Product features：
1. Cell phone app monitors the battery charging and discharging status. Single battery overvoltage and under-voltage, battery pack overvoltage and under-voltage, balance voltage, high and low temperature, and release value can be adjusted.
2. The communication module is connected to computer to monitor the battery data, set parameters, read BMS communication protocol and communicate with the device.
3. Imported IC software and hardware dual protection. Software running real-time monitoring program plus secondary protection. Sleep and low standby power consumption, high-quality electronic components.
4. It calculates the remaining capacity and charge capacity of the battery based on the current versus time score.
5. Temperature control detection: BMS built-in balanced power temperature control to detect. Adjustable high and low temperature protection function, the temperature sensor is strong and not easy to break.
6. App display interface has speed measurement function. It can accurately detect the speed based on Hall pulse and calculate the remaining mileage.
7. It supports Bluetooth, UART communication.
The differences are as follows:
1)Bluetooth APP is suitable for cell phone to view and adjustable parameters.
2)UART module is suitable for viewing and adjustable parameters on the computer.
3) We will send you a Bluetooth module after ordering so you don't need to buy additional Bluetooth.
4) The order only include Bluetooth module. it's not include UART module. if you need an UART module please contact us to purchase.
8. APP software reference interface display:
01) Percentage capacity
02) Temperature
03) Charge time
04) Total voltage
05) Remaining capacity
06) Power
07) Voltage range
08) Voltage diff
09) Charging turn on / off
10) Discharge turn on / off
11) Protection state
12) Cell balance
13) Each cell voltage
14) Nominal capacity
1. Using app for the first time, please change nominal capacity to actual capacity, cycle capacity is actual capacity * 0.8
