yeah I also have the QS-S4 and it doesn't work for my mercane mx60 and no one in the UK has stock of the LH-100, any has any links and not from china as I know it could take weeks to come to UK
I have a ElectroBike and the 36v brushless controller says it can handle max current 13a, the battery I have brought says its a 36v 15.4a. is this ok to use with the conntroller or will it burn it out?
thanks Whoopee
