Update:- Pedal sensor still not working but I have got the throttle to give full power using the P4 setting on KT LCD5.
My riding style is to potter (8 to 12mph) without assistance until I need to ascend. I can now manage all the inclines I used to use but have been avoiding.
Apologies if this has been on the forum and I haven't seen it but Jimmy (ebikebatteries.co.uk) is back. So I will stick to 36V and have the batteries recelled by them.
I will ask for help re the pedal sensor when winter is over.
