Afaik battery voltage drops during heavy use. For example, after approx 20km when my DIY battery packs shuts down on trail mode, I can just power it back again and ride for a couple of km on eco
I obviously asked about one like I said in November and they was on back order and £540 So I'm guessing it will still be the same now, the hardest thing was trying to get a shop to help. Only shop that answered me was Wheelbase so you could give them a try.
