1.What is the cycle life of this battery?
The cycle life of this battery is 5000 cycles (0.5C/1C, 25°C) with an 80% depth of discharge (DOD) and 80% end-of-life (EOL) capacity.
2. What is the grade and type of cell inside this battery?
The internal cells of this battery are square prismatic cells, which are EV-grade (Class A) lithium-ion battery cells.
3. To ensure the battery cycle life, what is the recommended depth of discharge (DOD)?
It is recommended not to discharge the battery beyond 80% of its capacity to maximize its cycle life.
4.How are the cells inside the battery connected?
The cells inside the battery are connected in a 4S2P configuration (four cells in series, two in parallel).
5. What are the installation requirements for the battery?
The battery installation environment should be clean, cool, and well-ventilated. Keep the battery away from oil and dirt, as these can cause current leakage, self-discharge, and potential short circuits.
Safe operation requires environmental temperatures between -4°F and 140°F (-20°C to 60°C), with an ideal range of 59°F (15°C) to 86°F (30°C).
The battery should not be stacked or installed upside down.
6. How can the battery be connected?
The battery can be connected in series (up to 4), in parallel (up to 8), or in series-parallel (up to 4S4P) for greater capacity and voltage.
7. What is the IP protection rating of the battery?
The battery is rated IP65, meaning it is protected against dust and water splashes.
8. Can the battery communicate with the DC Home APP/Renogy ONE M1/Renogy ONE Core?
No, this battery does not have built-in Bluetooth or an external communication port, so it cannot communicate with the DC Home App, Renogy ONE M1, or Renogy ONE Core.
9. Can I use this battery with other brands of batteries in series, parallel, or series-parallel?
No, batteries connected in series, parallel, or series-parallel must be of the same brand, type, voltage, and capacity to ensure balanced performance.
10. Before connecting the batteries in parallel, series, or series-parallel, are there any principles to follow for balanced charging and discharging?
Ensure the initial state of the batteries is the same. Fully charge the batteries separately and leave them to rest for 30 minutes. If the open circuit voltage difference is less than 0.1V, connect them in series, parallel, or series-parallel.
Follow the wiring instructions in the battery manual for optimal connections.
Batteries connected in series, parallel, or series-parallel should not have a time gap of more than six months between old and new batteries.
11. Does the battery automatically enter shelf mode when not in use for a long time?
No, the battery does not automatically enter shelf mode. It will need to be manually maintained if stored for long periods.
12. What is the self-discharge rate of this battery?
The self-discharge rate of this battery is less than 3% per month.
13. What kind of charger should I choose to charge this battery?
You should select a charger that:
Matches 12V LFP battery specifications
Has charging parameters that match the battery's requirements
Provides a charge current less than the battery’s maximum continuous charging current of 100A
Features reverse polarity, overcurrent, overvoltage, and overtemperature protection functions
14. I accidentally over-discharged the battery, resulting in under-voltage protection. What kind of charger should I use to charge the battery?
Disconnect all wiring cables from the battery.
Use a charger with a lithium activation function that matches the battery. Charge the battery for more than 24 hours at an ambient temperature between 41°F (5°C) and 131°F (55°C). Once the terminal voltage rises above 12.6V, the battery will charge normally.
15. How do I store the battery?
To store the battery properly:
Charge it to 30%-50%
Disconnect it from the system
Store in a dry, well-ventilated, clean area with temperatures between -13°F and 149°F (-25°C to 65°C)
Handle the battery carefully to avoid impacts or extreme pressure on the casing
Charge the battery at least once every 3 to 6 months to prevent overdischarge.
Fully charge the battery when it is taken out of storage.
