    Can not connect to apps. Tried old and new. What steps should be taken.

    I’ve used several Bluetooth batteries and their respective apps, all see to be quirky in their own way. Your instructions seem to skip the user information. Mostly how to connect to the battery. I can’t make it charge. I’ve tried to toggle the charge and discharge tabs and the battery just sits there at 25%.

    BMS app for 2x 314ah displays the devices bit gives device connection time out. So no connection. How to solve?
  • Herbert 2025-07-02 02:30
    Just received 2x 314amp however wattcycle app is very basic. Do I need to install the BMS version?
  • Alan Shedd 2025-06-26 09:27
    Need clarification – I read that Wattcycle App doesn’t provide cell-level data on an iPhone for 280 AH mini. Is that true or has the app been updated?
  • Karen Elizabeth Lally 2025-06-20 09:28
    Please update manual for new app. What does standby mean? Are there notifications as the other user asked? Do I need to update the settings for my battery?
  • Lorenzo 2025-06-19 20:43
    The instructions provided on the site do not match the app and it would be nice to have instructions that would actually show you what each selection means.
    So basically, there is no effective app available as promoted.

    All of the questions are relevant to all users. Can answers be put in an FAQ please to be respectful to users.
  • Gregg Garthright 2025-06-09 01:59
    I like the app, but the instruction manual in the app doesn’t match the software. The manual refers to “BMS Meta” – it looks like it has features not present in Wattcycle.
    I like the idea of an app, but it’s hard to get the most out of it when I don’t know how it’s supposed to work.
  • vic 2025-06-08 02:39
    For a quality product like this, a little improvement in the app is necessary.
    1. I can’t understand why it’s not possible to indicate the time remaining until the discharge limit specified by the user, not the BMS’s.
    2. And if I had to ask, an notification when the user-set limit is reached. It would be almost perfect.
    Thanks a lot
