Thanks for the information Ken.
I have no doubt this cold weather isn’t helping but I still feel somethings not right. After only 4 miles the speed drops to 24/25, its as if the battery is already losing power after a short trip. I will charge the battery inside and see if that makes a difference but I’d rather not remove the battery daily to charge inside. If this doesn’t help I will contact you to send the battery back for testing.
