Original Bluetooth Guide


APP Introduction

This application is independently developed and designed by Shenzhen Wattcycle Power Co., Ltd. lt specializes in monitoring lithium batteries, providing real-time status readings such as the voltage of each battery series charging and discharging current, alarm prompts, protection status, etc. This allows users to clearly understand the health status of lithium batteries and ensure their safe use.

APP Running Environment

This application can be installed on Android 4.3 or above, supports Bluetooth 4.0 devices, and requires GPS usage permissions for Bluetooth functionality.

APP Download and Install

Users can scan the code to download and install the APP in the following ways:

  3. Exhibit the total voltage of the battery.
  4. Reveal the magnitude of the charging and discharging current.
  5. Display the power size.
  6. Present the number of battery pack cycles.
  7. Display battery status, ambient temperature, MOS temperature, first group cell temperature, and second group cell temperature.
  8. Display the voltage details in multiple series of battery cells, encompassing voltage difference, average voltage, minimum voltage, maximum voltage, and voltage difference for each series of battery cells.
  9. Present alarm information and set parameters
  10. Set parameters.

* Unauthorized alteration of the parameters of the BMS board may cause abnormal operation of the battery and affect the product warranty, lf necessary, please contact the customer service to obtain the password.

Quale codice devo inserire nell’applicazione?non riesco ad entrare dove si trova

Valentino ,

Why does the discharge switch turn on automatically when I charge the battery with no load?

Jay Beery,

Your documentation booklet DOES NOT explain how the CHG and DSG switches work. Is bright green ON or OFF?

Jay Beery,

I just got 2 of the 300ah mini batteries and in both of them the tops came off is loose. Before decide if I return them or just seal them up I want to check the charge and capacity status with the app. However I can’t connect to them with Bluetooth. It is asking for a device name. In the instruction video it says that there is a sticker with the name but not on my batteries. There is a SKU number but that does work. So how do I connect if there is no device name showing up? Is the bms defective on both batteries?

Claudio Derungs,

I figured out the default password. It’s just a bunch of eights.

Sampy Hardin,

What is the best way to monitor the Bluetooth data using another device like a raspberry pi? I would like to be able to collect a history of data so I can track voltages and other data remotely or by using cloud services. Any Home Assistant integration?

Tom Jenkins,

I need the password to access the battery thank you

Joseph Drawdy,

With the latest release of BMS Meta on Android (12/29/24) why do I need the password to turn on/off the CHG Switch and the DSG switch??

Jim,

Please send me the password for the 100ah trolling Bluetooth battery.

Lou,

Like everyone else, i need the password to access the settings on my new battery. Im actually really upset there is no information included for this. Im beginning to see that the saying “you get what you pay for” applies for lifepo4 batteries as well. This is ridiculous

Derek,

Like everyone else here I need the app default password. Not sure why it would not be included in the app instructions.

John,

Please send me 1) The password to the IOS “BMS Meta” app so I can set my own PW and 2) how do I change the temperature display from Celsius to Fahrenheit?
Thanks

Jerry Bergosh,

Great packaging on the 12V/100Ah Mini!

Please send me 1) The password to the IOS “BMS Meta” app, 2) PDF versions of the manuals for BT and the Owners manual for the 12V 100Ah Mini. Thanks!

Mike Visket,

I just bought 8 each 12v 100ah batteries. I plan to use them in 4S2P configuration.
When I bring up the Bluetooth APP, I am seeing 8 individual batteries.
Is there a way to see all 8 batteries at the same time?? Having to switch from one battery to the next is rather time consuming.

Bo ,

I also need the password to check and possibly modify the BMS settings.

Bo Henderson,

Can you please provide me with the password to modify my batteries settings!
