Brammo Empulse / Re: Not charging over 90%

If you press the 2 buttons simultaneously, you can see the battery voltage.
You see the maximum and minimum voltage of the pack. The maximum voltage you can pick up is 4.16v. If it is balanced the value of the lowest cell should be around 4.145v.
When the values are very different the load stops when the maximum value is reached (4.16), and then the "PPP" appears, that is to say that it is taking energy from the cells with the highest voltage, so -0.3KW appears.
When "AAA" appears it is equalizing the cells.
The BMS is continually doing this cycle. If after 30 minutes, the values remain the same, it is best to switch the charging off and on again.
If it still does not change, use the bike and try again to see if bms can solve.
good luck
