Resistance to overheating. LiFePO₄ does not ignite at temperatures up to 270°C, and even in cases of short circuit or overcharging, heating occurs gradually without a sudden temperature spike.
Chemical stability. The iron‑phosphate structure is chemically inert and does not release oxygen even when overheated (up to 270–300°C).
Built‑in safety measures. High‑quality LiFePO₄ batteries include a BMS (Battery Management System) that prevents overcharging, overheating, and short circuits, while also monitoring battery parameters and using this data to improve safety and extend battery life.
Charging Speed
LiFePO₄ batteries can be charged faster than other types of batteries. For example, when using an AC power supply, charging may take 1–3 hours. The actual charging time depends on the battery capacity, current, and charging method.
The recommended charging current is 0.5C (a current equal to 50% of the nominal capacity).
Environmental Friendliness
They do not contain toxic heavy metals (cadmium, lead). This reduces the risk of heavy‑metal pollution during production, use, or disposal.
Suitable for recycling – the batteries are used to recover valuable base materials such as lithium, iron, and phosphorus, which can be reused in manufacturing.
Proper disposal: Batteries are collected in designated containers and then sent for recycling; battery waste must not be disposed of in landfills.
We provide battery recycling at the end of their service life.
Durability
PolyBat LFP batteries come with a 3‑year or 6000‑hour operating warranty (with the option to extend to 6 years or 10,000 operating hours).
They can withstand up to 20,000 operating hours at a discharge range of 10% to 90%, as configured in the BMS system.
Even with daily use (one cycle per day), the average service life of LFP batteries is around 15 years.
Slow capacity degradation. The iron‑phosphate cathode remains structurally stable even after thousands of cycles, without losing its ion‑exchange capacity.
High current tolerance. LiFePO₄ can safely operate at charging currents up to 0.5C and discharging currents up to 3C for short periods.
Factors Determining Battery Life
Depth of Discharge (DoD) — the deeper each discharge cycle is, the faster the battery life decreases. Ideally, the charge should not fall below 20%.
Temperature conditions: Operating at temperatures above 45°C or below –20°C reduces efficiency and accelerates wear. The optimal range is –5°C to +25°C.
Deep discharges — discharging the battery below 10–20% of its capacity may lead to progressive capacity loss and severe damage.
It is recommended to use the chargers provided by Polybet‑Export Ltd, as they are programmed specifically for the PolyBat batteries offered.
Avoid constant charging to full capacity(100%) — it is better to maintain the charge level within the 20% to 80% range.
