Enerdrive B-TEC ULTRA Lithium Battery 12V 300Ah
Enerdrive B-TEC ULTRA 12V 300Ah Lithium Battery Gen 3
Massive Power for Massive Adventures
When "enough" isn't quite enough, the Enerdrive B-TEC ULTRA 12V 300Ah Lithium Battery delivers the ultimate high-capacity energy solution. Designed for large-scale off-grid systems, long-range touring, and marine applications, this 300Ah powerhouse offers the equivalent usable energy of multiple heavy lead-acid batteries in a single, streamlined, and waterproof package.
The B-TEC ULTRA 300Ah is the flagship of the Enerdrive lithium range. It is engineered specifically for users who demand extended run times for high-draw appliances—like air conditioners, induction cooktops, and large refrigeration systems—without the weight penalty of traditional battery banks.
Encased in a ruggedised, IP67-rated waterproof housing, this battery is built to survive the vibration of corrugated roads and the moisture of marine environments. At its core is a sophisticated internal Battery Management System (BMS) that provides total protection and peace of mind. With integrated Bluetooth monitoring, you have complete visibility of your power levels at your fingertips, making energy management easier than ever.
Features:
Mounting Ready: Supplied with a dedicated tray and straps for secure installation
300Ah Massive Capacity: A single unit provides enough energy to power large 12V systems for days on end.
IP67 Waterproof & Dustproof: Fully sealed construction allows for installation in areas exposed to the elements, such as external canopies or boat compartments.
High Discharge Capability: Optimised to handle high-current inverter loads for domestic-style appliances.
Integrated Bluetooth Monitoring: Use the Enerdrive B-TEC app to monitor voltage, current, state of charge (SOC), and temperature in real-time.
Advanced Internal BMS: Protects against overcharge, over-discharge, short circuit, and high/low temperatures.
Weight Efficiency: Significantly lighter than a 300Ah AGM setup, saving precious payload for your vehicle or boat.
Long Cycle Life: LiFePO4 chemistry provides thousands of cycles, ensuring years of reliable service in demanding conditions.
Built-in Heater: Included for reliable performance in cold climates.
Safety & Monitoring: Integrated SOC Indicator, Relief Valve, and On/Off Switch.
Installation: Comes with a mounting tray and straps.
