This design isn’t just space-saving, it simplifies maintenance and ensures stable performance even under high-demand conditions.
Built-in 100A BMS for Comprehensive Protection
At the core of this battery lies a built-in 100A BMS (Battery Management System) that protects against overcharge, over-discharge, short circuit, and temperature extremes. The BMS constantly monitors voltage and current to maintain system safety and stability. It automatically stops charging below 32°F and discharging below −4°F to protect the cells in harsh weather. This advanced safety layer ensures reliable power even under challenging off-grid conditions.
Smart Monitoring with LCD Display and Bluetooth App
The Vatrer 48V 100Ah model includes a built-in LCD touchscreen for on-site data display and a Bluetooth App for remote control. Users can monitor battery charge level, voltage, current, and temperature in real time. Three intuitive display pages allow easy visualization of system status, and mobile connectivity means you can check your solar lithium battery performance from anywhere. This smart interface brings transparency and control to your energy management system.
Easy Installation and Lightweight Design
Thanks to its SPCC steel shell and rack-mounted form factor, installation is simple and flexible. The battery can be installed horizontally or vertically, depending on available space. At roughly 70% lighter than lead-acid alternatives, it’s easier to handle and requires less physical support. The compact rack structure also reduces installation time, making it ideal for modular setups in homes, RVs, or commercial energy systems.
Scalable Energy Expansion up to 51.2kWh
For larger applications, this battery supports parallel connections of up to 10 units, expanding the total capacity to 51.2kWh and output to 51.2kW. This modular scalability makes it perfect for small businesses, farms, or off-grid homes that plan to grow their solar system over time. The system’s flexibility allows you to start small and scale your storage capacity as your energy needs increase.
Versatile Charging Options
The Vatrer 48V 100Ah server rack lithium battery supports three efficient charging methods:
- LiFePO4 charger (58.4V 20A) — full charge in about 5 hours.
- DC-to-DC charger (30A) — full charge in about 3.3 hours via generator or alternator.
- Solar charging (48V MPPT, >1500W) — converts clean solar power into stored energy efficiently.
This flexibility ensures consistent battery charge even when one energy source isn’t available, making it ideal for remote or mobile setups.

TECH SPECS
Have two of such batteries for about a year. Bought two more to increase storage. Happy about the quality and stability of the product. With 4kw over and a 5kw inverter, I have an off grid power system for many appliances in my home.
I am off grid with 6000 w solar easily charging these batteries, two electric golf carts, home and garage and water well.
This is fantastic compared to my old 32 lead acid golf cart batteries
Very nice battery
This my third. So far all have performed great.
Arrived quickly. Well packaged. Exactly as advertised.
FAQs
Yes. The Vatrer 48V 100Ah lithium battery is fully compatible with most 48V solar systems using MPPT controllers and inverters. It can also work alongside solar panels rated above 1500W. If your system uses other battery types, make sure the charging voltage and current match LiFePO4 standards before connecting.
A server rack lithium battery is designed for modular scalability and easy maintenance. Unlike wall-mounted batteries, you can stack multiple units vertically in a cabinet to create a larger energy bank, ideal for off-grid systems, farms, and businesses that may need to expand later. It’s also easier to replace or add modules without rewiring the entire setup.
Absolutely. The Vatrer 48V 100Ah battery provides reliable power for both residential and light commercial applications. When combined with an inverter, it can power critical loads such as lighting, communication systems, computers, or small machinery during grid outages, making it a great fit for both homes and small business energy storage.
Under normal operating conditions (20–80% daily usage), you can expect a service life of over 10 years, thanks to its 5,000+ cycles at 100% depth of discharge (DoD). Occasional shallow cycles and proper storage can extend its lifespan even further, providing dependable performance long after a typical lead-acid battery would need replacement.
It’s best to install the battery indoors or in a weather-protected cabinet. While the built-in 100A BMS includes low-temperature and overheat protection, long exposure to extreme heat or cold can reduce efficiency. For outdoor installations, use a ventilated and insulated rack enclosure to maintain temperature stability.
No regular maintenance is required. Unlike lead-acid batteries, which need water refilling and corrosion checks, this solar lithium battery is maintenance-free. The BMS automatically balances cells and protects against overcharge, over-discharge, and short circuit conditions. However, it’s recommended to periodically check the connection terminals for cleanliness and tightness.
When connected in parallel, each battery’s data can still be monitored through its Bluetooth App. For larger-scale systems, the Vatrer App enables centralized monitoring of the system, supporting the tracking of voltage, temperature, and battery charge status across multiple rack units, ideal for solar energy storage systems above 10kWh.
Yes, but within limits. Each unit can handle up to 100A continuous discharge, suitable for most residential inverters and off-grid setups. If your system requires higher output, such as 200A or more, you can parallel up to 10 units for increased power output (51.2kW) and total energy storage of 51.2kWh.
Before installing, make sure to fully read the product manual. Charge the battery to 100% using a LiFePO4-compatible charger (58.4V 20A) to balance the internal cells. Avoid connecting different battery brands or voltages in the same circuit. For best results, install it in a clean, dry area and ensure proper grounding for stable performance.
Vatrer focuses on high-quality server rack lithium batteries with Grade A LiFePO4 cells, precise 100A BMS protection, and user-friendly smart monitoring.
