GWBTEK 51.2V 100AH rack mounted battery designed for seamless integration into standard server racks. It delivers 5.12kWh of reliable power, making it an ideal plug-and-play building block for solar storage, UPS, and off-grid systems.

A deep cycle battery is designed to be regularly discharged down to a low level (e.g., 80-100% of its capacity) and then recharged, unlike a car starter battery which only provides short, high-current bursts. LiFePO4 is an ideal chemistry for deep cycling.

Yes, they are among the safest lithium battery chemistries available. The phosphate cathode material is not prone to thermal runaway (the cause of lithium battery fires), making it very stable even under harsh conditions or if damaged.

The nominal voltage is 12.8V for a 12V battery, 25.6V for a 24V battery, and 51.2V for a 48V battery. This is slightly higher than the 12V, 24V, and 48V of lead-acid systems but is generally compatible with most equipment.

They last significantly longer than lead-acid. In terms of cycle life, they typically last for 2,000 to 4,000 cycles (or more) to 80% of their original capacity. In terms of calendar life, they can last 10+ years, depending on usage and care

Parallel: Yes, connecting batteries in parallel increases capacity (Ah). It is generally recommended to use batteries of the same brand, model, age, and capacity.
Series: Yes, connecting batteries in series increases voltage (e.g., 12V + 12V = 24V). For series connections, it is highly recommended to use a dedicated Battery Management System (BMS) that monitors each cell in the series string, or use batteries designed for series applications.

Yes, but with an important caveat: Discharging: They can be discharged at very low temperatures (as low as -20°C / -4°F) but with reduced capacity.
Charging: You can charge a LiFePO4 battery when its core temperature is below 0°C (32°F), if battery has a internal heating function.

Store it in a cool, dry place. For long-term storage (over 1 month), it's best to charge it to around 50-60% of its capacity. Check the voltage every 6 months and give it a top-up if needed.
