Description

LiFePO4 batteries are the safest lithium-ion batteries on the market. The nominal voltage of a LiFePO4 cell is 3.2V, unlike 2V for lead-acid batteries, so a 12.8V battery contains 4 cells connected in series, and a 25.6V battery contains 8 cells connected in series.

WARRANTY: 3 YEARS

Our LiFePO4 batteries do not require full charging. The lifespan of such a battery is improved with partial charging compared to full charging, which is a significant advantage over acid batteries.

Other advantages include wide temperature operating ranges, excellent cycle performance, low internal resistance, and high efficiency, reaching up to 92%.

Cell voltages, temperature, and error conditions can be monitored via Bluetooth, which is very useful for identifying potential issues such as cell imbalances.

Our LFP batteries feature integrated cell balancing and monitoring. Up to five batteries can be connected in parallel, and up to four 12V batteries or two 24V batteries can be connected in series to assemble a 48V battery bank with up to 1500 Ah. Cell balancing/monitoring cables can be daisy-chained and must be connected to a battery management system (BMS).
