BigBattery 48V 1X HUSKY 2 Lithium Battery Kit

5.12kWh LiFePO₄ Power – Compact High-Performance 48V PWR Solution

Meet the BigBattery 48V 1X HUSKY 2 Kit – the most compact, powerful, and energy-dense 48V LiFePO₄ solution in BigBattery’s lineup. With 5.12kWh of ultra-reliable lithium power, this kit is perfect for golf carts, utility carts, RVs, camper vans, and other 48V mobile power systems.

Powered by Tier 1 lithium iron phosphate (LiFePO₄) cells, the HUSKY 2 delivers exceptional cycle life, fast charging, and high output. This PWR (High Power) variation skips inverter communication protocols, making installation simple while delivering raw, dependable energy.

Designed as a drop-in lead-acid replacement, the kit includes mounting brackets, cables, an external CANBus State of Charge (SOC) meter, and a 48V 110V AC 20A IP65-rated charger. Go further, longer—with less weight and more efficiency.

With an IP65-rated enclosure, advanced Battery Management System (BMS), and self-heating functionality, this battery performs reliably in all weather conditions—from cold mornings to hot afternoons.

Key Features:

  • Battery Capacity: 5.12kWh (48V, 100Ah)
  • Voltage: 48V nominal system
  • Chemistry: Lithium Iron Phosphate (LiFePO₄)
  • Output: High Power PWR version (no inverter communication)
  • Protection Rating: IP65 – Water-resistant, dustproof, vibration-safe
  • BMS: Advanced safety system with self-heating & auto cell balancing
  • Cycle Life: 4,000+ cycles at 80% depth of discharge
  • Installation: Plug-and-play with included components

What’s Included:

  • 1 × 48V HUSKY 2 PWR Battery (FHSKY-48051-G2-PWR)

Understanding Your Power Needs

Power Calculation Guide

Sizing Metric Formula & Example
Energy Consumption (Wh) Formula: Watts × Hours
Example: 60W × 4 hrs = 240 Wh
Battery Capacity (Ah) Formula: Watt-hours ÷ System Voltage (V)
Example: 240 Wh ÷ 12V = 20 Ah
Inverter Size (W) Formula: Total Watts × 1.25 (safety margin)
Example: 300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W) Formula: Sum of all appliance watts used simultaneously
Example: Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery Formula: (Battery Ah × Voltage) ÷ Total Load (W)
Example: (100Ah × 12V) ÷ 240W = 5 hrs
