Professional--We provide battery solutions and technical support for more than 10 years. Factory-- We have factory, so have competitive price.   Q7:What is LiFePO4 battery 48V? A7:Geerady Systems offers a range of 48V Lithium-Ion battery pack to meet most of our customer needs (up to 192V). PowerBrick®+ battery offer a high level of safety through the use of cylindrical cells in Lithium Iron Phosphate (LiFePO4) technology. Each PowerBrick®+ embeds a BMS (Battery Management System) inside its casing. PowerBrick®+ solutions advantageously replace lead batteries, offering more than doubled capacity for half weight and footprint. Each battery has a 51.2V nominal voltage and can be assembled in series (4S maximum) and parallel (up to 16P) to reach operating voltages from 48V, and up to 192V.. For applications requiring higher voltage or energy, see PowerModule advanced systems. PowerBrick+ battery is enclosed in a sealed ABS case, resistant to moisture and dust (IP 55 or IP 66). PowerBrick+ are lightweight, reliable and environmentally friendly solutions for multiple usages. These batteries can take place for direct Lead-Acid batteries replacement. Even if battery charge can be performed by most Lead-acid chargers, we advise to use a dedicated Lithium-ion charger.

Q8:Which is better LiFePO4 vs lithium ion battery? A8:The LiFePO4 battery has the edge over lithium ion, both in terms of cycle life (it lasts 4-5x longer), and safety. This is a key advantage because lithium ion batteries can overheat and even catch fire, while LiFePO4 does not. Q9:What is the maximum voltage of LiFePO4 battery? A9:In the case of LiFePO4 chemistry, the absolute maximum is 4.2V per cell, though it is recommended that you charge to 3.5-3.6V per cell, there is less than 1% extra capacity between 3.5V and 4.2V. Q10:How long does a 48V lithium ion battery last? A10:about two to three years The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first.       Attention: The lithium battery is the dangerous electric product ,so the shipping freight is higher than the normal product. some country or zone maybe the lithium battery only can be shipped to the ocean prot or airport , so need you consult the seller. Before you paying the order, you should see the technical parameter carefully and confirm the inverter / automatic voltage regulator / stabilizer / solar controller / transformer / uninterrupted power supplier (UPS) can meet your requirement and solve your problem. Besides, tell me the specification and parameters of what you want to buy; the express address to calculate the shipping freight; the input voltage range and rated output voltage. Lithium Battery/Battery pack: if you want to buy, please tell us the below parameters: Where do you need the battery pack used for ? What’s the type of the load ? (AC or DC?) if the load is AC, do you need the inverter? What’s the capacity of the total load? (xxx W /xxx KW) What’s the rated capacity of battery do you need ? (xxx KWH) What’s the output rated voltage of battery do you need ? (12V? 24V? or 48V?) Do you have any requirement for the charge and discharge current ? What’s the current respectively ? Do you have any requirement for the battery dimension and weight ? Where do you decide to use the battery ? Indoors or outdoors ?
