Introduction

The Ecox 12200 is a smart lithium iron phosphate battery module designed to replace deep cycle lead-acid batteries. With a standard BCI 4D size, it is ideal for recreational vehicles (RV), marine applications, trucks, cabins, and other off-grid deep-cycle applications.

Advantages:

• High Reliability: Features advanced BMS with comprehensive protection functions.
• Long Cycle Life: Utilizes Energy Storage Grade LiFePO4 cells, offering over 8 times the cycle life of lead-acid batteries.
• High Energy Density: 50% lighter than equivalent lead-acid batteries and 70% the size of regular lithium batteries of equivalent energy, making it easier to carry, faster to charge, and more convenient to use.
• Flexible Connection: Available in 12V, 24V, 36V, and 48V configurations. Multiple batteries can form a system with up to 40.96 kWh energy output through parallel and series connections.
• Strong Environmental Adaptability: Includes a low-temperature smart heating function for safe charging in sub-zero temperatures.
• Real-time Monitoring: Battery status can be monitored via a dedicated App.
• Low Self-discharge Loss: Can be stored for over 2 months when turned off after full discharge, and over 6 months when turned off at 40%-70% charge.

Battery Installation

4.1 Tools and Accessories Preparation

The following tools and accessories are required for installation:

• Battery
• Insulating Cap × 2
• Terminal Bolt (M8 × 1.25 × 14 mm) × 2
• Volt meter
• Torque Wrench
• Wire Cutter
• Screwdriver
• Insulating Gloves
• Safety Goggles
• Bus Bar (for multiple battery connections)

4.2 Pre-installation Check

• Ensure the battery is away from open flames, heat sources, and flammable materials. [No Fire Symbol]
• Cut off power before wiring, installing, or removing the battery. [Power Off Symbol]
• To prevent electric shock, remove watches, bracelets, rings, and other conductive items. Wear insulating gloves and safety goggles. [Gloves Symbol] [Goggles Symbol]

4.3 Battery Connection

4.3.1 Single Battery

Connect the battery terminals using the provided terminal bolts and insulating caps. Ensure the torque is 9 ± 1 N·m.

External devices like chargers, MPPT controllers, and inverters can be connected to the battery.

4.3.2 Multiple Batteries

Batteries can be connected in series and parallel to increase voltage and capacity.

Caution:

• Before series connection, ensure the voltage difference between batteries is less than 0.1 VDC. For parallel connection, ensure the difference is less than 0.5 VDC. Balance voltage if necessary to prevent over-current protection triggers.
• Do not mix batteries of different brands, types, models, or lifespans.
• To prolong battery life, ensure power cables have the same length, diameter, and internal resistance when connecting multiple batteries.

Note:

• Refer to Section 5.3.1 for terminal and external device connection details.
• When connecting batteries in series and parallel, using a busbar is recommended for effective power distribution.
• The provided connection methods are for reference; optimal methods may vary based on cable size, connected equipment, and environmental conditions.

Connecting Batteries in Parallel

Connect batteries in parallel by connecting positive terminals to positive terminals and negative terminals to negative terminals. Up to 8 batteries can be connected in parallel.

Voltage Balance: Charge batteries separately until the voltage difference is ≤ 0.1 VDC. Then, connect in parallel and fully charge, followed by a 24-hour float charge.

Connecting Batteries in Series

Connect batteries in series by connecting the positive terminal of one battery to the negative terminal of the next.

Note:

• Up to 4 batteries can be connected in series.
• Long-term series connection may lead to imbalances. It is recommended to periodically connect batteries in parallel and float charge them for 24 hours after a full charge.

Connecting Batteries in Series & Parallel

Combine series and parallel connections to achieve desired voltage and capacity configurations.

4.4 Post-Installation Check

Verify that the positive and negative connections are correct. [Checkmark Symbol]

Battery Activation

Before first use, activate the battery using a charger with a current greater than 1 A. Verify successful activation by measuring the battery voltage.

Troubleshooting

My battery won't turn on?

• Check if the charger is connected properly.
• If yes, check if the charger output is normal.
• If no, contact your distributor.

My battery won't turn off?

Disconnect all external devices. The battery will turn off after 24 hours of inactivity.

My battery won't charge?

• Over-voltage / Over-current: Check if the charger specification is within the rated range. If yes, restore the battery by discharging. If no, change the charger.
• Over-temperature / Under-temperature: Wait for the battery temperature to return to the working temperature range.

My battery won't discharge?

• Low Power: Disconnect all external devices and charge the battery in time. If yes, restore the battery by charging it. If no, change the charger.
• Over-current: Check if the total current of all external devices is within the rated range. If yes, restore the battery by charging it. If no, change the charger.
• Over-temperature / Under-temperature: Wait for the battery temperature to return to the working temperature range.
• Short Circuit: Check if the external device is short-circuited. If yes, disconnect the external devices and see if the battery can discharge. If the battery still cannot discharge, restore it by charging it.
