Polinovel stackable long lifespan telecom backup power li-ion 48v lithium ion 50ah lifepo4 battery pack for solar system
The communication facilities of telecom operators tend to be integrated, smaller and lighter. That means more business facilities are to be installed in a limited space. This has prompted higher requirements for the temperature range to be gradually or have been started seeking and studying the new backup battery solution. Based on its technical features as high capacity, high voltage and free of pollution, the lithium-ion battery is widely concerned by people with a rapid development stance. It will be the first choice for the high-requirement backup battery solution.
Polinovel PL48 series lifepo4 lithium battery system is mainly used for the backup battery of the telecom communication industry, especially suitable for application scene of high temperature, limited installation space, restricted load-bearing and long cycle life.
Polinovel 48V 50Ah lithium battery has built-in BMS battery management system, which can manage and monitor cells information including voltage, current and capacity. What’s more, BMS can balance cells charging and discharging to extend cycle life. Multiple batteries can be in parallel for larger capacity and longer power supporting duration requirements.

Product Advantages
● Lithium-ion battery offers extended cycle life and good safety performance.
● Embedded BMS offers voltage, current, temperature protection, and alarm functions. BMS can communicate with other devices.
● Embedded BMS unit measures current, voltage, single-cell surface temperature, and the ambient temperature of the battery.
● Embedded BMS offers four remote functions which can communicate with far-end central control center by computer management.
● The combination of BMS and computer management technology can achieve real-time monitoring and control of various parameters and status.
● The power system has secondary cut-off protection and when the voltage is too low the system will cut off the support from the battery to protect the battery service life.

FAQ
Q1: Does Polinovel support door to door shipping? drop ship ?
A1: Yes. Normally if battery unit weight is below 30kg, we can delivery it to the destination address via Air Express. If battery unit weight is above 30kg, we delivery it via sea shipping. If you want to us to help you to make custom clearance, we would like to do that. We support drop ship.
Q2.: Can we do series and parallel connection by ourselves (12 volt battery)?
A2.: Yes. But, we should pay attention to below tips:
a.: Connect the same spec. battery pack. Please don't mix them.
b.: The voltage difference of the connection batteries should be 50mV below.
c.: Support 4 series OR 4 parallel connection. Please don't do series and parallel connection at the same time.
d. If we don't obey the tips, It may cause battery damaged or shorten the battery lifespan.
Q3.: How can I resell lithium batteries well in my market ?
A3.: Do market research, set your focus application field,learn more knowledge about lithium battery. build your own brand. We can work together with you to explode the market.
Q4.: Why Polinovel guys ask me so many questions? I just want to know the price !!
A4.: Sorry for annoying you. But the discharge current, voltage etc. Information is very important for us to produce the correct battery for you. If we produce the battery which can not achieve the real application discharge current, size etc. That will put both of us in a very embarrassing and lose-lose condition. We also have price list, but it is only for your reference. We should confirm the discharge current etc. Information before we produce your orders.
Q5. Does Polinovel battery include BMS? Can we use it for vehicle?
A5: Yes, our battery pack include BMS, you can use it for low speed vehicles.And make sure the discharge current can meet the application request (please refer to Q4) . If you want to use standard vehicle, please inform us, we need to adopt more complex design BMS and different technology solution.
