1.What is the cycle life of this battery?
(0.5C/1C, 25℃): 5000 Cycles (80% DOD, 80% EOL)
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 battery cell (Class A).
3. To ensure the battery cycle life, what is the recommended depth of discharge (DOD)?
The battery is not advised to discharge over 80% of its capacity.
4.How are the cells inside the battery connected?
The cells inside the battery are connected in 4S2P.
5. What is the installation requirements for the battery?
●The battery installation environment is clean, cool, and well-ventilated. Keep the battery away from oil and dirt. The accumulation of these substances can cause current leakage, resulting in self-discharge, and a possible short circuit.
●Safe operation requires environment temperatures between -4℉-140℉(-20℃-60℃). The recommended operating environment temperature range is 59°F (15°C) to 86°F (30°C)
●At the same time, the battery should not be stacked on top of each other or installed upside down.
6. How can the battery be connected?
The battery can be connected in series (up to 4) or in parallel (up to 8) or in series-parallel (up to 4S4P).
7. What is the IP protection rating of the battery?
IP65
8. Can the battery communicate with the DC Home APP/Renogy ONE M1/Renogy ONE Core?
The battery does not have built-in Bluetooth or an external communication port, so the battery does not have the external communication functionality. Therefore, it cannot communicate with DC Home App/Renogy ONE M1/Renogy ONE Core.
9. Can I use this battery with other brands of batteries in series or in parallel or in series-parallel?
No, the batteries connected in series or in parallel or in series-parallel need to be the same brand, same type, same voltage, same capacity.
10. Before connecting the batteries in parallel or in series or in series-parallel, are there any principles to follow to make the battery pack charge and discharge balanced?
●The initial state of the batteries should be the same. It is generally recommended to fully charge the batteries separately. Then the batteries are left to stand for half an hour. After the difference in the open circuit voltage between the batteries is less than 0.1V, the batteries are connected in series or in parallel or in series-parallel. At the same time, the batteries are connected in series or in parallel or in series-parallel for 24 hours, then the battery pack is connected to the system;
●The time interval between the old and new batteries in series or in parallel or in series-parallel should not exceed six months.
●It is recommended that the wiring cables between series or parallel or series-parallel batteries are wired according to the content of the battery product manual.
11. Does the battery automatically enter the Shelf Mode when it is not used for a long time?
No, the battery will not enter the Shelf Mode when it is not used for a long time.
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 choose the following chargers:
●match 12V LFP battery;
●match charger charging parameters with the battery charging parameters;
●the charge current is less than the maximum continuous charging current of the battery (100A);
●the charger with reverse polarity, overcurrent, overvoltage and overtemperature protection functions
14. I accidentally over-discharged the battery, resulting in the battery under-voltage protection. What kind of charger should I use to charge the battery?
●Remove all the wiring cables on the battery;
●Use the charger that matches the battery and has a lithium activation function to activate and charge the battery for more than 24 hours at the ambient temperature of above 41°F (below 131°F), and when the terminal voltage of the battery is restored to above 12.6V, then the battery will be charged normally.
15. How do I store the battery?
Please follow the tips below to ensure that the battery is stored in a good condition:
●Charge the battery to 30%-50%;
●Disconnect the battery from the system;
●Store the battery in a well-ventilated, dry, clean area with temperatures between -13℉-149℉(-25℃-65℃);
●Handle the battery carefully to avoid impacts or extreme pressure on the battery housing;
●Charge the battery at least once every 3~6 months to prevent it from overdischarge;
●Fully charge the battery when it is taken out of storage.
