12v 314A BT Parellel problem - not fixed in 2026


  • 3 week old from Wattcycle-Europe and they have problems all the time. I thought you have fixed the parallel problem!!

    I have 2 - 12v 314A BT I parallel with busbars. Batteries are bought with one week apart and they have different firmware WT12_20004SW10_L447 and _L446, NO way to update firmware. The batteries behave strange under load. One show -1116 W other show -675 W during load at 1800 W.

    When loading ONE battery at the time they show 1800 W or 143,3A and 143,5A, almost the same.

    With small loads it is the same 

    I use "ExactMatch" mode and both batteries was fully charged before connection. The state of charge in % wary a lot when used for som time, one 85% and the other 63%. Or 100% and 85%. It differs a lot. It is always battery with firmware _L447 that show the lowest %.

    I have tried "Compatibility" with the same result.

    The "bind" dosent work, the app dont recognize the serienumper on eider battery.

    What do I do to fix thise problems?



  • I gues this is not the way to get help from custermer service. Any one knows where to get help when I have bought 2 new batteries, that behaves odd.
