Globewheel Posted January 17, 2021 Share Posted January 17, 2021 (edited) I get some wired fluxating charging issues. This happens with any charger I use. I have three 100.8 v chargers. I have included a video of the behaviour on my cycle satiator so you can see what I mean I am using the advanced menu to demonstrate whats going on. I dont know what the values on the sherman mean. https://drive.google.com/drive/folders/1VavGwI_17mhvkfBHimypOL-08XIXwNyR?usp=sharing Edited January 18, 2021 by Globewheel Quote Link to comment Share on other sites More sharing options...

The other "normal" chargers change between red and green light? 6 minutes ago, Globewheel said: I dont know what the values on the sherman mean. I assume there exists no manual for the LCD screen? From time to time new screen content pops up here... 6 minutes ago, Globewheel said: https://photos.app.goo.gl/PCWguQAQU9HmZmue7 Seems like continous repetitive charge interruptions. Imho to evenly for some loose contact? Maybe some "thermal induced loose contact"? You tried moving cables, connectors, slight shaking? BMS can cut chargers off once single cell group voltages exceed 4.2xV. Charging gets enabled again once the cell voltage goes down to ~4.2V by discharging over the balancing resistor. This cycle should be much slower, maybe a dead cell could lead to such symptoms? Maybe Veteran BMS/motherboard supervise other values which could lead to such effects? Or it's simoly just some weird malfunction and the respective part needs to be replaced/repaired? Best to contact the reseller. Especially if the wheel still has warranty?!

null Posted January 18, 2021 Share Posted January 18, 2021 My charger (stock YZPower450) makes a cyclic sound during the entire charge, at about at the same speed as your video. (seems others also have something cyclic going on) I'll try the advanced display next time charging, and also look at the rhythm compared to yours.
