What is the cycle life of this battery?
(0.5C,25℃): 80%DOD 2000 Cycles
What is the grade and type of cell inside this battery?
The internal cells of this battery are Square prismatic cells, which is class A cell.
To ensure the battery cycle life, what is the recommended depth of discharge (DOD)not to exceed?
Do not exceed 80%
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.
- Safe operation requires environment temperatures between-4℉-140℉(-20℃-60℃). The recommended operating environment temperature range is 59°F (15°C) and 86°F (30°C).
- At the same time,need to place the battery upright or horizontally on the long side, not stacked or upside down.
Can I connect the batteries in series or in parallel?
The battery can only be connected in parallel, the recommended maximum number of parallel connections is 8.
What is the IP protection rating of the battery?
IP65
Can the battery communicate with the DCHomeAPP?
Yes, the battery has built-in Bluetooth, and can communicate with DC Home APP via Bluetooth.
Can I use this battery with other brands of batteries in parallel?
No. The batteries connected in parallel that need to be the same brand, same type, same voltage and same capacity.
When the batteries are connected in parallel, those principles need to be followed to make the parallel battery charge and discharge balanced?
- The initial state of the parallel battery should be the same, if the parallel battery is the same type, the same brand, the same voltage, the same capacity, it is generally recommended to fully charge the battery alone, the battery rests for half an hour, the open circuit voltage between the batteries is less than 0.1V before using in parallel.
- The maximum number of parallel-connected batteries should not exceed 8.
- The time interval between the old and new batteries in parallel should not exceed six months.
- It is recommended that the wiring of parallel batteries be wired according to the following wiring diagram, and make sure that the wiring cable specifications and length between parallel batteries are the same, and that the wiring connections are tightened.
Does the battery automatically go into Self mode when it is not used for a long time?
Yes, in order to low self-discharge rate, the battery is not used for more than 24 hours; otherwise, the battery will enter Self mode. When the battery is in this state, the battery internal BMS and built-in Bluetooth will be turned off. At this time, as long as battery charging and discharging current greater than 1A, the battery will soon be activated (the battery is not in a protected state such as under-voltage protection), the battery internal BMS and built-in Bluetooth will also be turned on.
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 battery charging parameters
- Charge current is less than the maximum continuous charging current of 100A for the battery
- With reverse polarity, overcurrent, overvoltage and overtemperature protection functions
Can I use these batteries in parallel together that I bought different firmware version of the same SKU batteries? Do I need to upgrade the battery firmware version?
You don't need to upgrade the battery firmware version, batteries of the same SKU with different firmware versions can be used together in parallel.
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 wires from the battery.
- Use a charger that matches the battery and has a lithium-ion activation function to activate and charge the battery at an ambient temperature of 41°F or higher (below 131°F), and when the voltage at the battery terminal is restored to 12.4V or higher, the battery can be charged normally
How do I store the battery?
Please follow the tips below to ensure that the battery emerges from storage 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 sharp impacts or extreme pressure on the battery housing.
- Charge the battery at least once every 3 months to prevent it from overdischarge.
- Fully charge the battery when it is taken out of storage;
