I picked up a second battery. One to get me where I am going, one to get home again. Even though it is even more weight on my already heavy T1 Pro, knowing I will have enough juice to get back frees me up from planning every detail, and leaving enough wiggle room if I want to check something out. Would be great if Fiido had a cushioned bag, or a rear mountable crate with a slot to hold the battery centered. Not plugged into the bike, just charged and stored there. I will figure out something and let everyone know. Thanks.
