SOK 48V 100Ah Server Rack Battery Features
This Battery Lasts Over 6,000 Cycles Without Losing Its Edge
At 80% depth of discharge, you get more than 6,000 charge cycles that's over 20 years of daily use. Most lead-acid batteries quit after 500 cycles. This one just keeps going, saving you thousands in replacement costs over time.
A Built-In Heater Keeps It Running Even in Freezing Weather
Cold kills most lithium batteries. The SK48V100N has a built-in 100-watt heating pad that warms the cells before charging starts. Whether you're off-grid in winter or parked in the mountains, this battery won't let the cold stop it.
The Smart BMS Protects Your Battery Around the Clock Automatically
Five temperature sensors and a multi-protection Battery Management System watch over your battery 24/7. It guards against overcharging, over-discharging, and short circuits — all without you doing a single thing. Just plug in and forget about it.
It Connects to Almost Any Inverter Right Out of the Box
With RS485 and CANBus communication built in, this battery talks directly to most popular inverters including Sol-Ark and Victron. Your inverter adjusts charging automatically based on real battery data, making your whole system run smarter and safer.
The Compact 3U Design Fits Any Standard Server Rack Perfectly
This is the smallest 3U rack battery on the market. It slides into any standard 19-inch server rack and installs in minutes. You can stack multiple units as your power needs grow no rewiring, no hassle, just more storage.
Bluetooth Updates Let You Upgrade the Battery From Your Phone
Most batteries are frozen the moment they ship. Not this one. Over-the-air Bluetooth updates keep the firmware current. You can even switch inverter protocols straight from your phone no laptop, no cables, no service technician needed.
A Pre-Charge Circuit Shields the Electronics From Startup Damage
When power systems turn on, a sudden rush of electricity can damage sensitive components. The built-in 100,000µF pre-charge circuit absorbs that surge before it reaches the BMS. It's a small detail that quietly adds years to your battery's life.
SOK 48V 100Ah Server Rack Battery Warranty
SOK provides a 10-year limited warranty policy, ensuring the absence of defects in materials, workmanship, and performance during the warranty period.
