Electrical Safety

Comprehensive Protection

The Telecom LFP 100 and LFP 150 are engineered for maximum safety with embedded protection mechanisms.

  • • UL Certified: Meets rigorous safety standards.
  • • Embedded Breaker: 125A (LFP 100) / 150A (LFP 150) DC breaker for overcurrent protection.
  • • BMS Switch: AI-managed Battery Management System switch for automated safety control.

Thermal Safety

No Thermal Runaway Risk

LiFePO₄ chemistry produces no oxygen at 300°C, eliminating thermal runaway risk.

Thermal Stability Comparison
$$\text{LiFePO}_4: \Delta H_{\text{decomp}} \ll \text{LiCoO}_2, \text{NMC}, \text{NCA}$$

Cycle Management

Depth of Discharge (DoD) Optimization

To achieve the 6000 cycle life, our BMS optimizes the Depth of Discharge (DoD). Operating at 80% DoD significantly extends the service life compared to full discharges.

Lifetime Energy Calculation
$$E_{total} = C_{nom} \cdot N_{cycles} \cdot \text{DoD} \cdot \eta_{roundtrip}$$

Our BMS maintains a precise State of Charge (SoC) estimation to ensure optimal DoD execution.

Electrochemistry

Lithium Iron Phosphate (LFP) cell reactions

Cathode (Positive)
$$\text{FePO}_4 + \text{Li}^+ + e^- \xrightarrow{\text{discharge}} \text{LiFePO}_4$$
Anode (Negative)

Overall Cell Reaction
$$\text{LiFePO}_4 + \text{C}_6 \rightleftharpoons \text{FePO}_4 + \text{LiC}_6 \quad E^0 = 3.2\text{V}$$

Evolution

Battery Roadmap

Telecom LFP 100

Shipping since 2025
Engineering Changes
  • 51.2 V lithium iron phosphate pack, 16-cell series string
  • 3U, 19-inch rack-mount
  • BMS with RS485 Modbus and SNMP, integration-tested with common site controllers
  • UN 38.3 tested, Class 9 shipping certification
  • Lug-free, plug-and-play power connectors
Capacity, Runtime & Site Impact
  • Reference unit: 100 Ah / 5.2 kWh in 3U, 1.7 kWh per rack unit

What it means: The baseline every delta in this roadmap is measured against.

Telecom Sodium 160

Launched 2026
Engineering Changes
  • Sodium-ion cells, lithium-free chemistry
  • 48 V class, 16-cell series string
  • 5.2U, 19-inch rack-mount
  • Integrated cell-heating option for sub-zero charging
  • BMS with RS485 Modbus and CAN, SNMP option
Capacity, Runtime & Site Impact
  • Capacity +60% (160 Ah, about 7.7 kWh)
  • Discharge rated to −40 °C
  • Cycle life 8,000+
  • Ships and stores at 0 V (sodium-ion transport class)
  • Energy per rack unit 1.5 kWh/RU (−14%)

What it means: +60% backup runtime at the same load in 2.2 extra rack units; unheated-enclosure discharge at −40 °C; safer logistics with fully discharged transport

Telecom LFP 150

Now available
Engineering Changes
  • 150 Ah-class prismatic lithium iron phosphate cells, 16-cell series string
  • 4U, 19-inch rack-mount, same width as LFP 100 with a deeper chassis
  • Barrier terminal blocks for ring-lug power cables, with clear flip covers
  • Power path rated for the 150 Ah pack (bus bars, breaker, MOSFET stage)
  • BMS protocol stack carried over from LFP 100
  • UL 1973, UL 9540 and UL 9540A
Capacity, Runtime & Site Impact
  • Capacity +50% (150 Ah, 7.8 kWh)
  • Energy per rack unit +12.5% (1.95 vs 1.73 kWh/RU)
  • +1U height, deeper chassis

What it means: +50% backup runtime at the same load, or the same runtime from fewer strings; 12.5% more stored energy per cabinet rack unit

LFP 100 to LFP 150: capacity +50%, energy per rack unit +12.5%. Sodium 160 trades rack space for −40 °C discharge, 8,000+ cycles and 0 V transport.

Capacity and energy figures are nominal. Runtime deltas assume equal load and depth of discharge.
