Product Detail

150a 12v 4s Protection Circuit Board With UART and RS485 for Lifepo4 Battery

Product Introduction

ACEY-SP04S028A It is specifically for small energy storage batteries, street lights, 12V Lead-acid for lithium battery and other products.The software protection board solution designed by stringing battery packs can be applied to lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium iron phosphate, etc.

The whole system adopts TI( The front-end acquisition chip of Texas Instruments+ MCU , Some parameters can be flexibly adjusted through the host computer according to customer needs.

Features

3-4Series cell protection in series.

The cells are intelligently balanced, and the balanced turn-on voltage and differential pressure can be flexibly adjusted through the host computer. Optional charge equalization or static equalization.

Integrated hardware protection functions such as overvoltage, undervoltage, overcurrent, and short circuit.

A variety of working modes, the protection board can disguise and go to sleep when it is static to achieve the purpose of reducing power consumption.

Comes with two communication ports, which can read voltage, current,SOC, temperature, protection status and other data.

UART (TTLlevel) can be externally connected to Bluetooth, computers and non-battery powered devices, isolatedRS485Can communicate with controllers, chargers, etc. device communication.

There are two temperature detection probes by default, there are two temperature detection probes, one for detecting the internal temperature of the protection board, and one for detecting the temperature according to customer requirements.
