Hi everybody, (I must share this with you, then it's off my chest)
I have a converted VX-1 with a new batterypack Samsung 29E 18650 36S36P, a runke charger and a new BMS.
5 months ago I bought a new BMS at Vectrixparts Poland. All seems fine till now.
During the last trip, three weeks ago, I suddenly got a red battery indicator. Strange, because the batteries were only half empty.
When i docked with the diagnostic tool everything seems ok, all batteries nicely 3.62 volts.
When i charged the batteries, there was 1 cell-reading that wasn't correct and ....fast rising.
In 2 minutes it reached 4.00 volt. "???", "That can't be right?".
Ofcourse the charger then decreased ampheres because the danger of damaging the cells.
First,I measured all batteries by hand, no problems there.
Second,I thought it could be a broken wire. I managed to analyse which cell and which wire it could be.
Because there are 36 wires and a difficult access, I decided to replace the relevant wire.
All with the same result.
Third, I decided to charge without a coupled BMS. All cell reached without problems +/-3.98 Volts.
Resume: batteries ok, charging ok, wires ok, BMS.....seems suspicious.....
Then I decided to contact the guys in Poland. After two weeks waiting there was no response.
4 days ago i sent another email. Nothing ......Zip.
What is the matter with those guys? Are they still in business? anyone......
