Features
Details from the Wattcycle Amazon listing:
- 🍃【3U Server Rack Battery】This 48V 100Ah LiFePO₄ battery delivers 5.12kWh (5120Wh) usable energy with up to 5120W output, designed in a standard 3U 19-inch server rack format. Measuring 19.09 × 17.72 × 5.24 in and weighing 91.9 lbs, it is significantly lighter than traditional lead-acid batteries, making installation easier for RVs, camper vans, small cabins, off-grid systems, and rack-mounted energy storage while maximizing vertical space efficiency.
- 🍃【EV-Grade A+ Cells & Long Cycle Life】Built with premium 102Ah EV-grade A+ LiFePO₄ cells, this battery supports 15,000+ charge-discharge cycles at 60% DOD. It provides stable voltage output for solar storage, RV power systems, UPS backup, and industrial applications, offering a much longer lifespan and lower total cost of ownership compared to conventional lead-acid battery banks.
- 🍃【100A Smart BMS & All-Weather Protection】Equipped with a high-performance 100A BMS, this battery safeguards against overcharge, over-discharge, over-current, short-circuit, and temperature extremes. It operates reliably from –4°F to 149°F, while the full-metal enclosure offers added protection against vibration and impact. The inherently stable LiFePO₄ chemistry further minimizes risks of leakage and thermal runaway for dependable long-term use.
- 🍃【LCD, Bluetooth & CAN Communication】The integrated LCD touchscreen allows quick on-device status checks, while Bluetooth 5.0 enables real-time monitoring of voltage, current, and capacity via a mobile app. With support for CAN, RS485, and RS232 communication protocols, this battery ensures stable data transmission and seamless integration into professional energy storage, UPS, and inverter-based systems.
- 🍃 【Inverter Compatibility & Scalable Energy Storage】 Designed for smooth plug-and-play pairing with leading inverter brands such as Victron and Schneider through CAN and RS485 ports. Start with a single 5.12kWh unit for weekend trips, then expand up to 16 batteries in parallel for a total capacity of 81.9kWh—ideal for full-time RV living, extended off-grid power, home energy storage, industrial applications, and UPS backup systems.
