Enerdrive EPL-125BT-12V Battery: Full Visibility with Bluetooth Monitoring

Stay on top of your power usage and battery health with Enerdrive’s integrated Bluetooth Smart Monitoring System. Compatible with Android™ and Apple® devices, the mobile app gives you real-time access to:

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

The internal Battery Management System (BMS) ensures safe operation at all times, protecting against overcharging, deep discharging, high temperatures, and short circuits. If fully discharged, the G2’s built-in reset button lets you reboot the battery—no external voltage required.

Enerdrive Lithium Battery EPL-125BT-12V vs AGM: More Power, Less Weight

This lithium battery packs serious efficiency gains over traditional lead-acid batteries:

• 125Ah Lithium = 200Ah AGM Equivalent
• Delivers over 2500 cycles at 80% DoD
• 60% more usable power
• Approximately 50% lighter and 30% smaller than AGM batteries

This makes the EPL-125BT-12V ideal for space- and weight-restricted installations, without sacrificing power or performance.

Installation Notes, Inverter Limits & System Scalability

This battery is intended for internal use only and must not be installed in engine bays, wet areas, or gas compartments. It can be safely paralleled with up to four other identical B-TEC batteries, but system loads must remain within the current limit of a single battery's BMS. The EPL-125BT-12V supports inverter capacities up to 1000W—exceeding this may damage the BMS.

Need more power than a single battery can deliver? Upgrade to the Enerdrive Pro Series Power Pack Systems, offering series and parallel battery configurations with Active Cell Balancing for complete system control and safety.
