Get efficiency at the highest levelIf you are looking for a safe and long-lasting energy source, the LiFePO4 battery from Qoltec will be a very good investment. This type of battery is all about thermal and chemical stability, allowing you to work in very extreme conditions without compromising the performance of the battery and allowing it to retain its full capacity.Advanced LiFePO4 technology - more power, less chargingOur batteries are extremely efficient and resistant to deep discharges. They are characterised by a longer service life while maintaining their properties of more than 2000 charge and discharge cycles, and this gives them a major advantage over other batteries currently available on the market. In addition, they are non-polluting, recyclable, non-toxic and non-flammableEnsure a reliable source of energy LiFePO4 batteries are durability and performance in one :- 100% depth of discharge,- very low self-discharge rate,- no memory effect, very efficient cycling and buffer operation,- longer service life - more than 2000 charge and discharge cycles,- 100% non-combustible battery - no risk of overheating, arson or explosion,- 100% maintenance-free, no need to top up the electrolyte,- lower weight and at the same time higher energy density compared to e.g. lead acid batteries,- environmentally safe - no toxic gases or chemicals are released,- can be operated in any position, no need to set it horizontally,- shock-resistant.Application of LiFePO4 batteriesThe wide range of advantages and functional benefits of lithium-iron-phosphate batteries means that they will meet the expectations of even the most demanding users and are perfect for :- in photovoltaics, as power storage, off-grid systems,- uninterruptible power supplies, UPS, voltage converters,- alarm systems, access control systems,- campers, trailers,- electric cars,- yachts, boats, motorboats,- golf carts, wheelchairs,- emergency lighting,- power tools, lawnmowers,- electric toys, quads.BMS or intelligent battery management systemAll Qoltec LiFePO4 batteries are equipped with a BMS, which is an essential element of battery protection. It constantly monitors the operation of the battery, protecting the cells from overheating, overcharging and deep discharge, cutting off the power supply when values are exceeded that pose a potential danger to the battery and connected devices.How to connect Lifepo4 batteries correctly ? Our LiFePO4 batteries can be connected in series and parallel. The only condition to be fulfilled in order not to damage the battery is to use a battery with the same voltage, capacity and degree of wear. If you want to increase the voltage, you must connect the battery in series, i.e. (+) with (-). If we want to increase capacity, we connect in parallel (+) with (+) and (-) with (-). A maximum of 4 batteries can be connected together. So, for example, connecting in parallel four batteries with a capacity of 150Ah and a voltage of 12.8V will increase the capacity to 600Ah and the voltage will remain the same at 12.8V, in the case of a series connection, the voltages will add up to 51.2V and the capacity will remain the same at 150Ah. The following illustrations show how to correctly connect the batteries together.Confidence confirmed by a guaranteeDo you care about the high quality of the product you are buying?
