Secure with mounting screws at 14.16 in-lbs (1.6 N·m).

Installation Steps

Step 1. Plan a Mounting Site

Install the battery in a clean, cool, and dry location, free from water, oil, or dirt to prevent current leakage, self-discharge, and short-circuiting.

Ensure sufficient airflow to prevent heat build-up and minimize temperature variation.

Environmental Conditions:

• KEEP DRY ?
• FRAGILE ⚠️
• VENTILATION ?️

Temperature Ranges:

• Charge: -4°F to 131°F (-20°C to 55°C)
• Discharge: -4°F to 140°F (-20°C to 60°C)

Humidity: 10%-95%

Step 2. Wear Insulating Gloves

Wear insulating gloves during installation.

Step 3. Check the Battery

Inspect for visible damage (cracks, dents, deformation). Ensure connector contacts are clean, dry, and free of corrosion.

CAUTION: Do not touch exposed electrolyte or powder if the battery is damaged. Flush skin/eyes immediately with water and seek medical attention.

Step 4. Install Battery Terminals

Attach battery adapter cables using Terminal Bolts, Spring Washer, and Flat Washer. Ensure proper contact and torque.

Torque: 70.8 in-lbs (8 N•m)

WARNINGS:

• Ensure cable lug and terminal surface are in contact. Do not place washers between terminal and lug.
• Avoid short-circuiting terminals.
• Verify polarity before wiring.
• Do not touch terminals with bare hands.
• Follow torque specifications to prevent terminal breakage or meltdown. Use Long Terminal Bolts for multiple cable lugs.

Step 5. Connect the Battery to Other Devices

WARNING: Use appropriately sized circuit breakers, fuses, or disconnects certified by a qualified electrician.

For a Single Battery

Connect the battery to an inverter, DC-DC charger, DC distribution panel, or charge controller using appropriate wiring and a battery fuse.

For Batteries in Parallel

Connect batteries in parallel using busbars for efficient power distribution.

Calculate Voltage and Current in Parallel Connections

Connecting multiple 12.8V 200Ah batteries in parallel results in:

• System Voltage: 12.8V
• System Current: Sum of individual battery currents

Example: 4 x 12.8V 200Ah batteries = 12.8V 800Ah system.

NOTE: This battery is designed for parallel use only. Use long terminal bolts (M8 * 1.25 * 16 mm) with a torque of 70.8 in•lbs (8 N•m).

WARNINGS:

• Do not connect batteries with different chemistries, capacities, voltages, brands, or models in parallel or series.
• Avoid connecting batteries purchased more than six months apart.
• Ensure all cables between batteries are of equal length.

Balance Batteries Prior to Connection

Balance batteries to reduce voltage differences and optimize performance:

1. Charge each battery individually to full capacity.
2. Measure each battery's voltage with a voltmeter. Keep the difference below 0.1V.
3. Connect batteries in parallel and allow them to rest for 12 to 24 hours.

NOTE: Rebalance battery voltages every six months. Slight voltage differences may occur over time.

Parallel Connection – Installation Steps

Use suitable busbars for high currents. Cable connection methods are for reference; consider cable size, equipment, and environment.

Battery Cell Balancing

The battery uses a bypass circuit with a resistor and switch to balance battery cell groups. During charging, if the highest-voltage cell group reaches the balancing voltage and the difference exceeds the set value, the switch closes, shunting current through the bypass resistor until the voltage difference normalizes. Cell balancing occurs only during charging to minimize energy loss.

Step 2: Pair the battery with the DC Home app.

Monitor battery parameters via the app.

Charging/Discharging Parameter Settings

Charge

Discharge

Battery Charging and Discharging Logic

The battery may be received at a partial state of charge (SOC). Fully charge before initial use. If the battery shuts off due to low SOC, disconnect from loads and charge immediately to prevent irreversible damage.

Charging Logic

The standard process involves charging at a constant current of 100A until voltage reaches 14.4V, then constant voltage charging at 14.4V with tapering current. Charging is complete when current drops below 10A (tail current). This process takes approximately 2.5 hours and requires temperatures between 32°F and 131°F (0°C to 55°C).

NOTE: Lithium batteries are compatible with MPPT, AC, and DC-DC chargers. Set charge/boost/bulk voltage to 14.4V (±0.2V).

WARNINGS:

• Do not overcharge or overdischarge.
• Do not discharge at temperatures above 140°F (60°C).
• Use only chargers compatible with lithium iron phosphate batteries.
• Do not exceed the maximum continuous charge current (200A).

Discharging Logic

During standard discharging, the battery delivers a constant current of 100A until voltage drops to 10V. Battery temperature should be between -4°F (-20°C) and 131°F (60°C) for safe discharging.

NOTE: Use discharge equipment with low voltage disconnect (LVD). Do not connect large loads when the battery is low.

WARNING: Do not exceed the maximum continuous discharge current (200A).

How to Estimate the Battery SOC?

SOC values are estimated based on open circuit voltage after 30 minutes rest:

NOTE: Table is for reference; slight variations may occur.

Self-Heating Function

The self-heating function requires a charge current greater than 6A per battery. It activates automatically when the battery temperature drops below 41°F (5°C) and stops when it rises above 50°F (10°C). Temperature rise is approx. 46.4°F (8°C) per hour at 85W (6A).

Battery Management System

The BMS offers over 60 fault alarms and protections:

Operation Parameters

Maintenance & Storage

Inspection

• Examine external appearance: housing and terminals should be clean, dry, and free of corrosion.
• Check battery cables and connections. Replace damaged cables and tighten loose connections.

NOTE: Corrosion can cause increased resistance. Apply insulation grease to terminals for a moisture-resistant seal.

Cleaning

• Disconnect the battery from the system.

• Keep the area around the battery clean.
• Reconnect the battery to the system.

Checking Voltage

Periodically check battery voltage. If unable to activate with >1A current or activated at <10V open circuit voltage, the battery may be severely overdischarged. Stop use until the fault is corrected and the battery can be charged.

Storage

• Charge the battery to 30%-50% SOC.
• Disconnect the battery from the system.
• Store in a well-ventilated, dry, clean area between -13°F (-25°C) and 149°F (65°C).
• Avoid direct sunlight, moisture, or precipitation.
• Handle carefully to avoid impacts or pressure.
• Charge every 3-6 months to prevent overdischarge.
• Fully charge when taking out of storage.
