OliverH Posted March 26, 2016 Share Posted March 26, 2016 I'm having difficulties with my new MSuper. After the 5th charging it looks like I get voltage drops (LED indicator goes down to 1LED and beeps). This after 50 m with very moderate/ slow speed/ fully charged. Looks like less than one battery pack works. I had the feeling today that the battery gets better and better after riding and specially after downhill tracks (correct charging voltage). So I did sone measuring after 1h tour. The MSuper comes with the fan less power supply. This is advertised with 67.2 V and I measure without load 104 V. On the charging connector of the Gotway I measure 86-104 V which looks to high. A reference measure at the IPS power supply shows 67.2 V so the multimeter should be fine. Can someone give me a reference measure of his MSuper/ power supply. I keep the MSuper untouched now. Link to comment Share on other sites More sharing options...

Your values are what I expected and what is advertised on the charger. As the value I measured would blow the mainboard there's something wrong with my multimeter but the problems of my battery exists, voltage drop in seconds.

OliverH Posted April 24, 2016 Author Share Posted April 24, 2016 I made a first ride with the replacement battery pack and the first charging today. The LEDs still come down fast on inclines but not to one LED immediately and no beeping. I was very cautios on riding as I was not sure how it reacts. It comes back to 4 LEDs immediately when load goes down. That wasn't so before. As I replaced the batteries one of the charger ports on one battery fall apart as I removed the tape. It wasn't plugged correctly together. Maybe it never charged the batteries full as it only charged one pack and made a energy transfer to the second battery pack and stopped charging to early. I ordered an additional battery to 880 Wh from 1RadWerkstatt to improve the behaviour that the MSuper can handle my weight better. So looks good now. Have a look on the next real tour. Just started the planing for a nice trip in france. Link to comment Share on other sites More sharing options...
