TECH SPECS
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
Really like the simplicity of these, works right into my system.
I’m using two of these connected to my Anker Solex F3800, soon to add a third. I have a 3.9 KW solar array, feeding a Victron solar charger controller, charging these batteries. They are perfect for my application as I don’t need the communication, just the Bluetooth and the display. The batteries are fully charged and discharged almost every day. No issues, they just work.
So far this battery is living up to every expectation… Time will tell, but so far… It's been just as advertised!
After 18 years, I swapped out my golf cart batteries for a tad bit more energy backup with (8) Vatrer batteries. These have been installed for two months and have exceeded my expectations. I purchased them last spring and just installed 2 months ago. My old batteries likely had 1 to 2 years left, but at age 75, I could not guarantee I had that much time left, and I wanted to reduce my battery maintenance of the lead acid batteries. Hence, I made this purchase from Vatrer. These batteries have wifi and a great visual display. Two years ago, I purchased a 36v golf cart battery from Vatrer and it has worked very well too. Overall I am pleased with Vatrer for their quality products, great customer support, warranty, and excellent pricing. Yes, I recommend this company if you want to move away from lead acid to lithium.
This battery was such a great value compared to other brands out there who needs battery Communications when you can save so much money
This battery has delivered everything it's promised so far. Tons of power, reliable, and can't beat the price.
I don't think I even need to say for the price, though it's a big plus. Getting the without the need for a freight truck is super great since I live in the back woods where they dare not tread, UPS and FedEx are more than willing to deliver here.
I got this battery for my solar generator. Works wonderful. The BMS does its job as it should. It will be eventually converted to our main system once we move down to our homestead. Battery works so well I might do a YouTube review on my second one once I can afford it. People need to know about this gem.
Sturdy reliable and easy to manage. The blue tooth helps me keeptrack of their status, SoC and how much amps are getting to each. Very happy purchase and plan on purchasing more
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. Each product undergoes strict safety and performance testing to ensure consistent results in solar energy storage applications.
