The lithium battery protection board is the newest version! It has an English APP for iPhone IOS/Android, and a computer software. It is designed with a built-in Bluetooth.

And BMS also supports computer software ( you need to buy a USB adapter separately).

More functions are developing now!

Attention:
The newest BMS must to use the newest APP or software! An old APP can't program the newest BMS! Please contact us for the newest app and other documents before using!

Supported Batteries:
10S-24S li-ion battery (30V-102V Lithium battery cell)
13S-24S lifePo4 battery (30V-88V Lithium iron phosphate battery cell)
15S-24S LTO battery (30V-68V Lithium titanate battery cell)

Functions of the BMS Battery Pack Protection Board:
- The default is the li-ion parameters. When you phone connect bluetooth, you can click and set up lifePo4 / LTO parameters. The default setting is 24S, if you use it for other number of cells , change it in the APP.
- Single cell voltage detection range 1V-4.6V. High precision detection cell voltage error is less than 5MA
- Charging current 50A
- Discharge current: 70A 100A 150A 200A 300A 300L to choose
- Balance current: 200MA. Controlled balance mode, when the charging is started, the voltage difference can be detected by the detected voltage difference to be greater than the set value.
- Bluetooth connection: support phones for Android/iphone IOS phone
- Supported cells: for Li-ion, Lipo, 18650, Lifepo4, LTO and so on
- Voltage accuracy: Single cell voltage detection range is 1.5-4.6V and it supports a variety of cells, with accuracy error within 3mV
- Wire-break protection: detect wire which is not welded well and causes wrong voltage. Balance wire break cell protection
- Overcharge protection: Connect to Bluetooth to set high-precision detection voltage, single overcharge protection and total voltage over-voltage protection
- Over discharge protection: Connect Bluetooth to set up high-precision detection voltage, single-cell over-discharge protection and total voltage under-voltage protection
- Short circuit protection: Can be connected to Bluetooth to set the short circuit protection value, change to 0 is turn off short circuit protection
- Over-current protection: can be connected to Bluetooth to set up the over-current protection value (maximum 300A)
- Current detection: within the current range of the purchased protection board
- Temperature control protection: The protection board has built-in balanced temperature control, power temperature, and can be connected with 4 temperature controls to prevent high temperature danger.
- Balance current: 200 mA, high voltage versus low voltage discharge balance
- Discharge current: refer to the current in the purchase selection as the peak discharge current
- Coulomb counter: compensation 1-24S battery connection between the chip resistance is too long, causing the wire resistance to be too large, the cell voltage is too large during the charging and discharging, can not be used normally
- Connection internal resistance: based on current to time scoring, accurately calculate the remaining battery

About Starting and Closing Buttons:
1. If the protection board is turned off due to abnormal power failure, only a short press button is needed to start the normal operation of the BMS.
2. During the normal operation of the protection board, press and hold this button for more than 5 seconds, then release the button, the protection board will automatically turn off the power, stop working, zero power consumption, short press can realize the display of the matching screen of the switching protection board.
3. Protection board If the discharge tube is not turned on for more than 5 minutes, the protection board will automatically turn off the main power, stop working, and consume zero power.
4. If the BMS power supply is turned off for the reasons of the second and third conditions, press the power button for 3 seconds to start the normal operation of the protection board.
5. If a matching display is connected, short press this button to switch the screen display.
6. Power button Please ensure good insulation, otherwise it may not be able to automatically turn off the BMS power supply.

About Onboard Bluetooth:
Bluetooth is turned on only when the mainboard is not in standby status. After 3 minutes the board is power on, board no current will enter standby status and Bluetooth will be turned off. Having the discharge or charging current , the system will cancel the standby status and Bluetooth will be turned on. You can observe the power led lights on both sides of the protection board. If they are always on, you can connect Bluetooth. If the system is standby, you can short press the protection board start button to activate Bluetooth once. Or re-start the protection board to activate Bluetooth. Make sure Bluetooth is turned on. In the phone's system settings Bluetooth settings, search for Bluetooth devices. Search once without searching. Please search multiple times. The name (BMS_ANT) sometimes shows null, click the pairing password 1234. Open the APP you download and click Connect the device, select the device you just paired to connect.

Protection Board Calibration:
1. Single cell voltage calibration: You can adjust the "system reference voltage" (the default is about 3.0) to slowly increase the size of 0.001, turn down, you can change the unit voltage value until accurate!
2. Total pressure calibration: You can adjust the "total pressure calibration parameter" (the default is about 3330), slowly adjust the size of this value, you can change the total pressure until accurate!
3. Current calibration: You can adjust the "current sensor range", slowly adjust the size of this value, you can change the current until accurate!
Note: Do not change the "Power Start Current" item in the parameter setting. If it is too large, it may result in burning and discharging the MOSFET!

About the Automatic Balance Function:
The auto-balance function is mainly a function that sets the battery's difference too much. Users must use it when the battery is fully charged or nearly fully charged. When the battery is fully charged, unplug the charger and click " Auto balance, at this time, the protection board will automatically balance until the battery pack voltage difference is less than 0.001, or the user clicks on "automatic balance" again to turn off, whether the automatic balance is turned on or off can switch the screen to "system state" to view "balance "Status. If "Auto balance " is displayed, it means that the automatic balance is in progress!

About Balance: The protection board balance is automatically controlled by the program through the configured balance parameters, where "balance limit voltage" is interpreted: when any cell voltage detected in the system exceeds the configured "balance limit voltage", the system exceeds the balance limit voltage. All the cells are discharged and balance ; "Balance Control Voltage" "balance Pressure voltage Difference" explains: These two parameters are the parameters for controlling the battery charging when the battery is charged, the cell voltage is higher than the balance control voltage, and the highest The lowest voltage difference is greater than the balance voltage difference, and the charging current is less than 15A, the charging voltage difference will be started. If the charging current is greater than 15A, the system will start the charging differential balance after the charging over-voltage protection. If the battery is fully charged, placed at rest, and the voltage difference is greater than the set value, the system will automatically start static balance.
