Packing list :

1PCS 20S 60v (20A 30A 40A 50A ) Lifepo4 BMS board

+ Bluetooth module, android App (send by E-mail, contact us)

  UART to  Bluetooth  module  should use together with the board.  so you can monitor the board, and set the parameter.   Bluetooth module can connect to smart phone,  right now only support android 4.3 above.   APP support English version, you can change language.    Main Features: 1)Smart BMS with app controlling; 2) Balance & Balance display; 3) Mulit Temperature switches); 4) MOS transistor can control the battery charge and discharge; 5) low standby current consumption. 6) with UART interface, Bluetooth interface, smart phone. 7) over charge and over discharge can set by software( APP).   Parameter can set by software(APP). Balance current: 50mA      3.2v lifepo4 cells is 3.65v * S= charging voltage. ​3.7v li-ion lipo cells is 4.25v/4.20 * S= charging voltage. Size: 100*95*15mm   Adjustable Parameters: 1.Balance voltage setup:　Balance voltage Range:  3.3-4.2V  2.Over-voltage voltage setup: Charge voltage Range :   3.6-4.3V 3.Under-voltage voltage setup: Discharge voltage Range :  2.0-3.3V  4.Over Charge/Discharge current Setup....   Referance Battery Show  by Smart phone : Total voltage show Voltage range show Each cell voltage show Min/Max voltage show Nominal capacity show Remaining capacity show Percentage capacity show Charge, Discharge current show Charge/DischargeTemperature show Reminder Speed K/m show Average Seed K/m show Total mileage show Travel Time Show   Note: this BMS with balance function. your battery need matching, battery should have good consistency, if not sure, please use new brand battery.      After the protection board is connected, after normal communication, please modify the nominal capacity to the actual capacity of the battery; the cycle capacity is set to 80% of the actual capacity of the battery.   The protection board is to jump the line according to the number of strings you need and set the number of protection boards with the upper computer. It does not accept the number of modified strings. Please do not change the number of strings at will. The company integrates research and development, production and sales of power battery protection board as one, and has the ability to complete large-volume orders. The powerful manufacturers can cooperate with our company to purchase our mature power battery protection board in batches. The protection board communication port can be used to set various protection voltage, current and other parameters, which is very flexible. The protection board has strong loading capacity, and the continuous discharge current can be up to 60A. The protection board can also accurately read the battery pack power information through the communication port; the battery capacity (SOC), remaining battery capacity (RM) and relative remaining power can be obtained directly through this port. Battery related information such as percentage (RSOC), battery voltage, current, temperature, etc.      Features:     ● 7~10 batteries in series protection     ● Various protection functions for charging and discharging     ● Intelligent balance processing of the battery core, the balance current can be flexibly adjusted by external devices     ● There is corresponding temperature protection during charging and discharging     ● Over-current and short-circuit protection of hardware     ● All protection delays are programmable     ● Standard UART interface     ● Accurately report battery current battery information     ● PC software support, flexible adjustment of various protection parameters of the protection board     ● Multiple working modes for flexible control of quiescent current consumption     ● Sleep mode
