Enerdrive B-TEC Ultra 120Ah Lithium Battery

Enerdrive B-TEC Ultra 120Ah Lithium Battery

The next evolution in battery energy storage! The B-TEC ULTRA 120Ah delivers maximum power with uncompromising safety. Protection from the elements with IP67 rating, ensure ultimate power and peace of mind for all your adventures. Get ready to explore with confidence

The new 12V 120Ah B-TEC ULTRA IP67 Lithium Battery is the next-generation upgrade of our proven 125Ah platform, delivering enhanced charging performance, improved firmware stability, and a more reliable BMS architecture for consistent power in demanding off-grid applications.

Designed with a compact footprint identical to our 100Ah batteries, it enables a seamless, drop-in replacement for systems constrained by existing battery trays or battery boxes, no rework required. This allows users to increase usable capacity and extend runtime without modifying their setup.Compared to traditional 100–120Ah lead-acid batteries, the New 120Ah lithium solution provides up to twice the usable energy, significantly improving runtime while reducing weight and improving overall system efficiency.

BUILT TO WITHSTAND THE ELEMENTS
IP67 Rated. Waterproof. Dustproof. Adventure-Proof. Mount it externally with confidence. The B-TEC ULTRA isn’t afraid to get dirty or wet. With an IP67 rating, it can be fully submerged in water (up to 1 metre for 30 minutes) and is 100% dust-tight. Ideal for external installs on caravans, 4WDs, trailers, and setups where protection from the elements is critical.

HIGH PERFORMANCE POWER
Perfect for power-hungry gear like air compressors, induction cooktops, inverters, fridges, winches, and anything else you throw at it.

• Peak Discharge: 500A (3 seconds)
• Continuous Load: 150A at 25°C
• 6,000 Charge Cycles @ 80% DOD: Built to last with premium Grade-A prismatic cells.
• Series & Parallel Ready: Link up to 4 batteries in series and 4 in parallel to expand your power system.

SAFETY CERTIFIED TO IEC62619
Not all lithium batteries are created equal. The B-TEC ULTRA is IEC62619 certified, meaning it meets one of the highest global safety standards for lithium-ion batteries. That’s important because in remote conditions, failure isn’t an option. B-TEC ULTRA is fully IEC62619 certified at both the cell level and the completed battery pack level. That means every layer of your battery, from internal chemistry to final assembly, is proven safe, robust, and compliant with the strictest international standards.

IEC62619 certification provides:

Rigorous Testing: IEC62619 covers electrical, mechanical, and environmental stress testing. Batteries must pass short circuit, impact, crush, overcharge, and thermal stability tests.

• Global Compliance: It’s a certification recognised worldwide and often required in professional, commercial, and industrial environments.
• Peace of Mind: Many cheap lithium batteries skip this certification entirely, leaving you with unknown risks. B-TEC ULTRA doesn’t cut corners. It delivers verified safety, end to end.

INTEGRATED BATTERY MANAGEMENT SYSTEM (BMS)
The B-TEC ULTRA is equipped with a high-performance BMS that continuously monitors and protects every cell inside the battery. Features include:

• Overcharge & over-discharge protection
• Short-circuit & thermal shutdown
• Temperature-controlled charging
• High/low voltage cutoff

BUILT-IN CELL HEATER
Thanks to a built-in battery cell heater, you don’t have to worry when the mercury drops. The heater is controlled automatically by the BMS to bring the battery up to safe operating temperature, so you can charge in freezing conditions.

WIRELESS MONITORING, TOTAL CONTROL
With the Enerdrive B-TEC App (iOS & Android), you can wirelessly check real-time performance and battery status with just a tap. You’ll know exactly how your battery is performing, anytime, anywhere, including:

• Battery voltage, current, SOC
• Temperature & cycle history
• Individual cell voltages
• System alarms and alerts
• Event tracking & diagnostics
