Mental Note, Check the battery terminals!
It would seem that I did not have one of the battery terminals tight enough. The battery still tests OK, but I have replaced it and the balance circuit with some spares.
I am not sure why the terminal overheated as I am careful about tightening them It may be that I forgot to tighten it properly or maybe there was a bit if swarf or a jager preventing the strap from connecting to the terminal properly.
I use spring washers to prevent the screws from vibrating loose.
I am probably up to about 15 cycles. Average about 1 trip per day of between 5km and 20km, and 35km once per week.
Mal, hopefully, this will not repeat gain, do you think it was because of road vibration or just a mistake during install phase?
ReplyDeleteBtw. what is your current charge cyclus on these batteries, still in the early brake-in 20-50 charges area?
