Looking forward to using it this camping season

Looking forward to using it this camping season. It should extend my off grid camping.

Lithium for our RV

The LCD screen is mounted on the top of the battery box which makes it totally unusable when the battery is mounted on a shelf in the RV. I've ordered two more displays and will run the pigtail out a hole in the side of the box and mount them on the side of the bat box. Internal construction looks excellent.

Works as expected

Recently installed, so not enough time to thoroughly evaluate. Pleased with the metal case and bluetooth. Cell balance perfect (within .1+ volt of each other).

Great battery… lousy service!

So far, I certainly don’t have any complaints with the battery’s performance, but I certainly do with the factory support.

In one part of the battery’s operation, you have to apply for permissions, which they give you a link to do. Two months later, they refuse to give it to me. They also are not very forthcoming with questions about the system. I think I’ll be switching to Vatrer batteries.
FAQs

How does the self-heating feature benefit a 12V 460Ah LiFePO4 Battery?
The built-in heating system helps prepare the 12V 460Ah Lithium Battery for charging in cold conditions. When the battery temperature drops below 0°C (32°F) during charging, the BMS activates the heater automatically.

Does the heater stay on continuously?
No. The heating function is automatically managed by the BMS. It starts when the battery is below 0°C (32°F) while charging and stops once the battery reaches approximately 5°C (41°F).

Is this 460Ah Battery suitable for winter RV and camping use?
Yes. The combination of 5,888Wh of energy capacity and automatic self-heating makes this 12V 460Ah Battery suitable for RVs, campers, off-grid camping, and other applications exposed to cold weather.

How much energy can the 12V 460Ah Lithium Battery store?
The battery is rated at 12.8V and 460Ah, providing approximately 5,888Wh (5.888kWh) of nominal energy for long-duration power storage.

Why does a 12V LiFePO4 Battery have a 12.8V nominal voltage?
Four 3.2V LiFePO4 cells connected in series produce a 12.8V nominal voltage. The battery is classified as 12V because it is designed to operate in standard 12V systems.

How much current can this 12V 460Ah Battery handle?
The integrated 300A BMS supports high-current operation, with up to 3,840W of continuous output for compatible 12V loads.

What charging setup is recommended for this 12V Lithium Battery?
Use a LiFePO4-compatible charger with a 14.2–14.6V charging voltage. The recommended charging current is 92A for the 460Ah capacity.

Can I view the battery data remotely?
Yes. Bluetooth connectivity allows the Temgo App to display battery information on a compatible smartphone, while the built-in LCD touchscreen provides convenient local monitoring.

What protection does the BMS provide on this 12V 460Ah LiFePO4 Battery?
The 300A BMS monitors battery operation and provides protection against overcharge, over-discharge, overcurrent, overheating, and short circuits. Cell balancing also helps maintain consistent battery performance.

How long is the service life of this 460Ah Lithium Battery?
The battery is designed for 5,000+ charge cycles and up to a 10-year service life under suitable operating conditions. Actual performance depends on usage, temperature, charging practices, and depth of discharge.

Can I expand a 12V 460Ah Self-Heating Battery system?
Yes. Multiple 12V 460Ah LiFePO4 Batteries can be connected in series and parallel to increase system voltage and total capacity. Follow the manufacturer's recommended configuration when expanding the battery bank.
