Hi I saw your suggested fix on another thread. I wasnt overly confident of doing this as I dont undserstand what you meant by the output port. Is it like back charging and py-passing the BMS? Ive also just found out that the fuse holder had some dirt in it and was not showing voltage at the battery connectors it is now after cleaning it up

Thanks for the reply, yeah Ive tried that. When I plug the charger in the status lights on the charger dont change to 2 reds.

Hi everyone Im new to the site and would like some help if this is ok? I bought my wife a Vic Pendleton ebike a few years ago and its been sitting in the garage for a while after a house move and has not been on charge. I have searched youtube and online and have made some progress: When the battery was plugged into the charger it only had the red and green light showing - not charging. When I disconnected the battery from the charger I didnt have any lights showing any charge. I opened up the battery to check for any corrosion - none evident. I then noticed when I plugged in the charger lead that I got an arc and the battery charger was then showing 2 red lights. Mmm charging I thought?? When I pressed the battery test light I got all green lights except for the 20% light which was red. I disconnected the charger when the light went green / red and again no lights. I have opened up the battery again and checked for voltage and I do have 40.2v on the BMS from the VP and VG connections. When I check for voltage again at the DSG and VP connection I dont get any voltage. Im assuming there is a problem with the BMS?? Can anyone help please? Its a DEMETER 36V battery
