Owner's Manual for Enerdrive B-TEC Lithium Battery

Quick guide from the manual

The Enerdrive B-TEC Lithium (LiFePO4) battery is designed for deep cycle applications with integrated smartphone monitoring. Key operational requirements include using a compatible LiFePO4 charger, ensuring proper cable sizing for inverter loads, and maintaining the battery in a dry, cool, and upright position. If the battery shuts down due to low voltage, a reset procedure is required to restore power.

Installation

The battery must be installed in a dry and cool location. Enerdrive recommends the following installation guidelines:

• Orientation: Install in an upright position.
• Clearance: Maintain at least 25mm of clear space around the battery.
• Mounting: Use supplied battery trays and straps with sufficiently rated fasteners.
• Prohibited Areas: Do not install in vehicle engine bays, high heat environments, wet areas (e.g., boat decks, open ute trays), or compartments dedicated to gas storage.
• Safety: Avoid mounting near metallic service lines (LPG, diesel, petrol) to prevent accidental shorting.

Connections

Proper connection is critical for system safety and performance:

• Terminals: It is recommended to connect no more than four terminals to a battery terminal. Use a fuse block and negative busbar if more connections are required.
• Cable Sizing: Use cables of adequate size for system demands. Examples: 1000W Inverter (35mm²), 2000W Inverter (70mm²), 3000W Inverter (95mm²).
• Hardware: Use spring washers on terminal bolts to apply pressure to lugs. Ensure the main battery cable lug is mounted directly onto the battery terminal with no washers between them.

Charging

Lithium batteries require specific charging profiles to ensure longevity:

• Charger Type: Must use a charger with a lithium LiFePO4 setting (AC chargers, DC to DC chargers, or solar controllers).
• Voltage Settings: Set charge voltage to 14.2 - 14.6V and float voltage to 13.5 - 13.6V (for 12V models).
• Prohibited: Do not use chargers with "Pulse Stage" or "Equalisation Mode". Do not connect directly to an alternator or a VSR (Voltage Sensitive Relay).

Restarting Your Battery

If the DC system shuts down due to the internal low voltage disconnect, follow this procedure:

1. Turn off all DC and AC loads.
2. Connect charging source(s) and switch ON.
3. Hold the "Reset" button for 5 seconds, release, and perform a quick press.
4. Release and wait 7 seconds.
5. Power will be restored and charging will commence after a few seconds.
6. Once the State of Charge (SOC) is above 20%, loads can be switched on.

Using the Smart Phone Battery Monitor App

The battery incorporates a wireless monitoring system. Download the Android or Apple app to monitor capacity, voltage, current, SOC, state of health, temperature, and alarms. The red warning light on the app is an indicator, not necessarily a fault condition. The default password to change the Bluetooth name is 1234.

Warnings

• Do not use for cranking/starting applications.
• Do not connect batteries in series.
• Do not disassemble the battery.
• If the battery emits a peculiar smell, heating, or distortion, stop using it immediately.
• If the battery leaks and gets into eyes or on skin, rinse with clean water and seek medical attention.
