LiFe-256Wh - 12.8V 256Wh smart lifepo4 battery in pelicase 1200

Compact, lightweight, and intelligent, the eSMART LiFe-256Wh is a 12.8V / 256Wh smart LiFePO4 battery system built for professional mobile power needs. Housed in the rugged and reliable Peli™ 1200 Case, this battery is designed for plug-and-play use with all Audioroot eSMART-compatible power distributors, delivering real-time State of Charge monitoring and long-lasting performance in a field-ready format.

Smart Power Monitoring

Each eSMART battery integrates an intelligent microcontroller-based BMS that constantly monitors and logs key battery data:

• Battery identification, build date, and serial

• Voltage, temperature, current draw

• Cycle count and overall usage

These metrics are communicated directly to your compatible power distributor, giving you instant, accurate insight into your battery’s status.

Why Choose LiFePO4?

LiFePO4 (Lithium Iron Phosphate) chemistry offers multiple advantages over traditional SLA (lead acid) batteries:

• Lighter and more compact (3.8kg vs. ~18kg SLA equivalents)

• Longer cycle life (up to 1200 cycles at 85% capacity)

• Safer operation and higher current output

• Deep discharge capable

Integrated safety features include:

1. Overcharge protection

2. Over-discharge protection

3. Over-current and short-circuit protection

4. Over-temperature protection

5. Internal cell balancing
