What is the cycle life of this battery?
(0.2C,25℃): 80%DOD 4000 Cycles
To ensure the battery cycle life, what is the recommended depth of discharge (DOD) not to exceed?
Do not exceed 80%
What is the grade and type of cell inside this battery?
The internal cells of this battery are soft pack cells, which is class A cell.
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°F (-20°C) - 122°F (50°C). The recommended operating environment temperature range is 59°F (15°C) and 86°F (30°C).
- At the same time, 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 4.
What is the IP protection rating of the battery?
IP54
Can the battery communicate with the DC Home APP?
Yes. Use BT-2 (sold separately) to connect to the battery UP communication port, and then the battery and DCHomeAPP can communicate 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 4.
- 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?
No. You need to use the activation switch to connect to the UP communication port of the battery and press and hold the activation switch for 3s to put the battery into Self mode, thus keeping the low self-discharge rate of the battery.
What is the self-discharge rate of this battery?
- Battery is in active state, battery self-discharge current＜40mA.
- Battery is in self mode, battery self-discharge current﹤100μA.
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 50A 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.
- Turn the battery off with the activation switch.
- Store the battery in a well-ventilated, dry, clean area with temperatures between -13°F (-25°C) - 149℉ (65°C).
- 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;
