6.What is the active backup protection?
Active backup protection is a feature that quickly responds to potential risks like overvoltage or overheating, using newly integrated self-control fuses for faster activation compared to traditional fuses, even if other components fail.
7.To ensure the battery’s cycle life, what is the recommended depth of discharge (DOD)?
We recommend not exceeding an 80% depth of discharge (DOD) to ensure optimal battery life.
8.What are the installation requirements for the battery?
●The installation environment should be clean, cool, and well-ventilated. Avoid oil, dirt, or debris to prevent leakage and short circuits.
●Safe operation requires temperatures between -4℉-140℉ (-20℃-60℃), with an ideal range of 59℉ (15℃) to 86℉ (30℃).
●The battery can be installed on its side or vertically, but should not be stacked or placed upside down.
9.How can the battery be connected?
The battery can only be connected in parallel, with a maximum of 8 batteries in parallel.
10.Can the battery communicate with the DC Home APP/Renogy ONE M1/Renogy ONE Core?
Yes, the battery has built-in Bluetooth and can communicate with the DC Home app, Renogy ONE M1, and Renogy ONE Core for easy monitoring and control.
11.Can I use this battery with other brands of batteries in parallel?
No, batteries connected in parallel must be the same brand, type, voltage, and capacity to ensure proper operation.
12.Before connecting the batteries in parallel, are there any principles to follow to make the battery pack charge and discharge balanced?
●Ensure the initial state of the batteries is the same. It’s recommended to fully charge each battery separately and allow them to rest for 30 minutes to ensure a voltage difference of less than 0.1V before connecting.
●Do not parallel old and new batteries with more than a six-month difference in age.
●Follow the wiring guidelines in the product manual for the best configuration.
13.Does the battery automatically enter shelf mode when not used for a long time?
No, the battery does not enter shelf mode automatically when unused. It requires manual activation if needed.
14.What is the self-discharge rate of this battery?
The self-discharge rate of this battery is less than 3% per month.
15.I accidentally over-discharged the battery, resulting in under-voltage protection. What kind of charger should I use to charge the battery?
●Disconnect the wiring cables from the battery immediately.
●Use a charger with lithium activation functionality and charge the battery for more than 24 hours at a temperature above 41°F (5°C). When the terminal voltage rises above 12.4V, the battery will charge normally.
16.What kind of charger should I choose to charge this battery?
●Use a charger specifically designed for 12V LiFePO4 batteries.
●Ensure the charger’s charging parameters match the battery’s specifications.
●The charge current should not exceed the battery’s maximum continuous charging current of 100A.
●The charger should have protection features for reverse polarity, overcurrent, overvoltage, and overtemperature.
17.Does the battery have a self-heating function? If so, what are the working conditions of the battery's self-heating function?
Yes, the battery includes a self-heating function.
The working conditions of the battery's self-heating function are shown below:
●The self-heating function activates automatically when the battery temperature drops below 41°F (5°C) and requires a stable charge current of at least 6A. It stops when the temperature exceeds 50°F (10°C).
●The heating process raises the temperature by approximately 46.4°F (8°C) per hour when running at full power (85W).
18.How do I store the battery?
To store the battery properly:
●Charge the battery to 30%-50%.;
●Disconnect the battery from the system;
●Do not expose the battery to direct sunlight, moisture, or precipitation;
●Store it in a dry, well-ventilated, clean area away from direct sunlight, moisture, or precipitation.
●Ensure temperatures range from -13℉ to 149℉ (-25℃ to 65℃).
●Handle the battery carefully to avoid sharp impacts or pressure on the casing.
●Charge the battery at least once every 3-6 months to prevent overdischarge. When removed from storage, fully charge it.
