Freedom Won eTower 2 5.12kWh LiFePO4 Lithium Battery

<h3>Product Overview</h3><p>The Freedom Won eTower 2 is a modular 5.12 kWh lithium iron phosphate (LiFePO4) battery designed for residential backup power, hybrid and solar energy storage systems. Its 51.2 V nominal battery platform provides expandable storage for suitably configured 48 V inverter systems, with integrated monitoring and battery management.</p><h3>Key Features</h3><ul>
<li>5.12 kWh nominal capacity and approximately 4.5 kWh usable energy at 90% depth of discharge.</li>
<li>Expandable from one to six parallel modules, delivering up to 30.72 kWh nominal capacity.</li>
<li>Integrated battery management system (BMS) provides voltage, current and temperature protection.</li>
<li>Wi-Fi and Bluetooth connectivity supports monitoring through the Freedom Won app.</li>
<li>Forced-air cooling and a painted steel enclosure for indoor installations.</li>
<li>CAN bus, RS485 and RS232 communication interfaces.</li>
<li>Manufacturer states backwards compatibility with previous-generation eTower systems, subject to installation requirements.</li>
</ul><h3>Applications</h3><ul>
<li>Residential solar power systems and hybrid energy storage.</li>
<li>Backup power for essential household loads during electricity interruptions.</li>
<li>Modular energy storage installations requiring future expansion.</li>
<li>Time-of-use energy storage applications with a compatible inverter and system design.</li>
</ul><h3>Why Choose This Product?</h3><p>The eTower 2 combines a modular battery format with local manufacturer support, built-in monitoring and expansion options. It is a practical option for customers who want to start with a single battery and increase storage capacity as their requirements change.</p><h3>Important Notes</h3><ul>
<li>This listing is for one 5.12 kWh eTower 2 battery module, not a complete multi-module tower.</li>
<li>Pedestal, stacking kits, rack or wall-mount hardware and DC cable kits are optional accessories; confirm requirements and inclusions before ordering.</li>
<li>Do not connect battery modules in series. Consult the manufacturer's technical documentation for parallel configuration requirements.</li>
<li>Inverter compatibility, communications configuration and installation design must be checked by a qualified installer.</li>
<li>Designed for indoor use. Manufacturer's recommended ambient operating temperature range is 10–25 °C.</li>
<li>Warranty: 5 years or 4,000 cycles at 90% depth of discharge, subject to manufacturer terms.</li>
<li>IEC 62619 certification is listed by the manufacturer as in progress; do not treat it as completed certification.</li>
