Frequently Asked Questions


1. What temperature environment should the battery be used in?

Operating batteries at temperatures at or slightly below 25ºC will optimize both performance and life. Higher temperatures also increase the self-discharge characteristic. Colder temperature will lower battery capacity and prolong battery life.


2. What should be pay attention to when using the battery in a humid environment?

Enclosure provides good protection of the cells and circuitry from incidental water spray. However, the seams are not fully sealed and frequent exposure to rain and wet conditions can allow water ingress into the casing, which can corrode the cell terminals and lead to erratic behavior of the BMS circuitry. We suggest covering the battery with a bag when exposed to water spray.


3. Why did the battery run out after storing for a while?

Lithium cells have very low self-discharge, the BMS protection circuit inside the battery pack does draw a little current at all times. Please check the state-of-battery before using it if the battery had been stored without working for over half a year.



Bluetooth APP

1. How to switch to the device that you want to connect

APP will automatically connect with the device of last connection if it is nearby. If you want to switch to different device, you need to select “ Bluetooth Contact ” in the menu, and find the device from the the list.


2. About “Renew”

In the “Bluetooth Connect” interface, if you click the “Renew” button still keeps connected with device, you don't have to connect it again. IOS APP connection will be cut off by IOS, you have to search the device from the device list and select to connect again.


3. Failure Connection

Open again your phone Bluetooth and DT SMART BATTERY APP, Select “ Bluetooth Connect ”on the menu, and find the device ID that you want to connect from the device list.

*If the device is not nearby, connection will fail.


4. Unable to find device ID

Method 1: Turn off the App and Bluetooth, re-activate Bluetooth and the App, select the “ Bluetooth connection ” interface to find the device ID.

Method 2: After charging the battery pack for one hour, restart Bluetooth and App to connect with the battery. If the above two methods cannot help to find the device, you need to contact the manufacturer.


5. Data vary quickly

Based on laboratory test, the battery connection distance between the battery pack and phone is about 9 meters. When the distance is longer than 9 meters or the surrounding environment is complicated, Android App the data may misaligned. Please move near to the battery pack and reconnect the battery pack.
