What Is The 72V FALCON LiFePO4 28Ah 2.1kWh Battery?
The 72V FALCON LiFePO4 28Ah 2.1kWh battery is a high-voltage lithium iron phosphate (LiFePO4) energy storage system designed for applications demanding compact size, safety, and efficient power delivery. With a nominal voltage of 72V and 28Ah capacity, it provides 2.1kWh of energy—ideal for lightweight electric vehicles, portable solar storage, and UPS systems. Built with rugged LiFePO4 cells, it offers >6,000 cycles at 80% depth of discharge (DoD) and operates in temperatures from -20°C to 60°C. Integrated BMS safeguards prevent overcharge, overheating, and short circuits, while modular designs allow scalability for commercial or industrial use.
How does the 28Ah capacity impact performance?
A 28Ah capacity balances energy density and portability, delivering 2.1kWh for mid-range mobility needs. Pro Tip: Pair it with 72V controllers rated ≥80A to avoid MOSFET burnout during peak loads.
While lower in capacity than industrial 120Ah units, the 28Ah variant excels in weight-sensitive applications. For instance, a 28Ah pack weighs ~25kg—35% lighter than equivalent lead-acid systems—making it ideal for e-scooters needing ≤60km range. The 170Wh/kg energy density ensures compact sizing, fitting into tight EV compartments. However, runtime trades off against higher-capacity models: a 72V 200Ah battery provides 14.4kWh but doubles the weight. Transitioning to thermal management, LiFePO4’s inherent stability reduces cooling demands compared to NMC cells.
| Metric | 28Ah LiFePO4 | 120Ah LiFePO4 |
|---|---|---|
| Energy (kWh) | 2.1 | 8.6 |
| Weight | ~25kg | ~100kg |
| Cycle Life | >6,000 | >4,500 |
What safety features differentiate this battery?
The FALCON series prioritizes multi-layered BMS protection, including cell balancing and thermal cutoffs. Unlike basic packs, its firmware monitors individual cell voltages ±10mV.
Built-in safeguards address critical failure modes: for example, the BMS disconnects at ≤55°C cell temperatures to prevent thermal runaway—crucial for high-drain EV accelerations. Mechanically, prismatic LiFePO4 cells resist punctures better than cylindrical alternatives, while flame-retardant casing contains rare thermal events. Pro Tip: Always store these batteries at 30-50% charge if inactive >3 months to minimize calendar aging. Transitioning to certifications, while not explicitly stated, similar 72V LiFePO4 packs typically meet UN38.3 and IEC62133 standards for transport and operational safety.

FAQs
Yes, but ensure your charge controller supports LiFePO4 voltage profiles (3.45-3.65V/cell). MPPT units with lithium presets prevent undercharging.
What’s the peak discharge current?
At 2C continuous (56A), it briefly handles 3C (84A)—sufficient for most 72V 5-7kW motors. Sustained high loads accelerate capacity fade.
