Enerdrive Lithium Battery EPL-300BT-12V-G2: Monitor & Manage With Ease

This battery’s integrated Bluetooth Smart Monitoring System gives you instant access to live data via the Enerdrive app on Android™ or Apple® devices. View key metrics in real-time:

• Battery Capacity, Voltage & Amps
• State of Charge (SOC) & State of Health (SOH)
• Individual Cell Voltage
• Battery Temperature & Cycles
• Battery Alarms & Event Logs

Its advanced internal BMS optimises each prismatic cell and provides protection from overcharge, over-discharge, overheating, and short circuits. If your battery is ever fully discharged, simply press the built-in reset button—no external voltage or equipment required.

Enerdrive B-TEC Battery EPL-300BT-12V-G2 vs AGM: Smarter, Lighter, More Usable Power

This lithium battery is not only smarter—it’s more efficient and compact than traditional AGM batteries:

• 300Ah Lithium = 480Ah AGM Equivalent
• 60% more usable energy
• Roughly 50% lighter and 30% smaller
• Includes metal tray and hold-down strap for easy mounting

It's ideal for camper trailers, 4WD setups, caravans, marine power, and remote energy systems.

Installation Notes & System Expansion

This battery is designed for internal use only and must not be installed in engine bays, wet environments, or compartments that carry gas. The EPL-300BT-12V-G2 supports up to four batteries in parallel for increased capacity. However, total load must not exceed the current limit of a single battery’s BMS. This model is rated for inverters up to 3000W—exceeding this can damage the system.

For larger power demands and advanced configurations, consider upgrading to the Enerdrive Pro Series Power Pack Systems with Active Cell Balancing and full series/parallel integration.
