Energy at the highest level

If you are looking for really durable energy sources LiFePO4 battery by Qoltec will be a very good investment. This type of battery is primarily thermal and chemical stability, which enables operation in very extreme conditions, does not negatively affect the battery's performance and allows it to maintain its full capacity.

Modern LiFePO4 technology - more power, less charging

Our batteries are amazing efficient and resistant to deep discharges. They stand out longer service life while maintaining its properties, amounting to over 2000 charge and discharge cycles, and this gives them a big advantage over other batteries currently available on the market. In addition they do not pollute the environment, are recyclable, non-toxic and non-flammable, which increases the safety of use in photovoltaics.

Let your devices work longer

Batteries LiFePO4 it's durability and efficiency in one:
- discharge depth at 100%,
- very low battery self-discharge rate,
- no memory effect, has a positive effect on very efficient cyclic and buffer operation,
- longer service life - above 2000 cycles charging and discharging,
- the battery is completely maintenance-free, no need to replenish electrolyte,
- higher energy density compared to e.g. lead-acid batteries with the same capacity translates into definitely lower weight,
- environmental safety - they do not emit toxic gases and chemicals,
- ability to work in any position, no need to place it in a horizontal position, battery shock resistant.

Application of LiFePO4 batteries

A number of advantages and benefits of functionality of lithium-iron-phosphate batteries makes them meet the expectations of even the most demanding users and are perfect for:
- In photovoltaics, as powering the energy storage, systems off-grid,
- emergency power source, UPS power supplies, voltage converters,
- alarm systems, access control systems,
- campers, trailers,
- electric cars,
- on a yacht, boat, motorboat,
- golf carts, wheelchairs,
- Emergency lighting,
- power tools, lawn mowers,
- electric toys, quads.

BMS, i.e. Intelligent Battery Management System

 All Qoltec LiFePO4 batteries are left equipped with a BMS system, which is an important element protecting the battery. The system takes care of increasing the life of cells. Constantly monitors battery performance protecting cells against overheating, overcharging and deep discharge, cuts off the power supply when values that pose a potential threat to the battery and devices connected to it are exceeded.

How to properly connect LiFePO4 batteries?

Our batteries LiFePO4 can be connected in series and parallel. The only condition that must be met in order not to damage the battery is: using a battery with the same voltage and capacity and degree of wear. If we care about To increase the voltage, we must connect the batteries in series i.e. (+) with (-). Whereas If we want to increase capacity, we connect them in parallel (+) with (+) and (-) with (-). The illustrations below show how to properly connect the batteries.

 We can connect a maximum of 4 batteries together. So, for example, by connecting four batteries with a capacity of 30Ah and a voltage of 12.8V in parallel, we will increase the capacity to 120Ah, and the voltage remains unchanged at 12.8V, in the case of a series connection, the voltages will add up to 51.2V, and the capacity will remain unchanged and will amount to 30Ah.
