- Notes before purchasing:
These new batteries were purchased by customers who accidentally purchased the wrong capacity or incompatible batteries for their applications. We assure you that our batteries are thoroughly inspected and tested before delivery (only a few have minor surface scratches). We offer a 4-year warranty on our new batteries, and a 4-year warranty on our used, very good batteries. 3-year warranty.
- 【Massive 4.6kWh energy = 8*12V 100Ah AGM batteries】Power Queen's 51.2V 90Ah LiFePO4 battery supports 100% DOD and 4608Wh of usable energy, while lead-acid batteries only support about 50% DOD. It requires approximately 8 x 12V 100Ah batteries in a 2P4S configuration to achieve the same usable energy. In addition, you not only get 5 times the cycle life and at least 20 times the cycle life, but also save series and parallel losses and space.
- 【10X cost-effective save your money to a great extent】Power Queen's 51.2V 90Ah LiFePO4 battery can be charged 4,000 to 15,000 times, achieving 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. A LiFePO4 battery costs about €0.45 per cycle, while an AGM battery costs about €4.50 per cycle.
- 【1/3 Easy & One-touch Switch Operation】Power Queen 51.2V 90Ah rackmount batteries feature a standard 4U size. The compact design saves a reasonable 1/3 of the weight compared to lead-acid batteries and improves space utilization. The one-touch ON/OFF button makes operation easy. It's easier to carry or move for RV, camping, and off-grid applications. The battery is suitable for camping power and home systems with easy installation.
- 【Intelligent BMS & Class A cell】With a built-in BMS that can drive 4608W of loads simultaneously, it can protect the LiFePO4 battery from common causes of battery failure, such as overcharging, overdischarging, overcurrent, and short circuit. We use Class A LiFePO4 cells with higher energy density in our battery pack, and the metal casing makes the battery exquisite and robust. All batteries are UL and CE certified, providing comprehensive battery protection.
- 【Max. 18.43kWh capacity expansionThe 51.2V 90Ah battery allows four batteries to be connected in parallel for a whopping 18.43kWh of power (not acceptable in series). This powerful energy expansion system is widely used for home storage systems, off-grid systems, RVs, trailers, and outdoor activities. (Suitable for energy storage rather than startup; not recommended for golf carts.)
- A notice: This battery is NOT suitable for use as a starter battery or golf cart battery. For further information please contact our service team: service.de@ipowerqueen.com
