Advanced lithium battery built for high performance and long life

The B-TEC ULTRA Series battery delivers exceptional power efficiency, safety, and reliability for off-grid, RV, and marine applications. Designed with advanced BMS control and intelligent monitoring, it ensures optimal charging, stable output, and maximum cycle life under demanding conditions.

Key Features

• High-capacity LiFePO₄ chemistry: Provides superior energy density, long cycle life, and enhanced safety over traditional lead-acid batteries.
• Smart BMS protection system: Monitors cell voltage, temperature, and current in real time to prevent overcharge, over-discharge, and short circuit.
• Integrated SOC display panel: Includes LED indicators showing battery state of charge (0–100%) and system operation status for easy monitoring.
• ON/OFF system button: Enables power isolation during long storage periods to reduce self-discharge.
• Advanced heat dissipation design: Features an aluminium heat sink for internal temperature balance and consistent performance.
• Rugged IP67-rated housing: Sealed enclosure resists water and dust ingress, ideal for harsh outdoor or marine conditions.
• Pressure relief valve: Automatically equalises internal case pressure while maintaining waterproof integrity.
• Communication ports (M12-6P): Allows parallel communication between batteries or connection to external monitoring systems.
• Flexible installation options: Supports up to four batteries in series (12.8 V – 51.2 V configurations) or parallel operation for higher capacity.
• LED run and alarm indicators: Green light signals normal operation; red indicates system fault for quick diagnostics.
• Parallel balance protection: Requires equal-length parallel cables to ensure current balance between connected batteries.
• Integrated carrying handles: Enable safe and easy transport or removal from battery trays.

Engineered for performance and endurance, the B-TEC ULTRA delivers dependable energy storage for off-grid, mobile, and marine power systems.
