Heltec Relay Smart BMS 4S 500A 7S 8S 10S 13S 14S 16S 20S 32S lifepo4 bms with BT UART 485 CAN for 3.7V 3.2V Lithium Battery Pack

$150.00$355.00

Description

Above 32S BMS Customized

Pls Contact us if you want to know more detail or you need a high voltage system

This is our real project for 110S 352V Solar Energy Storage

This client just want save money choose two package , one is 55S, but it is not good for package or any repair . So if you need high voltage bms system . Just contact us .

For example:
 
If one battery is packed in 16S, and 10 pack in total, it’s 160S 512V battery pack.

Therefore, you need 10 pcs slave bms board and other accessories.

If it’s 64S system,consider two 32S batteries pack in series, the selling price is the same as the 36S. So just select the 36S slave board will be fine.

For more info.of high voltage battery system, kindly contact us in advance
Below is the application of 110S lifepo4 Solar energy storage system (Battery is not included)

Suggestion

Below 200A choose 2 Relay is enough

above 200A choose 3pcs relay

if used on like Heavy Truck start up. choose 4pcs relay

if you want to USE ON RS485 OR CAN , you need buy a Serial port module as below:

The scheme of control relay

 

Compatible with battery pack.

App modifies parameters, supports Li ion and lifepo4

Products schematics

It can control 2-4 relays to control power off, connect with Hall sensor and shunt, and charge and discharge different ports.

DC relay

Customers need to equip their own relays, select the required current, and support the choice to cut off the positive or negative wire.

Various mainstream relays can be used, with convenient selection and more stable use.

3s-4s is collected by shunt and 6s-24s is collected by Hall sensor.

Cables mark

Each cable has a corresponding mark to facilitate customers to identify the corresponding function

Bluetooth module

Bluetooth transmits signals, mobile phone APP receives information, and the effective distance is within 10 meters.

APP

You can view the battery status and adjust the BMS parameters by Phone Bluetooth APP. If you don’t know how to use it, please contact us to get the English manual.

Note: iPhone can only view parameters but cannot adjust parameters.

Balance Function

After setting the battery voltage difference between 0.02V-0.05V, it will automatically turn on, and the balance current will be 60mA.

*This balance power can only play an auxiliary role. If the actual deviation is large, a special balance instrument is required

PC software

Our development and adaptation of the PC BMS PC software supports monitoring parameters, modify the configuration and other functions. Notice: It must be used with UART or RS485 module to USB . Please contact us to purchase if you need it.

NTC

The product has 3-4 temperature sensors with a length of 500mm. It can collect current battery temperature information.
