The above values are from the NEC Table 310.15(B)16 for copper cables rated at 75°C (167°F), operating at an ambient temperature of no more than 30°C (86°F). Lengths in excess of 6 feet (1829 mm) may require heavier gauge cable to avoid excess voltage drop in undersized wiring.

Connecting Batteries in Bank

Warning:

DO NOT connect batteries in series. Doing so can cause catastrophic failure.

Caution:

DO NOT connect batteries with different chemistries, rated capacities, nominal voltages, brands, or models in parallel.
Please avoid excessive voltage difference between parallel connected batteries to avoid triggering the over-current protection.
The cables between each parallel connected battery should be of equal length to ensure that all batteries can work equally together.
DO NOT connect more than 8 batteries in parallel.

To connect multiple batteries in parallel, first connect the Positive Terminals of the batteries to each other. Then, connect the Negative Terminals of the batteries to each other. Finally, connect the Positive Terminal of the first battery and the Negative Terminal of the last battery to the system. This type of arrangement is used to increase the overall battery capacity while keeping the battery voltage the same.

Securing Cable Connections

Caution:

Please secure all cable connections to the proper specification in order to ensure good contacts between the cable lugs and the battery terminals. Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
Please use an insulated wrench to tighten the cable connections.

To ensure good contacts between the cable lugs and the battery terminals, please use the appropriate number of washers to allow for as much thread engagement as possible without bottoming out the terminal bolt. The correct number of washers can be determined by hand-tightening the terminal bolt with just the cable lug in place and observing the gap that is present. Use the number of washers needed so that the washer stack is slightly larger than the observed gap.

It is important to ensure that the cable lug and the top surface of the terminal are in contact.

The washer(s) must be placed on top of the lug. Do not place the washer(s) between the battery terminal and the cable lug as this can cause high resistance and excessive heating.

Note:

Please use the included Long Terminal Bolts when needed to secure multiple cable lugs on a single battery terminal.

Installation Environment

The battery should be installed in a clean, cool, and dry place, keeping water, oil, and dirt away from the battery. The accumulation of these materials on the battery can cause current leakage, resulting in self- discharge and a possible short-circuit. Sufficient air flow must be provided to prevent excessive heat build-up and to minimize temperature variation between the paralleled connected batteries.

Battery Operation

Caution:

DO NOT overcharge or over discharge the battery.
DO NOT charge the battery at low temperatures below 0°C (32°F) and discharge the battery at high temperatures above 140°F (60°C).

Activating Battery

The battery is shipped in shelf mode. Before using the battery for the first time, please activate the battery with a charge/discharge current greater than 1A and measure the terminal voltage to validate. Prior to long periods of storage, please disconnect the battery from the system.

The battery will enter shelf mode automatically after 24 hours. In shelf mode, the battery has a low self-discharge rate and can hold the charge for a longer period of time.

Note:

Parallel connected batteries can be activated simultaneously with a charge/discharge current greater than 1A for each battery.

Charging Battery

Caution:

DO NOT exceed the maximum continuous charge current of the battery.
Only charge the battery with a battery charger or charge controller that is compatible with the lithium iron phosphate battery

Note:

Depending on the length of time between manufacturing and shipping, the battery may be received at a partial state of charge (SOC). Please fully charge the battery prior to the initial use.
During the standard charging process, the battery is first charged at a constant current of 60A until the battery voltage reaches 14.4V. Then, the battery is charged at a constant voltage of 14.4V while tapering the charge current. The standard charging process is considered complete when the charge current is less than 10A. However, leaving the battery on float will continue to balance the battery cells and will not damage the battery. The standard charging process normally takes 3.5 hours. Safe charging requires battery temperatures between 32°F and 131°F (0°C and 55°C).

Discharging Battery

Caution:

DO NOT exceed the maximum continuous discharge current of the battery.
DO NOT connect large loads to the battery when it is running low
If the battery shuts off due to low state of charge (SoC), please disconnect the battery from loads and charge the battery as soon as possible. Failure to do so may cause irreversible damage to the battery.
It is recommended to pair the battery with discharge equipment featuring low voltage disconnect.
During the standard discharging process, the battery is discharged at a constant current of 60A until the battery voltage reaches 10V. Safe discharging requires battery temperatures between -4°F and 140°F (-20°C and 60°C).

Battery Maintenance

Inspection

Please perform regular inspections following the steps below:

Examine the external appearance of the battery. The top of the battery and terminals should be clean, dry, and free of corrosion.

Note:

The warning status can only be monitored on the DC Home app.
The warning status will not affect the normal operation of the battery. But it is recommended to pay closer attention to the battery to avoid triggering protections.

Battery Cell Balancing

The battery employs bypass circuit to maintain the balance between each battery cell group. Each battery cell group is connected with a bypass resistor and a switch in parallel. During the charging process, if the highest-voltage battery cell group reaches the set balancing starting voltage and the voltage difference between the highest-voltage and the lowest-voltage battery cell group exceeds the set voltage difference, the switch connected to the highest-voltage battery cell group will be closed to shunt the charge current around the highest-voltage battery cell group through the bypass resistor until the voltage difference drops below the set value. To avoid excessive energy loss, the battery cell balancing is only performed during the charging process.

Troubleshooting

If any problems occur during the battery operation, please refer to the following instructions or contact us for assistance:

If the battery is unable to be activated with a charge/discharge current greater than 1A or the battery is activated with a resting voltage below 10V, the battery may have been severely overdischarged due to self-discharge or parasitic loads. Please revive the battery with a battery charger or charge controller featuring lithium battery activation or force charging.
If the battery voltage is 0V, the internal fuses may have blown due to severe over current. Please contact us for assistance.
If the battery shuts off due to undervoltage protection, please disconnect the battery from loads and charge the battery with a current greater than 1A as soon as possible.
If the battery cuts off the charge current due to overvoltage protection, please disconnect the battery from the charging source and discharge the battery with a current greater than 1A as soon as possible. If the problem persists with a lithium iron phosphate compatible charging source and the correct voltage setting, please first reduce the charge voltage by 0.2V~0.4V to balance the battery cells for 6 hours before attempting to fully charge the battery again.
If the battery temperature gets too high/low during the operation and triggers the high/low temperature protection, please disconnect the battery from the charging source and/or loads and cool down/warm up the battery. The battery will automatically recover from the high/low temperature protection and continue operating.
If too high a current passes through the battery and triggers the charge/discharge over-current protection, please disconnect the battery from the charging source/loads as soon as possible.
The battery will automatically recover from the charge/discharge over-current protection after 1 minute. If the charge/discharge over-current protection is triggered 3 times in a row, the battery will no longer recover automatically. Please discharge/charge the battery with a current greater than 1A to recover the battery from the charge/discharge over-current protection.
If the battery is shorted and triggers the short circuit protection, please remove the short circuit as soon as possible and charge the battery with a current greater than 1A. The battery will automatically recover from the short circuit protection.
