Automatic Heating Keeps Winter Charging on Track
In an unheated garage, shed, or off-grid cabin, freezing temperatures can stop a LiFePO4 battery from charging normally. When charging power is connected, this Vatrer heated LiFePO4 battery automatically checks the battery temperature. At 32°F or below, incoming charging power goes to heating first and the cells remain out of charge. Once the temperature rises above 41°F, heating stops and normal charging begins. You do not need to add a separate heating pad or manually warm the battery before charging in cold conditions.


5.12kWh of Power with Smart BMS Protection
This 48V 100Ah lithium battery stores 5.12kWh of energy in one rack-mount battery for solar storage, home backup, cabins, and other 48V systems. Its built-in 100A smart BMS manages charging and discharging while protecting the battery from overcharge, over-discharge, over-current, short circuit, and unsafe temperatures. For a 48V setup, that gives you one integrated battery instead of building a bank from multiple smaller batteries.




Grade A Cells Built for Regular Cycling
EV Grade A LiFePO4 cells are built for the repeated charging and discharging that comes with solar storage and backup use. This Vatrer 48V 100Ah LiFePO4 battery is 5,000+ cycles, making it well suited to systems that run regularly throughout the year. If you are replacing AGM or flooded lead-acid batteries, LiFePO4 chemistry also cuts down on routine battery maintenance and frequent replacement.


Start with One Battery and Expand as Needed
A single battery gives you 5.12kWh of storage, while support for up to 10 batteries in parallel lets the system grow with higher backup demand or additional solar capacity. If you later add more household loads or want longer backup time, you can add batteries without replacing the storage system you already installed. The 48V server rack battery format also keeps each added battery within the same rack-based setup.


Monitor the Battery at the Rack or Remotely
The built-in touchscreen shows battery information directly at the rack, while Bluetooth provides local monitoring through the mobile app. WiFi lets you view battery status remotely and supports OTA firmware updates without being near the installation. The battery also supports communication with a wide range of inverter models, allowing battery and inverter data to work together within the same solar or backup system.


Recharge from AC Power Solar or a Generator
Use AC charging when grid power is available, solar charging during normal off-grid operation, or a generator when solar production is low or utility power is unavailable. With a 20A LiFePO4 charger, the battery can recharge in about five hours. At a cabin or during an outage, you still have another way to recharge when weather changes or one power source is unavailable.




Fit the Battery into Your Available Space
The rack-mount enclosure keeps multiple batteries together in one installation, while the SPCC metal housing gives the battery a solid enclosure for everyday use. The battery can be positioned horizontally or vertically, making this server rack LiFePO4 battery easier to place in garages, utility rooms, equipment spaces, and off-grid installations where rack height or floor space may limit the layout.


Build Your 48V Storage System for Colder Conditions
Add this Vatrer battery to a 48V solar or backup system that needs to keep charging through colder seasons without a separate battery-heating setup. Local and remote monitoring make it easy to follow battery status, while the expandable rack design lets you start with the storage capacity you need now and add more later as your energy needs grow.

FAQs
When charging power is connected, our battery checks its temperature automatically. At 32°F or below, the charging input is used to warm the battery first instead of charging the cells. Once the temperature rises above 41°F, heating stops and charging begins automatically. The heating function requires more than 5A of charging current.
No. The automatic heating function uses incoming charging power rather than continuously drawing energy from the battery itself. This helps preserve stored energy for your loads while still allowing the battery to prepare for charging in cold conditions.
Yes. This battery is designed for installations where the battery may experience freezing temperatures, such as an unheated garage, shed, or seasonal cabin. When you reconnect a charger, solar charging source, or other suitable charging input in cold weather, the automatic heating process prepares the battery before charging starts.
A single battery stores 5.12kWh of energy. As a simple sizing reference, a 500W average load represents roughly 10 hours of theoretical runtime, while a 1,000W load represents roughly 5 hours. Actual runtime will be lower after inverter losses and other system consumption, so use your normal average load rather than an appliance's peak wattage when estimating backup time.
The built-in 100A BMS corresponds to about 5.12kW at the battery's 51.2V nominal voltage. A 5kW inverter operating continuously near full output can therefore bring one battery close to its current limit, especially when conversion losses or load surges are included. For systems that regularly run heavy loads, adding batteries in parallel spreads the current across the battery system and increases available storage at the same time.
You can expand the system to as many as 10 batteries in parallel, increasing total storage from 5.12kWh to 51.2kWh. When building a larger battery system, we recommend using the same battery model and bringing the batteries to a similar state of charge before connecting them together. This gives each battery a more balanced starting point.
Each option serves a different monitoring need. The touchscreen lets you check battery information directly at the rack, Bluetooth connects the battery to the mobile app for local monitoring, and WiFi gives you remote access when you are away from the installation. WiFi also supports OTA firmware updates, so software updates can be handled without working directly at the battery.
Yes. We built inverter communication into the battery so it can exchange operating information with a wide range of inverter models used in 48V solar and backup systems. This allows the inverter and battery management system to coordinate battery information instead of relying only on voltage-based monitoring.
You can recharge it from AC power, solar, or a generator. A 58.4V 20A LiFePO4 charger takes about five hours for a full recharge under normal conditions. Solar can be paired with a 48V MPPT charge controller, while a generator can supply charging power through a suitable DC-to-DC charger, giving you more than one way to recover energy during outages or extended off-grid use.
Yes. Its 51.2V nominal voltage is designed for 48V systems, making it a practical upgrade from a 48V lead-acid battery bank. One 5.12kWh battery can replace the complexity of several smaller batteries while eliminating watering and equalization maintenance. Use a LiFePO4 charging profile rather than lead-acid charging settings so the system charges according to LiFePO4 requirements.
