Lithium iron Phosphate Batteries Smart

Lithium-Iron-Phosphate Batteries Smart


Lithium Battery Smart is a series of Lithium Iron Phosphate (LiFePO4) batteries that offer superior performance, safety, and durability.
They are available in 12.8 V or 25.6 V with various capacities, and can be connected in series, parallel, or series/parallel to create a battery bank
for different system voltages. Some models also feature high current discharge for car jump start applications.

Lithium Battery Smart has the following Features:

1.Rugged: The batteries are designed to withstand harsh conditions and have a long service life.
2.Efficient: The batteries have a high energy density and a low self-discharge rate, which means more power and less waste.
3.Size and weight: The batteries are compact and lightweight, which saves space and reduces transportation costs.
4.Bluetooth and RS485 Communications: The batteries can communicate with external devices via Bluetooth or RS485 ports, allowing you to monitor and control the battery status in real-time.
5.Battery management system (BMS): The batteries have a built-in BMS that protects the cells from overcharging, over-discharging, over-temperature, and short circuit. The BMS also balances the cells to ensure optimal performance and longevity.

A single LFP cell has a nominal voltage of 3.2V. A 12.8 V battery consists of 4 cells connected in series and a 25.6 V battery consists of 8 cells connected in series.

To reduce required balancing time, we recommend to use a little different batteries in series as possible for the application. 24 V systems are best built using 24 V batteries.
And 48 V systems are best built using two 24V batteries in series. While the alternative, four 12 V batteries in series, will work, it will require more periodic balancing time.

I have pleasant experience buying from Shenzhen Suns. They shipped quickly, and very responsive and provided accurate updates. Shipment to Malaysia reaches in just a few weeks with a door to door delivery. Equipment work great, as can be seen from the photos, in the midst of installation and already in operation. The sales representative (Amy) has provided good knowledge and helpful to guide me to make the purchase correctly. Thank you Amy and thank you Shenzhen Suns and this company is highly recommended!
