Popular Post Cody Posted June 13, 2020 Popular Post Share Posted June 13, 2020 Battery Monitor System [Aka BMS] Inside the packs I can see that electronic protection circuit are not complete, the critical component are missing: No fuse, (really helpful in case of a short circuit) No temperature sensor No Schottky diode, (to prevent current flowing a dead cell) No Single cell voltage clipper (if cell damage occurs or CID fault) A single wire assure the safety cutout, in an unknown way ! the wire seem to have been added by an unqualified worker, there is no visible solder pad where it’s soldered. It look like added quickly on the production witch is completely unreliable ! and this is not reliable at all, in my faulty pack the battery still charge on overvoltage condition ! Cell Arrangement: Each single cell group shall be insulated from others. Insulation between cells is missing! [Added red bars, where it shall be] - the cell PVC shrink sleeve shouldn’t be used as an Insulation layer So many issues on the battery pack manufacturing ... #Hoverboard_fires... pleas not again i'm trying to reach the factory, if anyone have their contacts if would be greatly apreciated 4 Quote Link to comment Share on other sites More sharing options...

null Posted June 13, 2020 Share Posted June 13, 2020 (edited) Where is this pack from? Recent or old production? Doesn’t sound very serious indeed, especially from KS if they want to be the safety brand.. Edited June 13, 2020 by null Quote Link to comment Share on other sites More sharing options...

..... Posted June 14, 2020 Share Posted June 14, 2020 Stuff like this makes me reconsider my entire outlook and faith in the euc manufacturers. So much damn money invested in these wheels, only to find things like this being shipped out as new? Hmm... Quote Link to comment Share on other sites More sharing options...
