Thermal and chemical stability

If you’re looking for a truly durable energy source, a Qoltec LiFePO4 battery will be a very good investment. This type of battery is characterised above all by thermal and chemical stability, which enables it to operate in extremely harsh conditions without adversely affecting its performance and allowing it to retain its full capacity.

3000 cycles of reliable power – choose longevity with LiFePO4

3000 charge and discharge cycles
>

LiFePO4 batteries combine durability and performance:

– a depth of discharge of 100%,

– a very low self-discharge rate,

– no memory effect, which is beneficial for highly efficient cyclic and buffering operation,

– longer service life – over 3000 cycles of charging and discharging,

– higher energy density compared to, for example, lead-acid batteries of the same capacity, resulting in significantly lower weight,

– completely maintenance-free battery, no need to top up the electrolyte,

– lower weight and, at the same time, higher energy density compared to, for example, lead-acid batteries,

– environmentally safe – they do not emit toxic gases or chemical compounds,

– capable of operating in any position, no need to be positioned horizontally, the battery is shock-resistant.

Advanced LiFePO4 technology – more power, less charging

High-performance and resistant to deep discharge

Our batteries are extremely high-performance and resistant to deep discharge. They are characterised by a longer service life whilst maintaining their properties, amounting to over 2000 charge and discharge cycles, which gives them a significant advantage over other batteries currently available on the market.
Furthermore, they do not pollute the environment, are recyclable, non-toxic and non-flammable, which enhances safety in photovoltaic applications.

BMS, or Intelligent Battery Management System

All Qoltec LiFePO4 batteries are fitted with a BMS, which is a key component in protecting the battery. The system ensures an extended service life for the cells. It constantly monitors the battery’s operation to protect the cells from overheating, overcharging and deep discharge, and cuts off the power supply should any values be exceeded that could pose a potential risk to the battery and the devices connected to it.
