FAQ
Q: What is the best way to check the battery's performance and current status?
>
The best way to check the battery's performance and status is by using the Bluetooth connectivity feature, which allows you to monitor the battery's voltage, current, charge level, and health directly via the mobile app (OKMO Bluetooth App). You can also check the battery’s internal protection system and make adjustments as needed.
Q: What are the steps to follow after receiving a new battery?
>
1. Inspect the battery for any physical damage during shipping.
2. Ensure the battery is at a safe voltage level for first use (if necessary, charge it to an optimal level).
3. Download the OKMO Bluetooth App to monitor the battery.
4.Connect the battery to your system (solar, off-grid, etc.) or device following manufacturer guidelines.
5. Start using the battery, ensuring it's placed in a well-ventilated area.
Q: Does this battery include features to protect against low temperatures?
>
Yes, OKMO's lithium batteries are equipped with an internal Battery Management System (BMS) that offers temperature protection. This includes protection against low and high temperatures, which helps prevent damage to the battery and ensures it operates efficiently in various environmental conditions.
Q: What is the maximum number of batteries I can connect in series or parallel?
>
The maximum number of batteries that can be connected in series or parallel depends on your specific configuration and the voltage requirements of your system. For example, when connecting in series, ensure the total voltage does not exceed the maximum voltage rating for your system. In parallel, you can connect multiple batteries to increase capacity, but ensure they are of the same type and voltage to avoid imbalances.
Q: What is the recommended method for charging a OKMO 12V 100Ah Bluetooth lithium battery?
>
The recommended charging method is to use a compatible lithium battery charger designed for 12V lithium batteries. Always use a charger with a proper charge profile (constant current/constant voltage) for lithium batteries. The charging voltage should be around 14.6V, with a maximum charge current that doesn’t exceed the battery's rated charging current (e.g., 0.2C or 20A for a 100Ah battery). Avoid overcharging or undercharging.
Q: How do Group 24 and Group 31 batteries differ in size and functionality?
>
Group 24 batteries are generally smaller (approximately 10.25 x 6.75 x 8.75 inches) and are used in applications like RVs, marine, and some solar systems.
Group 31 batteries are larger (approximately 12.2 x 6.8 x 8.8 inches) and provide more power capacity, making them ideal for larger setups like buses, boats, and larger solar systems.
Functionality-wise, Group 31 batteries tend to have a higher capacity, meaning they can store more energy and provide longer runtimes.
Q: Is it possible to install the battery in a non-upright position?
>
It is generally recommended to install lithium batteries like OKMO's in an upright position to avoid potential leakage or performance issues. However, some models may support installation in other orientations as long as they are kept within the manufacturer's guidelines for ventilation and safety. Always consult the product manual for specific installation instructions.
Q: Where can I find and download the OKMO Bluetooth App to manage my battery?
>
The OKMO Bluetooth App can be downloaded from both the Apple App Store (for iOS devices) and Google Play Store (for Android devices). You can search for "OKMO" in the respective app store to find and install the app, which will allow you to monitor and manage your battery's status and performance."
