BP-LFP-2725

LiFePo4 battery pack / 25,6V / 2,5Ah / 64Wh / 10 years UPS accu / UN38.3

Maximum safety and durability!
LiFePO4 high performance battery pack with IEC62133-2 approval for demanding industrial and medical applications

The lithium iron phosphate battery pack BP-LFP-2725 with integrated battery management system (BMS) is designed for applications that place the highest demands on quality, safety and reliability. The intrinsically safe 10 year battery pack with high-energy density is designed for more than 6000 full cycles and is therefore ideally suited for use in particularly demanding applications in the industrial environment and medical technology.

Due to the built-in high-performance LiFePO4 cells in combination with our innovative high current BMS system, the compact BP-LFP-2725 reliably delivers its full performance even at high operating temperatures up to +55°C (up to 15A continuous current) and when frozen at -20°C (up to 6A continuous current). The battery management system perfectly protects the cells from almost all harmful influences and ensures a permanently high capacity. Complex power saving modes prevent the battery pack from discharging quickly when not in use.

Low total cost of ownership compared to lead-acid batteries

In contrast to the supposedly cheaper lead-acid/gel/AGM batteries, high-quality lithium iron phosphate cells have an approx. 15-20x longer service life and cycle stability. In addition, 100% of the full nominal capacity of the LiFePO4 battery pack can be continuously withdrawn. Lead-acid batteries have significant limitations in terms of the depth of discharge and number of cycles, too. When calculating the TCO (Total Cost of Ownership) over the entire period of use of at least 10 years, there is a clear cost advantage compared to lead-acid batteries, especially since the effort for maintenance and battery replacement for LiFePO4 is eliminated during this period.

LiFePO4 – lithium iron phosphate
The particularly safe and long-lasting lithium-ion battery technology

The LiFePO4 battery pack BP-LFP-2725 impresses in safety-relevant applications with a particularly stable battery chemistry, a long service life of at least 10 years and more than 6000 full charge and discharge cycles. For all high-performance battery packs, Bicker Elektronik consciously relies on the particularly safe lithium iron phosphate chemistry, which makes thermal runaway almost impossible. Only brand high-performance cells from LithiumWerks are used for the BP-LFP-2725, which clearly stand out from other manufacturers on the market due to their long service life and high cycle stability. The automated production of the high-performance cells ensures consistently high quality. Combined with the specially developed battery management system (BMS), Bicker Elektronik can guarantee the highest level of product safety and reliability. In combination with our DC UPS UPSI-2412, you can implement powerful DC emergency power supply solutions.

Integrated high-performance battery management system (BMS)

The battery management system (BMS) of the BP-LFP-2725 monitors and controls the entire charging and discharging process of each battery cell in the energy storage system. At the same time, the BMS protects the battery pack from dangers such as short circuit, overcurrent, overtemperature, overcharging and deep discharge. A balancing IC permanently measures and controls the cell voltages as well as the current flow and can react to critical changes within microseconds. The LiFePO4 energy storage system also has electronic overcurrent and short circuit protection so that the battery pack is not damaged in the event of an assembly error. The same applies to overvoltage and undervoltage in the cells. In addition to the MOSFET safety circuit on the battery management system, a special thermal fuse protects the battery pack from the risk of overcharging as a second safety level. A 20A fuse is also installed as a second safety level in the event of a short circuit.

System present function for increased safety

With the system present function, the output of the battery pack remains deactivated (output voltage = 0 V) until it is connected to the DC UPS unit via the communication connector (BAT-DATA) and enabled. Since the components on the BMS board run in standby mode, this power-saving function increases the shelf life of the (charged) battery pack.

Effective 'cell balancing' for long-term high performance

The integrated cell balancing ensures a balanced and uniform charge of all cells, so that the full capacity of the lithium-ion battery pack remains permanently usable. Intelligent balancing algorithms continuously control the LiFePO4 cells. In the event of deviations, the individual cells are adjusted to one another with a balancing current of ~100mA during the charging process. This has a particularly positive effect on the service life, number of cycles and capacity of the energy storage device. You can find detailed information on this topic in our Whitepaper "Choosing the right battery technology for long-lasting and safe DC UPS systems".

FAQ - Questions & Answers

In which applications can the battery pack be used?

The BP-LFP-2725 uses high-performance lithium iron phosphate cells and is safety-tested in accordance with IEC62133-2. It is therefore ideally suited for all industrial and medical applications.

How long is the lifetime of the battery pack?

The BP-LFP-2725 is a particularly high-quality and durable 10 year long-life energy storage device. With the LiFePO4 battery cells, approx. 10 times more charging cycles are possible than with a standard Li-ion battery, as well as approx. 15-20 times more charging cycles than with conventional lead batteries.

How high is the cycle stability of the battery pack?

With the BP-LFP-2725, more than 6000 full cycles (charge and discharge cycles) are possible with normal use.

Does the battery pack have a BMS control?

Thanks to the integrated high-performance battery management system (BMS), the cells are perfectly protected from almost all harmful influences and dangers from the outside (short circuit, overcurrent, overtemperature, overcharging and deep discharge). In addition, the BMS ensures balanced and evenly charged cells within the battery compound and thus ensures a permanently high capacity of the LiFePO4 energy storage device.

In which temperature range can the battery pack be used?

Charge -20…+55°C / Discharge -20…+55°C

Is the battery pack intrinsically safe?

Yes, the BP-LFP-2725 is intrinsically safe. The built-in BMS protects the cells from all harmful external influences. All critical error states are safeguarded redundantly. Even in the unlikely event that the MOSFET main switch is defective, a special thermal fuse protects the battery pack from overcharging the cells. The particularly stable battery chemistry also makes a thermal runaway almost impossible.

How long is the possible bridging time of the battery pack?

~70min@50W load / ~33min@100W load / ~18min@240W load
(Tested and measured in combination with the DC UPS BICKER UPSI-2412)

In which designs is the battery pack available?

The LiFePO4 energy storage systems from Bicker Elektronik are available in two versions: Compact and shrunk for flexible system integration as well as in a robust aluminium chassis for DIN rail mounting.

What transport and safety approvals does the battery pack have?

The BP-LFP-2725 is tested and certified according to
• UN38.3 transport approval
• IEC62133-2 safety approval
