Hello
With these types of repeatedly had trouble with the battery cell crossover cable, or bad contacts. The individual cells are easy to isolate the error, measured as the contact with evil, there's no cell voltage of 2.2 Volt. Reported no errors, and sometimes the battery is 100% showed, but did not go neither forward nor backward. This phenomenon is sometimes was switched to one of the light flashed on the screen. I usually clean the battery terminals and sometimes because the acid eats the brass contact, I make a washer under the bolt to be tightened better. Of course, the jumper should also be replaced.
Best regards, Laci
