VOLT POLSKA LiFePO4 Battery 25.6V 150Ah 150A - 3.84kWh Deep Cycle Lithium Iron Phosphate

With a cycle life exceeding 6000 cycles at 80% depth of discharge, the VOLT POLSKA 25.6V 150Ah LiFePO4 battery delivers up to 10 times the lifespan of traditional lead-acid batteries. Its 3.84 kWh energy capacity and 150A continuous discharge make it a powerhouse for solar, marine, EV, and backup applications.

Overview

The VOLT POLSKA LiFePO4 battery replaces bulky and heavy lead-acid units with a lightweight, high-efficiency solution. Its nominal voltage of 25.6V aligns perfectly with 24V systems, and the 150Ah capacity ensures long runtime. The battery supports a maximum continuous charging current of 150A, allowing for rapid recharging, while the built-in BMS safeguards against overcharge, over-discharge, overcurrent, short-circuit, and temperature extremes. Cell balancing ensures each of the 8 series-connected cells remains at optimal charge.

What stands out

• Impressive cycle life: more than 6000 cycles at 80% DoD – up to 10 times longer than lead-acid.
• High discharge capability: 150A continuous, with 450A peak for 3 seconds to handle high surge loads.
• Integrated BMS with comprehensive protection and cell balancing.
• Wide operating temperature range: -20°C to 60°C discharge, 0°C to 45°C charge.
• Can be paralleled up to 4 units to achieve 600Ah capacity (or more depending on configuration).
• Low self-discharge rate of less than 3% per month.
