The Vatrer 48V 100Ah heated lithium battery is a rack-mount LiFePO4 unit with a built-in 100A BMS, self-heating for cold-weather charging, and Bluetooth monitoring via app and LCD. It delivers up to 5120W continuous output and is rated for 5000+ cycles at 100% depth of discharge. It suits off-grid and backup solar setups that see freezing temperatures. Compared with unheated server-rack batteries, it adds cold-weather charging but costs more; the app and display are useful extras that some rivals lack.

Owners appreciate the built-in heating for winter charging and the clear app monitoring. Some find the Bluetooth connection finicky and the display basic. Overall, it is seen as a solid cold-weather battery.
This is a 48V (51.2V) 100Ah LiFePO4 lithium battery for solar energy systems. It is built with Grade A cells and has a built-in 100A battery management system (BMS), so it needs no extra wiring. The BMS protects against low and high temperature, over-discharge, overcharge, over-current and short circuit.
A built-in heating function starts when the temperature drops below 32°F (0°C) to prepare the battery for charging. Heating stops once the battery reaches 41°F (5°C), and normal charging resumes. An LCD screen and a Bluetooth app show real-time current, voltage and temperature, let you control charge and discharge modes, and show the voltage difference between the internal cells.
The battery is maintenance free and non-spill. It has carry handles for lifting and moving. It can replace or upgrade a traditional lead-acid battery, and it is 70% lighter than lead-acid alternatives. Up to 10 units can be connected in parallel. It suits RVs, campers, boats, camping, off-grid and home energy systems, and backup power.
