## Description

Actively balances 3-10S Li-ion, LiFePO4 or LTO battery packs, transferring energy between cells up to 1A for better autonomy and reduced wear. Includes Bluetooth with monitoring and settings from the app on your phone or PC, RS485/UART communication and equalization accuracy ±20mV, with very low idle power consumption. Comes with external Bluetooth module and 10S balance cables.
Active hardware balancing module for Li-ion, LiFePO4 and LTO batteries, equipped with Bluetooth interface on RS485 and capable of a transfer between cells of up to 1A.
It can manage between 3 and 10 battery series, having a balancing current between 0-1A, with a low power consumption of 250uA and a balancing accuracy of ±20mV. It operates at temperatures between -20°C and 60°C and is equipped with RS485 and UART interfaces for communications, supporting both phone and PC applications.
Multiple operating parameters can be set from the application.
The product comes with an external Bluetooth module and balance wires with a 10S compatible plug.
Specifications:
Compatible battery type: Li-ion, LiFePO4, LTO
Swing current: 0-1A
Quiescent current: 88uA for 3-4S configurations and 300uA for 5-10S
Power consumption: 250uA for 3-10S
Conditions for activating balancing: Individual cell voltage above 3.3V (settable)
Operating temperature: -20°C to 60°C
Swing method: Active swing
Equalization accuracy: ±20mV
Communication methods: UART/RS485
Dimensions: 65 x 115 x 19mm
Use:
Make sure the module is connected correctly according to the instructions specified for the battery type.
Settings can be adjusted for the desired voltage and current using the RS485 or UART interface, via PC or phone application.
Before powering up, remove the plug from the module and solder the battery terminals. Then insert the balance plug into the module.
In case of use in a configuration less than 10S, proceed with connecting the batteries starting from the NEGATIVE terminal (0V) Then connect the rest of the cells. The wires that remain without connected terminals will remain free (in the air) but the LAST RED WIRE will be connected to the FINAL POSITIVE . Only in this way will the module be powered.
Proceed by accessing the application and setting the correct number of cells in series, followed by a RESTART of the module.
The standard password in the application for changing settings is 123456 .
