I am very sorry for the late response, I have made previous attempts but could not navigate the system. To get to the point I followed your advice exactly and the problem was immediate resolved. Thank you very much, I greatly appreciated your commitment and in my case your persistence. Kindest regards John e

My LCD controller is a KT-- LCD1. There is nothing in the manual about voltage selection so I assumed it was dedicated to 36 volts but I take your point, it could auto select. That begs the question about what I can do if it. Sorry if I have been slow to catch on but I hope we are now on the same page. I have tried to attach 2 pdf files that together conprise the users manual (2 sides of A4) but when attached the forum site says the files are empty. I am sorry this failed but I doubt the manuel would be any use to you. Thaks for your persistence. Best wishes John e

My LCD conytoller was supplied as part of my Cyclotricity conversation kit . It doesn't have a proprietary name but hsving checked the unit and available info. I am satisfied that it is limitef to 36 volt operation. Thanks for your post

Sorry. The lcd controller is correctly rated for a 36 volt system

Thanks for your post.I have checked the charger voltage and confirmed it is 42 volts. I will see what happens after a few charge cycles as you suggest. Thanks

Thsnksfot your suggestion. The lcd or der for 36v

Hello l am a new 88 year old male. About 12 months ago I bought 2 new batteries for my bike, they have not yet been used but I have given top up charges. I have now charged the batteries ready to use but when installed on the bike the controller indicates only half charge. The battery voltages measured at the output terminals is 40volts and 41 volts respectively. I can rule out a controller fault becsuse I have substituted a new one. I will appreciate any suggestions.
