LiFePO4 Battery

What is a LiFePO4 battery?

LiFePO4 is a lithium-iron-phosphate battery that offers significant advantages over batteries in other technologies.

Thanks to the long service life of over 2000 cycles, they provide us with over 10 years of use, and high current efficiency and over 3 times less weight than the equivalent in acid technology -leaded, ideally suited as a power source in motorhomes, boats, electric vehicles or solar installations.

Intelligent long-term solution

Despite the higher price, LiFePO4 batteries are characterized by a much lower operating cost, which means that the purchase pays for itself very quickly. Over its lifetime, the LiFePO4 battery costs over 100% less than a standard AGM battery, making it a worthwhile investment and a smart long-term solution.

The table shows a comparison of the total cost of ownership for 12V 100Ah batteries.

The highest class of energy

LiFePO4 batteries offer higher energy density than lead-acid batteries on the market. There is no memory effect that reduces the real capacity of the battery along with its use, and the self-discharge is small, so charging the battery does not cause problems. The batteries also have a constant discharge voltage, which makes them the safest batteries on the market.

When buying a lithium-iron-phosphate battery, we do not have to worry about maintenance, it is not required. All batteries lose energy naturally when idle. With LiFePO4 this loss is kept to a minimum, thus ensuring you have access to energy every time you need it.

Countless uses

LiFePO4 batteries have been designed for easy access to an efficient energy source that can cope with even the toughest conditions. The nanophosphate technology ensures thermal and chemical stability, so that the temperature does not significantly affect their performance. They can work effectively in a wide temperature range from -10°C to 55°C while maintaining their high capacity.

They are used, among others, as batteries for electric cars, where, thanks to the high discharge rate, they perfectly cope with starting cars and ensure stable and long-lasting driving. They are also used where the size and weight of the energy source is important - in motorhomes, electric boats or wheelchairs. They are also used in photovoltaics, which is slowly becoming the energy standard for households and even for entire estates.

Your and your battery's safety

The batteries are equipped with a high-class BMS (Battery Management System). The task of this system is to monitor the voltage and temperature of the cells during both charging and discharging. If dangerous values are exceeded, the system cuts off the power supply, thus ensuring the safety of the battery, connected devices and, most of all, the user!

LiFePO4 batteries are much safer than lithium-ion (li-on) solutions, while at the same time characterized by significantly higher thermal stability, resistance to changing weather conditions or high current charging, which makes them an excellent proposition for all customers expecting many years of maintenance-free operation.

/ Much more durable and safer than lithium-ion cells

/ Unlike their lead-acid counterparts, they do not emit hazardous gases, and there is no risk of exposure to corrosive electrolytes

      Frequently Asked Questions
      How long does the ebike battery last?
      View
      A standard Green Cell battery can last for around 500 full cycles - meaning a full discharge and recharge. If we calculate one cycle per week and the natural wear and tear of the cells over time, the battery life can last up to 10 years with careful driving. How long does the ebike battery last?

      Battery for boat or yacht - how to choose the right one?
      View
      LiFePO4 batteries are devices that can handle yacht, boats or photovoltaic requirements. What we should know before buying the battery: -LiFePO4 battery have voltage of 12.V; -it cannot be connected in serial or parallel configuration, because of the BMS (Battery Management System) onboard; -to achieve the longest lifespan of the battery it should work within range of it's designated temperture.
      What is the difference between AGM and LiFePO4 battery?
      View
      The main difference between AGM and LiFePO4 batteries:
      AGM - a group of gel batteries having AGM (Absorbent Glass Mat) that is called VRLA (Valve Regulated Lead). In comparison to traditional batteries, AGMs have up to 4 times the lifespan and higher number of cycles. All thanks to previously mentioned fiber glass.
      LiFePO4 - a group of lithium-iron-phosphate batteries. Their construction is based on four cells connected in serial. Every one of them works with voltage of 3.2V which gives 12.8V in summary. One of the most imporant parts of this battery is it's BMS - Battery Management System.
      Can the battery capacity (mAh) be higher?
      View
      Choosing battery with higher capacity shouldn't be of any issue. The capacity of the battery is expressed in amp-hours (Ah). The higher the capacity (e.g. 80Ah), the longer the time that battery can stay on during one cycle, which in turn let's us be more mobile and independent.
