Its serviceable internal design, long cycle life, and flexible system configuration make it an ideal choice for scalable and long-term power systems.

Key Features

  • Marine-Grade Sealed Construction: The sealed plastic case provides excellent resistance to moisture, corrosion, and environmental exposure, making this battery well-suited for marine vessels, docks, and outdoor installations.
  • Built-In Heater for Cold-Weather Charging: Integrated heater pad enables safe charging and reliable operation in low-temperature conditions, ideal for winter boating, cold-climate RV use, and off-grid installations.
  • Bluetooth Monitoring with Smart BMS: Monitor real-time battery performance via Bluetooth using a compatible mobile app. The advanced Smart BMS provides overcharge and over-discharge protection, overcurrent and short-circuit protection, low-temperature charging cutoff, high-temperature charge/discharge cutoff, and automatic cell balancing for optimized performance.
  • Long Cycle Life & 7-Year Warranty: Supports 3,000–8,000 charge cycles and is backed by a 7-year warranty, offering long-term reliability with free maintenance.
  • Flexible System Configuration: Connect in series to create 24V, 36V, or 48V battery banks, or in parallel to increase overall capacity. Important: When connecting batteries in series, all batteries must be at the same State of Charge (SOC) prior to connection to ensure balanced operation.
  • Serviceable, User-Friendly Design: Features a detachable cover with replaceable BMS and cells, extending service life and simplifying maintenance if required.

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
