1. High C-Rate Performance

• 5C Continuous Discharge (100A for 20Ah model) – Delivers instant high current for acceleration and heavy loads.

• 3C Fast Charging – Reduces downtime with rapid recharge capability.

• Low internal resistance (<0.5mΩ) minimizes heat generation.

2. Military-Grade Safety (LiFePO4 Chemistry)

• Zero thermal runaway – Safe under puncture, overcharge, or short circuit.

• Stable 3.2V voltage plateau ensures consistent power delivery.

3. Long Cycle Life & Durability

• ≥4,000 cycles at 80% DoD (Depth of Discharge) – 3x longer than lead-acid batteries.

• Wide temperature range:

• Charge: 0°C to 55°C

• Discharge: -20°C to 60°C

4. Ultra-Lightweight & Compact

• Weight: ~0.5kg (20Ah) / ~0.55kg (22Ah) – 60% lighter than lead-acid equivalents.

• Dimensions: ~130mm (L) × 35mm (W) × 100mm (H) – Fits modular battery packs.

5. Maintenance-Free & Eco-Friendly

• No memory effect, no liquid electrolytes.

• RoHS-compliant – Free of cobalt, nickel, and heavy metals.

1. Electric Mobility

• Golf Carts & Low-Speed EVs: Provides high torque for uphill climbs and long runtime.

• E-Bikes & Scooters: Lightweight alternative to SLA batteries with 5x lifespan.

2. Energy Storage Systems (ESS)

• Solar/Wind Buffer: Handles sudden load surges in off-grid systems.

• Portable Power Stations: Compact size suits high-power DIY builds.

3. Industrial & Robotics

• AGVs (Automated Guided Vehicles): Supports fast acceleration/deceleration cycles.

• Power Tools: Sustains high-current demands for drills, saws, etc.

4. Marine & RV

• Trolling Motors: Delivers burst power for fishing boats.

• Campervan House Batteries: Lightweight + deep-cycle capability.
