, lights, and electronics while providing dependable energy for RVs, boats, fishing trips, solar systems, and off-grid living. When you need reliable power away from the grid, TEMGO gives you the capacity to stay powered for longer.
