- 【Massive 4.6kWh Energy = 8*12V 100Ah AGM Batteries】The Power Queen 51.2V 90Ah LiFePO4 battery supports 100% DOD and 4608Wh of usable energy, while a lead-acid battery only supports about 50% DOD. Approximately eight 12V 100Ah batteries in a 2P4S configuration are required to achieve the same usable energy. Furthermore, you not only get five times the lifespan and at least 20 times the cycle life, but you also save on series and parallel losses and space.
- 【10X cost-effective, saving you a lot of money】The Power Queen 51.2V 90Ah LiFePO4 battery will have 4,000 to 15,000 cycles and a lifespan of up to 10 years. Compared to lead-acid batteries, which only have a lifespan of 2-3 years, our LiFePO4 battery offers significant long-term cost savings. One cycle of the LiFePO4 battery costs approximately... 0,45 €, while the AGM battery is about 4,5 €Each cycle costs money.
- 【1/3 Light & One-touch switch operationPower Queen 51.2V 90Ah rackmount batteries with a standard 4U form factor offer a compact design that saves approximately one-third of the weight compared to lead-acid batteries, thus improving space utilization. One-touch on/off operation makes them easy to use. They are easier to carry and move for RVs, camping, and off-grid applications. These batteries are suitable for power supply while camping and for home systems, with simple installation.
- 【Intelligent BMS & Class A cellWith a built-in BMS capable of powering 4608W loads simultaneously, this battery pack protects the LiFePO4 battery from the most common causes of failure, such as overcharging, over-discharging, overcurrent, and short circuits. We use high-energy-density Class A LiFePO4 cells in our battery pack, and the sheet metal casing makes it both elegant and robust. All batteries are UL and CE certified, providing comprehensive battery protection.
- 【Max. 18.43kWh Capacity Expansion】The 51.2V 90Ah battery allows four to be connected in parallel for a massive 18.43kWh of power (series connection is not recommended). Such a powerful energy expansion system could be widely used for home storage systems, off-grid systems, RVs, trailers, and outdoor activities. (Suitable for energy storage as a start-up; not recommended for golf carts).
